I mention in that article how mathematical music is, and musical notation (for example, sheet music) is no exception. Everything is split up into parts and segments, starting with the whole form of a song, right down to the millisendth of a note, and vice versa. When you understand the form, and how each increment of that form is broken down, i.e. notated, then reading music is relatively easy.

3 Octaves C To C

With sheet music, a three octave scale in C would be written like this:

Low C to High C Scale

If we think in terms of a piano keyboard, middle C is the note in red. Anything below that is part of the “bass clef”, the curly sign on the bottom left of the diagram. Anything above that is the “treble clef”, and is described by the sign on the top left hand side of the music. The time signature is also shown on the left hand side of the music, in this case 4/4 time, the most common of time signatures. A bar means a whole section of that time signature, i.e. four beats. The horizontal groups of lines in the diagram that make up both the treble and the bass clef are called “staves”. There are 5 lines grouped together in a stave.

In the sheet music above, the staves are broken down into 6 blocks by vertical lines. Each block is called a bar, and denotes 4 beats, thus creating the 4/4 time signature indicated at the beginning of the music. The musical notes are then notated in time the with beat of the music, and thus the pacing of the bars.

Notes can be placed on a bar in the white spaces, or on the black lines, each line of the stave representing a note on the scale.

For the black notes E G B D F I learnt this rhyme as a child:

“Every Good Boy Deserves Favor”

And for the white notes it was F.A.C.E:

“F.A.C.E.”, face.

Notes

The notes in the music above are “crotchets”, meaning a single beat, and in 4/4 time, there would be 4 crotchets to a bar, making four single beats, 1,2,3,4. Once again, music being mathematical, a single bar can be split into further increments. We start with a Breve, often called a double whole note in American and German terminology. One note, 8 beats. It’s either shown over two bars (yet again, in 4/4 time):

Hear A breve

Or notated like this:

The diagram on the left hand side shows a hollow oval note head, like a whole note, with one or two vertical lines on either side. An alternative notation consists of two adjacent hollow oval note heads, as in the double noted bar on the right .

SemiBreve

Once again sometimes called a whole note in American and German terminology.

A semibreve is 4 counts long. So in 4/4 time, a semibreve would look like this:

Hear A semibreve

A Minim

A minim is two beats, the above diagram showing 2 minims in a 4/4 bar.

Hear A Minim

A Crotchet.

Four beats to the bar.

4-Crotchets

A Quaver

8 beats to the bar.

Hear the bar above

Quavers can also be split up into increments. So two quavers look like this:

Hear the bar above

A single quaver is notated like this:

The stem can be drawn facing up or down, shown by the flag on the right hand side of the note, depending on the path of the music.

Double this time are semiquavers, 16 beats to a bar:

Hear the bar above

The double line at the top shows it’s a semiquaver.

A single semiquaver looks like this:

The squiggly line after the notes in this diagram in a semiquaver rest (see below).

To a demisemiquaver, 32 beats to the bar, which is just getting silly:

Rests

If there’s a space in the music, or rest, this is shown as:

A whole bar:

This bar rest also translates as a two bar rest, when it’s shown, for example, after a semibreve:

The single bar rest (squiggly sign), meaning one beat:

The above 4/4 bar shows a crotchet, a crotchet rest and a two bar rest.

A quaver rest looks like this:

And a semiquaver rest has a double tail on it, shown after the two semiquavers:

And a demisemiquaver rest looks like this:

Keys

OK, so that’s the basic notes and rests, and how they’re shown on the stave. Now let’s look at keys, i.e. what they are and how to recognize them. I mentioned keys, scales and chords in the “How Music Is Constructed” article. Every song has a key (with only rare exceptions, for example, free Jazz). The key of a piece of music can be a complicated subject. But, in a broad sense, it means that the note the key pertains to is the song’s harmonic center, or tonic. In other words, if the song was in C for example, you could play the note of C more or less throughout the piece as a bass note and hear the key (see the section ‘Finding a song’s key’ for more info).

Music is also generally written in either a major or a minor key. The major or minor depends on the scale on which the key is based. The key of a song is shown at the left hand side of the stave.

The Key of C looks like the very first scale above, with nothing on the left hand side of the stave, having no sharps or flats. “C” is also sometimes written to denote the key.

The Flat Keys

F : 1 flat, Bb:

Bb: 2 flats. Bb and Eb:

Eb: 3 flats. Ab, Eb and Bb:

Ab: 4 flats. Ab, Bb, Db, Eb:

Db: 5 flats. Db, Eb, Gb, Ab, Bb:

Gb: 6 flats. Gb, Ab, Bb, Cb, Db, Eb:

Cb: 7 flats. Fb, Gb, Ab, Bb, Cb, Db, Eb:

By the time you get to Db, it’s getting ridiculous. 5 flats and above make these keys really hard to play for any musician. By just changing the key to either C or D, a simple half step in either direction (whichever is most comfortable for you, the singer), you’re making everyone’s life much easier.

The Sharp Keys

G: 1 sharp. F:

D: 2 sharps. F and C:

A: 3 sharps. F, C and G:

E: 4 sharps. F, C, G and D:

B: 5 sharps. F, C, G, D and A:

F#: 6 sharps. F, C, G, D, A and E:

C#: 7 sharps. F, C, G, D, A, E and B:

The same applies as above. From B onwards, these are pretty redundant keys.

Minor Keys

I mentioned relative minor keys in the article “How Music Is Constructed“, and how they relate to the cycle of 5ths:

A minor key has a flattened 3rd, 6th and 7th note. Each minor key is related to a major key with the same amount of sharps or flats.

So, looking at the diagram, it shows that the key of C is related to A minor. The key of C has no sharps or flats:

and neither does the key of A minor:

And so on round the cycle: the relative minor of G is D minor, D is B minor etc.

Finding A Song’s Key

If you have sheet music that doesn’t have a key written in the left hand corner, you can find the key in a number of ways:

1. It’s quite often the first or last chord, or else the chord the first chord resolves to.
2. It’s the predominant bass note (if the key is F, for example, you can pretty much keep playing an F in the bass and it’ll sound right).
3. If you have a keyboard or guitar, then if you can pick out chords it becomes much simpler. You’ll see certain chords repeating themselves. If the key is G, for example, you’ll find yourself playing the F# again and again. A big sign that the key is G.

Half Tones, or Semitones

What about half notes, or semitones, i.e. the equivalent of a white to a black know on the piano? This is notated by sharps and flats:

The diagram and the sheet music above show F to F#, a semitone.

Playing up octave using every note, i.e. every semitone, is called a “chromatic scale”.

Sharpening And Flattening Notes

If you want to write a note that’s not in the key of the piece, for example a semitone higher or lower than the current note you’re playing or singing, then this is notated by a flat or sharp sign before the note.

Hear The Bar Above

Once you’ve assigned the command to the music with a raised or sharpened sign, it’ll keep being played as such until you tell the music to do otherwise. So if you want to go back to the original note that fits in with the key of the song, then the opposite sign is used to once more raise or lower the note a semitone. This snippet is in the key of C. F is sharpened to F sharp, and then flattened back to F.

Dots

Hear the bar above

In the example above, there’s a dot after the crotchet, the first note. A dot after any note means “half as much again”. This makes the count of the dotted crotchet 1 1/2 beats, the quaver (half a beat) completing the first half of the bar, i.e. 2 beats, and a 2 bar rest completing the 4/4 bar.

The dotted minim 3 beats, the crotchet 1.

Ties

Ties work in 2 ways. They either simply tie the note together, as in the bar below:

Hear the bar above

A dotted crotchet (1 1/2 beats) a tied crotchet (1 1/2 beats), a quaver rest and a quaver for the first bar, with a semibreve the next bar.

The second crotchet is tied because it’s in effect tied to the 2nd half of the bar. The first dotted crotchet and quaver being the first two counts, the crotchet, rest and quaver making up the 2nd 2 counts.

Hear the bar above

A tied, dotted minim make up the two bars above. When a note is tied it means: play it once, for the duration specified. In this case across one bar into the next. The note above is 5 counts (the first minim being 2 counts, the next dotted minim, 3 counts).

Syncopation

“Dots” and ties create syncopation – changing the length of notes so they’re no longer regimented, i.e. strictly in time. Mixing up the length of the notes creates rhythm, and as soon as rhythm is introduced into a song, it becomes syncopated.

The examples used in the ‘Dots’ and ‘Ties’ sections above demonstrates this.

When thinking of the rhythm of a song, for example 4/4 time, it can help to count in quavers: one and two and three and four and etc.

For more on syncopation, check out the article: ‘How To Feel Rhythm‘.

Triplets

Hear The Bar Above

Another thing to now throw into the mix before moving on is triplets. This is simply a single note, but counted in three. To count a crotchet triplet, as in the bar above, hold your hand in an upright position and count “One, two, three”, moving your hand ‘up, down, up’. One is the upright position, two, the down, three the up position once more.

Triplets can be counted over any value of note: breve, minim, quaver etc.

Articulation

Articulation actually means, “how things are articulated”, or joined together, for example a skeleton or the syllables of a word. In music, the articulation means “what happens in between the notes”. The rests, the accents, the expression of the piece. And articulation depends on what’s at the beginning and end of each segment, as well as in between. We’ve already looked at rests and dots, and will be looking at some basic terms over the next few paragraphs.

Accents

In music notation, an accent mark means “accent the note”. The most common form being the fourth note in the diagram above.

The first note means staccato, meaning the last part of a note should be silenced to create separation between it and the following note, creating a note about half as long as the note value indicated.

The second note means staccatissimo and means a staccato note even smaller than staccato.

The third note, the teepee accent, means ‘play with a combination of accent and staccato‘.

The fourth note, the Accent mark, means that the marked note should have an emphasized beginning and then taper off rather quickly.

The fifth note, the tenudo mark, indicates that a note is to be separated with a little space from surrounding notes.

Legato

Legato is the opposite of staccato, and means that the notes are played “long”, very connected, like there’s no space between them, i.e. continuously. In the bar above, legato indicates this musical feel.

Slurs

A slur looks the same as a tie but has a very different function. Indicating a legato feel, a slur sign means “blend the notes together seamlessly so there’s no space between them”. With a tie, the note doesn’t move, but is “held”.

Slurs can be performed quite fast, as in the sheet music above. Along with violin sections, a lot of singers use slurs as an artifice, often to great effect. Christina Aguilera, Maria Carey, Celine Dion, Beyonce et al. Usually based around a blues or pentatonic scale (check out scales in the “How Music is Constructed” article), they’re a form of ad-libbing. And for more on ad-libbing check out the article: ‘How To Ad-Lib, or Improvise’.

Portamento

The first sign above means Portomento and/or glissando. Portomento means to wobble the note very obviously, similar to using a heavy vibrato, and glissando means to wobble the note and glide, upwards or downwards, a technique used extensively in opera. The bottom symbol above shows the sign for ‘glissando up’ and ‘glissando down’. Portamento was also used extensively by early sythesizer players (think Rick Wakeman), rock guitarists when using the whammy bar(nearly every heavy metal guitarist alive or dead), and, last but not least, the classic portomento instrument, the organ. Hammond in particular. Plus church organs and everything above and between.

Scoops and Falls Offs

These signs are used by composers to show they want a slide down from the note, or a scoop up to it. They haven’t been standardized (except maybe for glissando, the last one, yet their appearance is pretty explanatory.

Grace Notes

Hear example

A grace note means, in essence, an ornamental note, an embellishment to the original. Either on the way up or down to the target note. Used extensively in classical music, this kind of embellishment is usually left up to the taste and skill of a performer in modern genre music, but occasionally you might see it notated.

Songs

We’ve now looked at the basics of music notation, let’s take a look at some sheet actual music and what you might expect to encounter.

Songs come in many shapes and sizes, and, although rules are made to be broken, most songs are written in the form of either a verse, or verse and chorus, or verse, chorus and bridge. The classic form for a song is verse, verse, bridge, verse. This form of song is called a “standard”, and refers to the works of composers such as Cole Porter and Irving Berlin. Usually 16 bars for each verse and 8 for the bridge (middle bit), 32 bars in total. Modern genre songs often veer away from this format, so you might just get a verse and a chorus repeated with a small solo section, for example. Or just a riff or hook, repeated at various times throughout the song (for example, rap and hip hop).

Let’s look at the formation of the song used in the “Singing A Song – Putting It All Together” section of the program, the timeless “Amazing Grace”. In this song there are simply 16 bars to each verse, which make it like a traditional Folk song. So we need only look at a single verse to see the basic form of the whole song. To demonstrate this, the version below is a simplified form of the chords and tune, in the key of Eb.

Hear the verse above

Not the most inspiring of versions when there’s no groove, i.e. syncopation, just the basic tune. However, once again we have the time signature in the top left hand side of the sheet music, 3/4 time, demonstrated by the click track. One and two and three.

The chords are played depending on the bars indicated. The notes of the tune are part of the chord within the bar.

This sheet music is split into the treble clef (higher) and bass clef (lower). In this instance, the chords are in the bass clef, the tune in the treble clef. It’s in the key of E flat, shown at the left hand side of the music.

The beginning chords are E flat, the key of the song, then A flat, the fourth note in the key of E flat, and then back to E flat again. And the tune fits in to the key of E flat with every note:

The 9^th (the lyric ‘how’) simply means that from the root of E flat, or wherever you start the scale, you keep counting up 9 notes. So after an octave, E would become the 9^th, G the 10, A flat the 11^th, B flat the 12^th and C the 13^th.

Amazing Grace Full Song

And moving on to the full sheet music of the Amazing Grace version (above) used in the Full Program section “Putting It All Together: Singing A Song”:

This is another 3 stave version of the sheet music, with voice, piano and bass in that order (piano and bass are grouped by the curly sign at the left hand side of the page). It’s in 3/4 time and the key of Eb, with a 4 bar intro.

The chords have been somewhat changed from the first ‘straighter’ version, bringing out the blues and Gospel feel of the song (for more on chords, chord voicings and construction and how they ‘fit in’ to a song, check out the article “How To Ad-Lib, Or Improvise”. There are four different vocal versions of Amazing Grace, soul, Jazz, Folk and Country, with sheet music).

D.S.Al Coda

There’s one sign used in the sheet music above that’s net yet been mentioned, however, D.S. al Coda. Loosely translated, this means ‘ repeat back to the coda sign’. And when the coda is reached, i.e. the coda symbol, to jump to the end of the piece, symbolized by a second coda symbol, and to play to the end. This is notated in the music above as a coda sign at letter A:

There are repeat signs in the same bar of the music. On the next page at the end of the second set of staves is another repeat sign. These two signs are always seen together and mean, of course, ‘play round and round’. The writing ‘repeat A (coda sign) X 5 take Coda last X means just that: 5 verses and then the coda sign, the circle with a cross in it, and jumping to the second coda sign with Coda written by it, to the last 5 bars of the tune.

And So…

There are a plethora of examples of the notation described earlier in the article in the “Amazing Grace Full Version” sheet music above. Semibreves, minims, crotchets, quavers, triplets, rests, a letter A, dots, ties, slurs, a Rallentando, coda, repeat signs et al. Ah yes, and the little sign at the end of the song, the slur with a dot above it on the very last bar, means ‘pause’.

For more information on how to read sheet music, chord voicings and musical notation check out the article “How To Ad-Lib, Or Improvise”. There are four different versions of Amazing Grace (soul, Jazz, folk and Country) with sheet music explained and vocal MP3 examples.

I took classical piano lessons as a child, and music never made any sense to me. Why the endless scales, etc, and what did that have to do with playing “Fairy bells”? It was only many years later that I made any kind of connection at all between the two, when I studied Jazz music theory. Much of the complexities of music were explained in a way I could finally understand. So for those of you to whom “how music is constructed” is also a complete mystery, this might help, in part, to shed some light on the subject. “Why should I bother?” is the obvious question that comes to mind, and the reason is, that understanding some music theory can help tremendously when performing a song. It helps one hear what the band is doing, even if you’re simply singing along to a karaoke track. For when you understand how everything is working together, and how the tune, i.e. your part, fits in to that whole, you’re no longer the lone voice out front, but intrinsically part of the whole thing, a necessary piece of the musical puzzle. And since most modern genre music is a distillation of the blues, which Jazz springs from, and European classical harmony, most of the songs you’ll be singing will usually be using this notation and a distillation of these harmonic ideas in one form or another.

Although music seems to be all about feeling and emotion, at its root it’s extremely mathematical and also beautifully simple. From there can spring enormous complexity, like a mathematical equation. Let’s look at a simple major piano scale to demonstrate this, C to C:

C to C

Hear The Scale C to C

A major scale is 12 notes in total, consisting of tones and semitones (or half tones). Every song you’ve ever heard (and by this I mean Western music), every piece of music ever created, springs from the notes of just one simple scale. Notes plus rhythm equal music. For within this major Scale of C, just taking the white note keys as an example, are also the scales of D, E, F, G, A and B. And if you use the black notes, you get the scales of D flat (or C sharp), E flat (or D sharp) etc, etc and so on up the scale, 12 scales in total (more of this later), 12 notes to a major scale. Already, what appears to be very simple has the potential for considerable complexity.

We calibrate scales by how many white and black notes there are. For a major scale its tone, tone, semitone, tone, tone, tone, semitone.

A semitone is a half step, a tone is two semitones together, a whole step, for example C to D on the piano keyboard above.

Hear A Whole tone

A half tone, or semitone is, for example, C to D flat (or C sharp, notated C#, depending on the key you’re in):

A Half Tone, or Semitone

Hear A Semitone

So a scale is collection of tones and semitones. I mentioned earlier that a major scale is: tone, tone, semitone, tone, tone, tone, semitone.

The same thing applies for all of the other keys, for example D to D: tone, tone, tone, semitone, tone, tone, tone, semitone. You count the tones and  semitones from the note on which the scale starts. However, to play a major scale in D using this system, we need to play the F# (F sharp) and C# to get the same result as a simple major C scale:

D to D

Hear A D major scale

…and so on up the keyboard, i.e. this applies to every note: C, C#, D, Eb etc.

Since music is so mathematical, it has a natural order, i.e. harmony. You can write music that’s chaotic, but we hear the chaos because it’s the opposite of the harmony we’re used to.

Chords

Going back to the scale of C, it uses all of the white notes, C, D, E, F, G, A, B, 7 in total. The harmony of music is constructed by taking certain “key” notes of the scale to make “chords”. These form the “shell” of the chord, and give it its color, and are formed most commonly by taking the 1st, 3rd, 5th and then octave of the scale (i.e. same note as the root, but 8 tones higher).

So the Major chord of C would use: The root, the basis of the harmony of the chord, C, then the third note, E then the 5th note, G and then the root again but 8 notes higher, C .

Major C Arpeggio

Hear A Major C Argpeggio

A chord played in a ‘staggered’ sequence, as in the MP3 above, creates an arpeggio (sometimes referred to as a ‘broken chord’). An arpeggio is usually constructed from the key notes of a chord, for example the arpeggio above is the root, 3rd, 5th and octave of a C major chord. Once again, the same major scale arpeggio can be constructed in all of the keys, by playing the same notes in sequence.

You make it a minor scale, thereby changing the “color” of the chord completely, by flattening the third note, i.e. playing E flat in the key of C.

A C Minor Arpeggio

Hear A C Minor Arpeggio A D Minor Arpeggio So a minor D chord, for example, would be D, F, A, D. In other words, you've flattened the 3rd, and substituted F for F# (sharp): D Minor Arpeggio

Hear A D Minor Arpeggio

Every chord has a color. And you can enrich the colors by adding variation to the chord.

A chord starts out very simply, i.e. a major chord, but can become very changed by moving one note a semitone, as in the example of the minor arpeggio above. Flattening the third gives you a minor chord. As in the example above, a chord changes its color and tone most commonly by flattening or sharpening the 3rd, 5th or 7th.

The next step in changing a chords’ color is to change the 7th note, thus creating a 7th chord. Once again as in the example above, a 7th chord can be major or minor by flattening the third or 7th notes.

Here are all of the 7th chords:

Major 7

In the key of C, the Major 7th note would be B:

C Major 7th Chord

Hear A C Major 7th Chord

The Major 7th is used extensively in pop music, i.e. a major 3rd and a major 7th (in the key of C, as in the piano keyboard above, the 3rd is an E and the 7th a B). And just within this change of a chord, we start to get complexity and a pull to the harmony, i.e. the symmetry, of the music.

Minor 7

If you play a C chord with a major feel, i.e. the E (C, E, G, and B – no need to play the C again in this case since you already have it in the chord, what they call the root note), as in the “major 7th” chord above, it sounds very different than if you play the same chord but flatten the E, making the chord a minor one. This gives the chord a very “sad” feel, the pull of the major 7th against the minor 3rd:

C Minor Major 7th

Hear A C Maj Min 7th Chord

I mentioned earlier that if you flatten the 5th of a minor 7th chord, you get the blues scale:

Hear The Blues Scale In The Key Of C

Make a sequence out of this chord, a pattern of chords that relate to each other, and you get the blues.

The Blues

Let’s take a look at a classic 12 bar blues sequence. I mentioned that music has a natural symmetry to it, and this is at work when we play a song. The chords are constructed in sequence, with everything relative to the key of the song, i.e. its root. So in the key of C, all the chords relate to the key of C:

C7 C7 C7 C7

F7 F7 C7 C7

G7 F7 C7 C7/G7

Hear A Classic Blues Sequence

Some notes sound “right” when played in sequence, and have a natural pull, i.e. harmony to them. The F7 leading out of the C7, the G7, F7, C7 progression sound “right”. This is because all the chords are related to the key of C. F is the 4th note of the scale of C and G the 5th. So why the 4th and not the 3rd, or minor 3rd, i.e. part of a major or minor arpeggio for example?

The Cycle Of 5ths

I mentioned the natural harmony within music earlier. It often sounds right when chords “resolve”, i.e. they complete an equation. You can hear this at the end of a song, when there is a chord that the song “feels right” to end on. The strongest ‘root movement’ (which is what the bass is playing) is actually either down a perfect 5th or up a 4th. When you start on the second note of a key, for example in the key of C you would play a D, and move up a 4th and then down a 5th. This is called a ’2,5,1′ progression, and it’s more commonly written using Roman numerals ‘II, V, I’:

Hear an Example of a II IV I Progression

You can hear this ’2, 5,1′ progression throughout modern genre, Classical, blues and Jazz music.

You can also play the cycle of 5ths through all of the major keys. Starting on any note, the cycle will always lead you back back to your original starting place:

The triangle sign in the diagram above means ‘major 7′.

This ‘Cycle Of Fifths’ is often depicted in a circular diagram. So, once again, wherever you start, it’ll lead you back to the same place:

Cycle-of-Fifths Diagram

Hear The II V I Progression In all Keys

This MP3 plays the II V I chord progression sheet music shown above.

The Relative Minor Keys

A minor key is called a relative minor key because it has the same amount of sharp and flats as its counterpart, the relative major. Looking at the ‘Cycle of 5ths’ diagram above, we can see that for every major key, there’s a ‘relative minor’ key next to it.

And a minor key is called a ‘relative minor’ because it has the same amount of sharp and flats as its counterpart.

We can get an idea of this by just comparing 2 scales on a piano keyboard. The “relative minor” of C major is A.

As we saw earlier, the key of C has no sharps or flats:

C to C

However, when you play A to A instead of C to C, but use only the white notes, you get the scale of A minor:

A Minor

Since A major has three sharps, C, F, and G, flattening them (shown here in red) creates the scale of A minor.

Hear The Scales of C Major and A minor

The sequence of ‘tone, tone, tone, semi-tone, tone, tone, tone, semi-tone’ is the same for all of the major keys, moving through all the notes on the piano: C, Db, D, Eb, E, F and so on. And the same rules apply to the minor keys (tone, semi-tone, tone, tone, semi-tone, tone, tone: flattening the third, 6th and 7th).

Back to the blues. As I mentioned earlier, you can hear in the blues example a few paragraphs above, how the chords move and have a “rightness” to them. Chord progressions are never fixed, however. For example, the last chord of the blues progression above is a G7, a “passing chord”, which takes us back to the C7. So in the last bar there are three beats of C7 and then one of G7. However, just staying on the C7 would work just as well. Musicians often work out their own way to play certain chords and chord progressions, which are called “voicings”, i.e. how you “voice” the chords. As a singer, it helps enormously to be able to hear the chord and how the chords move within a song. You then don’t have to rigidly stick to the tune and can take more risks (check out the article “How to Ad-Lib, or Improvise” if you’d like to learn more about this).

The “colors” of chords, or chord voicing s, aren”t just limited to making them a simple major, minor or minor 7th. We saw earlier how changing just one note in a 7th chord completely changes the chord. In fact, there are 5 types of seventh chords.

7th Chords

C major 7th (1 3 5 7). Major 7th Chords have a major 3rd and a major 7th. As musical notation, this would often be written as C with a triangle after it, or C Maj7.

Dominant 7th. C7 (1, 3, 5, -7). Dominant 7th chords have a major 3rd and a minor 7th. As musical notation, this would be written as C7.

C minor 7 (1 , -3, 5, -7). Minor 7th chords have a minor 3rd and a minor 7th. As musical notation, this would be written as either C-7 or Cm7.

C-7, flat 5 or the “Half Diminished” or “Half Diminished 7th”. Half-Diminished chords have a minor 3rd a flat 5th and a minor 7th. As musical notation, this would be written as C-7 flat 5 or C with a circle and a line through it at an angle.

Diminished 7th (1, -3, flat 5 ,double flat 7th, i.e. the 6th). Fully Diminished 7th chords have a minor 3rd, a flat 5th and a double flat 7th, equivalent to the 6, i.e. the 6th note in the scale. As musical notation, this would be written as or C dim7 or a C with the Circle sign and then a 7.

C Diminished

You can play all of these chords in sequence, from the Major 7th to the fully diminished, and hear, just by changing one note at a time, that as the notes get crunched together, the chord sounds more complex:

In sequence the chords in the sound bite above are: C, C maj 7, C 7, C min 7, C half diminished, C Diminished

Suspended 4th Chord, or Sus 4. And now we get more complex. Play the 4th and the 5th (leaving out the 3rd), get what”s called a suspended 4th, or a sus 4 chord.

If you play the same chord, the sus 4, then change it to a simple major chord, i.e. moving the 4th to a 3rd, you get a classic “resolving” chord, heard a lot in Classical and Church music, for example.

Once again, one note making all the difference.

You can also sharpen the 5th, or flatten the 5th. And yet again, you can play all of these chords in sequence and hear how the harmony changes as you do so. You can keep counting up from the octave, so you get the 9th, 11th and 13th, what”s called the upper part of the chord. And each change of harmony gives the chord another name, and another color.

Modes

We’ve looked at how quickly we can reach considerable complexity from a simple scale.

We can see the possibility for even greater depth, however, when we look at “Modes”, once again used a lot in jazz. Any good musician, guitar axe heroes included, needs to have a knowledge of modes for their playing to have any real edge. In the sixties, “Modal” music became popular, when, for example, the whole tune would be written using only a few chords and a ‘modal’ approach. Often the bass player would play “the root” and the chords would change over the static base note, thus suggesting different modes, i.e. the sound of different chords played against the repeating bass note. Wayne Shorter”s “Windows” or Miles Davis”s “All Blues” or “Freddy the Freeloader” being a few examples.

Once again, we can see how simple and complex music is by just looking at the basic modes in the key of C. Some of these modes are used in modern genre music, and some, are simply, not.

By just playing the white notes in the key of C, the scale sounds very different, depending on the note we start on:

Basic Major scale: See diagram and MP3 of piano scale above.

Dorian Mode. This one is easy to remember. By playing “D to D” (i.e. just the white notes), we’re essentially flattening the F and C, making this mode akin to a simple D minor:

Phrygian Mode. This scale is E to E (again just the white notes) and sounds very sad. Composers use this scale if they want the music to sound Oriental. It’s also heard a lot in Spanish, Hebrew and Gypsy music. Once again, you’re flattening the F and G, C and D notes, the scale starting with a half-step, E to F:

Lydian Mode. This sounds almost the same as the major scale. Starting on the F and playing up the octave, once again just the white notes. The only difference is the 4th note, which should be a Bb to make it a normal major scale. By playing a B rather than a Bb you are “raising the 4th”. This was actually the “Major scale in the middle ages”, and is the basis for Gregorian chants and the like. The major scale as we know, with a flattened 4th, came about much later.

Hear The Lydian Mode

Mixolydian Mode. This has the most intricate name, but is also the easiest to recognize. Played G to G (white notes) it has a flattened 7th, and is used across the board for Rock, Blues and Jazz.

Aeolian Mode. A to A, playing the white notes. We’re essentially flattening the C, F and G. It’s also called the Natural Minor Scale.

Locrian Mode. B to B, white notes. Verrry odd to the ear, and hardly ever used.

So we can start to see the intricacies of music, everything based around a system that’s so simple it’s hard to believe such amazing complexity lies waiting to be discovered.

And now we’ve covered the basics, it’s time to move on to the next part of the puzzle: How to Read Music (link).
