Songwriting For Beginners: ‘Just Enough’ Music TheoryBy Jeff Oxenford • Category: How To Write Songs, Songwriting Articles

Question: How do you stop a guitarist from playing?
Answer: Put music in front of him.
That’s me. I can’t read music and I doubt I ever will. However, over the last three years, I’ve learned just enough about music theory to be dangerous. What I’ve found is that by understanding some basic concepts, I’ve been able to find that next chord I was always searching for.
The first step in understanding is that most songs are played in a single key and that the chords in the come from that key. The formula (i.e. what order) you use for the chords is what make up the song. For example, blues often uses the 1, 4, and 5 chords. If you’re playing blues in E, the chords are E, A, B (or B7). The blues progression in the key of C, uses C, F, and G.
If you can understand the table below, you’ve got the majority of theory you need.
|1 (root)||2||3||4||5||6||7||8 (root)|
|Major||minor||Minor||Major||Major or Dominant||Minor||Diminished||Major|
Here’s how to understand this table:
Guitar frets are in half (H) step intervals. In other words, moving up one fret is moving up a half (H) step. Moving up 2 frets is a whole (W) step.
Notes and intervals
On a guitar, the open string and the 12th fret on the same string are the same note (just different octave). If you look at the A string, the notes are:
|Â NOTE||A||A# or Bb||B||C||C# or Db||D||D#orEb||E||F||F#orGb||G||G#OrAb||A|
To go from A to B is a whole (W) step. To go from A to A# (or Bb) is a half (H) step.
Also, note that for B to C and E to F, there is only a half step. There is no B# (Cb) or E# (Fb).
The major scale has the following intervals, W W H W W W H. (do, rae, me fae, so la, te, do)
Applying this formula, the notes in the A major scale are: A, B, C#, D, E, F#, G#, A. As seen on the guitar the A scale looks like:
Practice tip – On any string of the guitar, apply the formula W, W, H, W, W, W, H. In other words pick the string: Open, 2, 4, 5, 7, 9, 11, 12. You’ve just played a major scale.
Numbers for the Notes
We describe the notes in a scale by their numbers (1 – 8).
When your playing in the Key of A, A is the 1 note, B is 2 – You get the idea.
Chords in the major scale
To find chords that will work in the key of A, take the root notes from the scale and use the A chord type A from the table below:
|Major||minor||Minor||Major||Major or Dom||Minor||Diminished||Major|
The 1, 4 and 5 chord are major chords (A, D, E).
The 2, 3 and 6 chords are minor (Bm, etc.)
The 7th chord is diminished
Below is a listing of the chords in the major scale for all keys.Â Use the table by following a row:
Practice tip: Take one row and play the chords in order. It should like the major scale. Then try the 1, 4 and 5 chords. Move to another row and try the 1, 4 , 5. It should sound pretty familiar.
How do you use this in Songwriting?
Most songs in folk, rock and blues primarily use combinations of the 1, 4, 5 chords. The 6 and 3 are used often and sometimes the 2. The 7 chord (diminished) isn’t used as often, but it does have a very distinctive sound.
*(Other books use roman numerals, so be ready to see I, IV, V).
For example: The formula for 12 bar blues is Blues in A – the formula is 1,1,1,1,4,4,1,1,5,4,1,5 (each played for a four count).
