How To Understand The Music Theory Behind These Guitar And Piano Jazz Chords Charts

We will play all these jazz chords from the root note of C, so you won’t have to worry about transposing these shapes… yet! Though, to master Guitar And piano jazz chords (and jazz piano And Guitar more broadly), you’ll want to take these 15 jazz [Guitar And piano] chords through all 12 keys.

Also, we’ll give numeric formulas for each chord based on the distance away from the root note, which is C in this case. These numeric formulas are based on the twelve tones in the octave. We can build the C major scale using this formula, and it looks like this:

C – D – E – F – G – A – B – C
rt. – 2nd – 3rd – 4th – 5th – 6th – 7th – 8th

Therefore, a C major triad would look like this: [rt. – 3rd – 5th], and a C major 7th chord would look like this: [rt. – 3rd – 5th – 7th]. We use (#) or (b) to denote pitches outside of C major for alterations to the numeric formula.

So, dominant chords are spelled like this: [rt. – 3rd – 5th – b7th] and minor 7th chords are spelled like this: [rt. – b3rd – 5th – b7th].
