How do I read the chord diagrams?

The coloured keys are the notes of the chord. Every key carries its name and octave (C4 is middle C), and each coloured key also shows its degree in the chord: 1 is the root, 3 the third, 5 the fifth, ♭7 the minor seventh.

What is a chord inversion?

An inversion plays the same notes with a different one at the bottom. In the first inversion the third is lowest, in the second the fifth, and in the third (for four-note chords) the seventh. Inversions keep your hand close when you move between chords.

Why C♯ minor but D♭ major?

Every black key has two names. Each chord is spelled the way that reads most simply: D♭ major is D♭ F A♭, while C♯ major would need an E♯. Every page also gives the other name, which uses the same keys.
