How to use this

Every major and minor key is built from seven chords — these are the ones that naturally sound good together. The Roman numerals (I, ii, iii…) show each chord's role, and stay the same in every key, so once you learn a progression like I – V – vi – IV you can play it anywhere just by sliding to a new key.

Want to solo over these chords? Head to the Scale Library — the major scale of your key (or its relative minor pentatonic) will fit right over the whole progression. Look up any chord's shapes in the Chord Library.
