Below is the complete full color map of C Major. The colors let you see at a glance, all the root notes, and which notes are the same, and which ones are an octave apart. This is explained in the following pages. Click on the All Notes - No Color button to see all the notes. Then click on Piano Fretboard to see the sharp notes (like the black piano keys). If we take out the black notes, we are left with the key of C Major. The black notes form a pentatonic scale.
