Major (Ionian) · C · Piano
The C Major scale is C D E F G A B — formula 1 2 3 4 5 6 7, step pattern W–W–H–W–W–W–H. Use it over Cmaj7: it is the scale for the I chord (maj7) and any major-key tonic; the default over Imaj7 in a ii–V–I. Below, every note is marked on the two-octave keyboard; press play to hear it on a synthesized piano while each note lights up, or tap any key to sound that note.
