Many musical acts have been ridiculed for only playing the same three chords over and over. “Three-chord” rock music is practically its own genre. The I-IV-V major key chord progression is even considered the “standard” blues progression. Within that construct, there are only 12 basic “notes” or tones in the musical spectrum: A, Bb, B, C, C#, D, Eb, E, F, F#, G, and G#.
