Q: If you wrote music for something that only supported 3 notes at the same time, which notes of a chord would you include or exclude?
A: for example, if i were doing 'twinkle twinkle little star' in the key of C, for the first note ("twink") i would use notes C, E, and G. the notes i would exclude from that chord, for example, would be F#, G#, and others
