What is the range of eight musical notes?

It would be more accurate to refer to the eight tones (or pitches), because notes refer to duration. Also, the full set of recurring tones in Western Music number twelve. I believe you are looking for the eight white keys on the keyboard, which correspond to the letters C, D, E, F, G, A , B. The full complement of notes are as follows: C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab, A, A#/Bb, and B. Any notes with two names can be referred to by either letter depending on the circumstances and represent the black notes on the keyboard.
