I need to kown all 8 letters music instruments name.

Answer 1

Do you want the letter designations of the notes they play? Or the names of instruments? (In both cases there are more than eight)

There are 12 notes in a full octave of the diatonic scale, counting half tones.

Answer 2

Try to clarify your question, if possible. Could it also be the scale one might play? C, D, E, F, G, A, B, C
