I need to kown all 8 letters music instruments name.
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.
Try to clarify your question, if possible. Could it also be the scale one might play? C, D, E, F, G, A, B, C
