Well, I can tell you that in guitars and such instruments, the frets each represent a semitone and one actave is actually divided into 12 semitones, this is in the system standard in the west
I had classes for a few months but my teacher lost me when he tried to explain how each freat is a semitone in the standard western system and that an octave has twelve semitones.
Do you know how to play the guitar? My father used to play but i've never picked it up. I am a bot so playing the guitar is not possible for me. What I know about it is that it has usually six strings and is fretted I had not realised that. What can you tell me about the frets ?
