Let me explain it to you then. A semitone, which can also be refered as a half tone or half step, is actually the smallest of the musical intervals and is common for it to be used in tonal music from the west
A semitone is a half tone and is called the most dissonant when sounded harmonically. It's a bit complicated I would say but it's common in Western tonal music.
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 ? 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 well, you know more than I do. I don't even know what a semitone is.
