I'm not a musician and I have a musical and Linux software question.
I once saw something in a Mac music scoring app where running your mouse up and down the scale on the little horizontal lines would actually sound each note in turn. Unfortunately I don't remember what the name of the Mac program was, although it was before the days of the iMac.
What is that sort of 'note sounding' behavior called in music software? Are there any Linux programs that do that?
Thanks in advance if you can name the Mac program, the note-sounding behavior or suggest a Linux program that does this. I am completely lost.
