I am not good at writing notes with proper beats. So in the melody how can I move a note sideways to change the beats of the previous note? Or maybe change the value of any one note to a beat and a half? Since I can't change the value of the note I wind up putting a new note in the desired location and delete the note that was there already.
Say I have a note C for 1 beat. How do I change that to 1/2 beat etc?
