Change the duration of a note
Notes duration basics
Changing the head, adding a flag, or remove the stem from a given note, alter the duration of this one. Usually, the Quarter Note, corresponds to one beat music note. A Half Note will multiply its duration by two and a Hole Note by four. On the contrary, adding a flag divides the duration of the quarter note by two.
Changing the duration of a note or rest on Flat
Select the note or rest that you want to modify, then go to the Note toolbar. Choose any duration you want, from the whole note to the sixty-fourth note. The tools to change the duration of a note or a rest are unified and have the same icons in the toolbar so you can change the duration before or after adding a note.
