A thirty-second note (also called a demisemiquaver) represents the duration of an eighth of a beat in a 4/4 time signature.
It is identified on sheet music by a filled-in oval notehead at the base of a single straight stem, with three flags. When thirty-second notes appear below the middle line of the staff, they’re drawn with stems to the right of the notehead, facing up. If they appear on or above the middle line, they’re drawn with the stems to the left, facing down. When multiple thirty-second notes are played next to each other, instead of flags, the notes are beamed together.
Practicing thirty-second notes
As the name suggests, a thirty-second note is played for 1/32 of the duration of a whole note. It lasts an eighth of the duration of a quarter note, a quarter of the duration of an eighth note, and half of the duration of a sixteenth note.
