The stem support the hook and determine some note durations. The stem (or tail): If the stem points up from a note head, the stem start from the right side of the note, but if it points down, it start from the left. The note-head whose position on the stave actually sets its pitch, can be open (white) or closed (black). To determine the duration of a note, each note sign is composed of three distinct parts: The note-head, the stem (or tail) and the hook (or flag).

Music notes have a pitch but also a duration.
