In music, a quarter note (American or "German" terminology) or crotchet (British or "classical" terminology) is a note playe for one quarter of the duration of a whole note (or semibreve), and is a prominent feature in Arabic music. Quarter notes are notated with a filled-in oval note head and a straight, flagless stem. The stem usually points upwards if it is below the middle line of the stave or downwards if it is on or above the middle line. However, this may be changed if there is more than one part to differentiate between the parts. The head of the note also reverses its orientation in relation to the stem. (See image.)
