Thirty-second note connected with a beam. Similar rules apply to smaller divisions such as sixty-fourth notes. A related symbol is the thirty-second rest or demisemiquaver rest (shown to the right), which denotes a silence for the same duration. Thirty-second note In music, a demisemiquaver (British) or thirty-second note (American) is a note played for of the duration of a whole note (or "semibreve"). It lasts half as long as a sixteenth note (or "semiquaver") and twice as long as a sixty-fourth (or "hemidemisemiquaver").

A♭ (musical note) A♭ (musical note) A (A-flat; also called la bémol) is the ninth semitone of the solfège. It lies a diatonic semitone above G and a chromatic semitone below A, thus being enharmonic to G, although in some musical tunings, A will have a different sounding pitch than G. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the A above middle C (or A) is approximately 415.305 Hz. See pitch (music) for a discussion of historical variations in frequency. A/G is the only note to have only one other enharmonic.
