It lasts half as long as a sixty-fourth note. It has a total of five flags or beams. Since human pitch perception begins at 20 Hz (1200/minute), then a 128th-note tremolo becomes a single pitch in perception at quarter note ≈ 160 bpm. A single 128th note is always stemmed with flags, while two or more are usually beamed in groups. Notes this short are very rare in printed music, but not unknown. One reason

Time signatures indicating "two" beats per bar (whether in simple or compound meter) are called "duple meter", while those with "three" beats to the bar are "triple meter". Terms such as "quadruple" (4), "quintuple" (5),
