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"). Thirty-second notes are notated with an oval, filled-in note head and a straight note stem with three flags or
Musical note number (and 69 is the number of semitones between C (note 0) and A). And in the opposite direction, to obtain the frequency from a MIDI note "p", the formula is defined as: For notes in an A440 equal temperament, this formula delivers the standard MIDI note number ("p"). Any other frequencies fill the space between the whole numbers evenly. This lets MIDI instruments be tuned accurately in any microtuning scale, including non-western traditional tunings. Music notation systems have used letters of the alphabet for centuries. The 6th-century philosopher Boethius is known to have used the first fourteen letters of
