A musical note lasting one-thirty-second of a whole note, equal to half the duration of a semiquaver.
British musical term combining 'demi' (half) + 'semiquaver' (a sixteenth note). The 'quaver' part comes from Middle English 'quaveren' (to shake), describing the trembling quality of rapid notes.
Music notation is basically mathematical—a demisemiquaver is literally half of a half of a half of a half, which is why composers use this word instead of saying 'thirty-second note' like Americans do.
