A sixty-fourth note is one of the smallest musical note values in Western music notation, worth 1/64 of a whole note. It is also known by a variety of synonyms, including hemi-demi-semi-quaver, hemi-semi-demi-demi-semiquaver, quasihemidemisemiquaver, or semidemisemiquaver. In jazz notation, it may be called a sixty-fourth note or a semiquaver. In French, it is called a double croche. In German, it is referred to as a sechsundsechzigstelnote. Whatever the name, this tiny note value requires great precision and speed to play well and is commonly used in fast, complex pieces of music.
