Half-time (music) each measure (a whole note) is divided in two by the bass drum (half note), each half is divided in two by the snare drum (quarter note, collectively the bass and snare divide the measure into four), and each quarter note is divided in two by a ride pattern (eighth note). "Half"-time refers to halving this division (divide each measure into quarter notes with the ride pattern), while "double"-time refers to doubling this division (divide each measure into sixteenth notes with the ride pattern). A classic example is the half-time shuffle, a variation of a shuffle rhythm, which is used
Symphony No. 5 (Vaughan Williams) minims in a fast 3/4 time, then minims for four bars, which create hemiolas and then crotchets.
