A time signature is presented as two pieces of data, not a fraction: the top roughly counts beats per bar, the bottom names the beat unit (4 = quarter, 8 = eighth). Simple time subdivides by two (4/4, 3/4, 3/8); compound time subdivides by three and is identified by top number > 3 and divisible by 3 (6/8, 9/8, 12/8). Examples played include 4/4 (Thriller), 6/8 (Liberty Bell), 12/8 (Moonlight Sonata) and a mixed-meter composer example.
