The Process of Sub-Division
Default 2
The chart below shows how Note Durations Are Divided and then Divided Again.
Default 4
1 Whole Note = 2 Half Notes = 4 Quarter Notes = 8 Eighth Notes = 16 Sixteenth Notes
In theory, the process of sub-division can go on forever!
32nd Notes, 64th Notes and further sub-divisions do occur, however the tempo of the music would need to be extremely slow so that the notes would have ample time duration to be audible. Commonly, Eighth Notes and Sixteenth Notes are the shortest/quickest notes that you will come across.
Default 8
Default 9
