Wait, the use of the subdivide depends upon the feel of the song as well as cadence, the "pulse" of a particular tune and, sometimes, the player's internal time clocking.

Use of "One-A-and-Ah" subdivides each beat into 4 (16th notes) instead of 2 (8th notes) and should be used when needed. For example, when scanning the sheet before attempting to play, you happen to see strings that include 16th notes.

Use of that 16th mental subdivision technique may also come in handy for certain times when there are mostly 8th notes in the chart, as well, doubling up on your internal subdivisions of the beat can help keep the time of your internal clock more accurate.

With practice at the thing, eventually you may be pleasantly surprised to find that you can internally count the 32nd note subdivisions as well. This is just like the clock or wristwatch design that yields more accuracy and precision from dividing each Second up into smaller and smaller but equal duration events.
