How To Subdivide The Beat

by Tim Lake

sub-dividing the beat - on jazz drumming Once you understand which note on the stave stands for which part of the drum you, you then have to understand the rhythmic values of each note - note values, that is how to sub-divide the beat. In this post I will briefly explain and show you the sub-divisions of the beat.

 

The first note to understand is the whole note (semibreve for us Brits). In 4/4 this last for a whole bar, and so we count the four beats for each note.

Next, the half-note (minim), which is half a whole note. So two half notes equal one whole note and we count each note as two beats.

Now we get to the all in the all important quarter-note (crochet). In fact this is what we’ve already been counting, 1 2 3 4. This is our pulse beat, and it is this note that we are primarily going to sub-divide.

Halving the value again we get the eighth-note (semi-quaver). These can be counted as I and 2 and 3 and 4 and.

Things now get interesting. The next sub-division doesn’t divide the note in halve again, but into three! This is the triplet and it is hugely important for jazz drumming and understanding swing. Count it as 1-trip-let 2-tripl-let 3-trip-let 4-trip-let and make sure the spacing is even.

Going back to eight-notes and halving them we get, yes you’ve guessed it, the sixteenth note (semiquaver). Count these as 1-e-and-a 2-e-and-a 3-e-and-a 4-e-and-a.

Dividing triplets in half we get the sixteenth note triplet.

And finally dividing sixteenth notes in half again, we arrive at the thirty-second note (demi-semiquaver).

There are a few more, I have skipped quintuplets and septuplets for example, but these are the most important and the ones that you will come across most often in drum notation, and on this site.
