Working the beat
Note length: where a sound starts and ends
Written by a guitar teacher who runs a private studio in Japan. Published October 2, 2026
So far we have mostly dealt with the position of a sound — when it starts. But when you think about rhythm while playing an instrument, the end of a sound matters just as much as its start.
In the diagrams below each cell is half a beat: ● is where a sound starts, ━ is where it keeps sounding, and · is silence (the last cell is beat 1 of the next bar).
Start, note value, end
Start
Just what it says: the moment the sound begins. Until now, this series has been about sounding at the moment you intend — at a position in time.
Note value
A note value is the length of time given to a note or a rest. For a note it is the span in which the sound may ring; for a rest, the span in which nothing should sound.
A value of one beat lasts one beat. So “play one beat from beat 1” means, as a rule, sound on beat 1 and end the sound on beat 2. The “distance between one mark and the next” from Thinking in clock time shows up here as the length of a sound.
End
The end of a sound is the moment it falls silent, or the moment a new sound starts and cuts off the one that was ringing.
Without attention to where and how sounds end, the playing will not be rhythmically correct. Yet with some instruments and some markings, it seems not to matter whether you think about the end at all. That seems to make the whole idea harder to grasp.
The trap of sounds that decay
Some sounds start to decay the moment they begin and cannot be sustained. The very short sounds common in percussion die away before the note value is over, so there is no need to think about or control their end. This is the situation where it seems fine to ignore the end.
But if you never think about the end, you lose the sense of note value itself. Beats and divisions then creep early or late without your noticing, until you find yourself playing at completely wrong moments.
Sounds to hold, sounds to stop
On an instrument whose sound lasts — or can be made to last — longer than the note value, you need to control the end.
If the sound can last longer than the value, in practice you do not need to count the length from the start; just keep it going until the next instruction.
However, most instruments with long sustain only sustain if you keep working at it: the breath of a singer or wind player, keeping a key down, keeping a string fretted, the movement of a violin bow. Let that slip and the sound ends short of its value, at a moment you did not intend, which does not leave a good impression. Here you keep the sound going for its full value while preparing the next one.
The opposite case is the sound that rings on without being asked to — open guitar strings, cymbals. Unless you think about when to stop them, unwanted sound goes on and on.
Staccato
Staccato deliberately shortens a sound that could be held for its full value. Classical music specifies it in more detail; in popular music it is often left to the player. You can aim to stop each sound as soon as possible after it starts, or you can aim at a definite stopping point, such as half the note value.
What about instruments that play several sounds at once?
On instruments where one player controls several sounds — keyboards, string instruments, a drum kit — each sound has to be controlled to its own note value.
On any instrument, the starting point is knowing, for every single sound, where it starts and how far it lasts. The more sounds overlap, the harder it is to manage their ends, but the idea is the same as for a single sound.
Summary: back to position and length
This series has moved from pulse to beat, meter, division, swing and finally the length of sounds. All of it has really been about two things:
- Position: when a sound starts (on which beat, at which point of the division).
- Length: how far it lasts (at which point it ends).
When we plan with a clock, we think “from what time, for how many hours” without a second thought. Playing is the same. Know where every sound starts and how long it lasts, prepare before you play it, and the performance becomes a schedule you can reproduce.
The reference for all of this is the player’s own inner beat. The circular metronome is a guide for growing that inner beat. Start by playing along with the dial, remove the guide little by little, and aim to play on your own beat alone.
