The agogic accent

You can stress a note without playing it louder — by holding it a hair longer than written. It's called an agogic accent (agogic = to do with timing, as opposed to dynamic = to do with loudness), and it is probably the most-used expressive device in all of music. It's also completely invisible on the page.

How it works

You lengthen the important note slightly, and you borrow that length from the note right after it — which gets a touch shorter. A tiny stretch here, a tiny squeeze there, and the bar still adds up. The listener doesn't hear "wrong rhythm"; they hear emphasis.

How to play it

The stretch is small — the D is maybe a fifth longer than written, the C a fifth shorter. Bow keeps flowing. If it sounds like a dotted rhythm, you've overdone it.

A rising line to the D at the top of bar 1. Give that D a little extra length — lean into it — and take that length back off the C that follows it. Same notes, same loudness; the D now sounds stressed. Playback is exactly even; the lean is yours to add.

It's how speech works

You stress a word by lingering on it — "that's the one" — not only by saying it louder. Leopold Mozart said dynamic shading on the violin "imitates the inflections of speech"; the same is true of timing. A phrase read with no agogic shaping sounds like a robot reading a sentence with every word the same length.

Where to use it

  • The first note of a group or a beat — a gentle lean marks where the pattern starts.
  • A dissonance resolving to its consonance — linger on the tension, then release.
  • The peak of a phrase — it often wants both an agogic and a dynamic lean together.
  • A surprise — an unexpected note or harmony gets a moment of extra time to register.

Try it

Try

Play a one-octave G major scale, and lean (lengthen) every third note — G, B, D, F♯, A… — repaying each stretch from the note after. Then play a phrase you know and find the one or two notes that most want the lean. Usually you'll feel it before you can explain it.

The usual mistake

Overdoing the stretch until the listener hears an actual change of rhythm — a lean becomes a limp. It should be felt, not identified. The other mistake is stacking a hard dynamic accent on top of every agogic one, so nothing is subtle — sometimes the only stress a note needs is a little extra time.
