What vibrato is · From Zero to Mozart

Vibrato is a small, regular wobble in the pitch of a held, stopped note — the shimmer you hear in a singer's long tone, or under a violinist's sustained note. It's made by rocking the fingertip on the string. It is expression, not correction, and — this matters — there is no symbol for it. Nothing on an ordinary part tells you to vibrate or not. You hear the music and you decide.

Where it lives on the page: nowhere

Look at a single long note. Vibrato would make it shimmer — but on the page it's just a notehead. No wavy line, no tr, no mark. (You met this back in Stage 2: a shimmering finger never adds noteheads — if you see extra notes, it's rhythm or a double stop.)

40 bpm

One long B — A string, first finger. This is a note a player would very likely vibrate. Nothing on the page says so. Playback gives you the plain, dead-steady note; the shimmer is the one thing this course cannot play for you.

Vibrato needs time and a stopped note. Short notes have no room to wobble; open strings have no finger on them to rock. So it lands on the long, fingered notes of a phrase:

72 bpm

A phrase that twice arrives on a long G (D string, 3rd finger). Those two held Gs are where vibrato would live. The short notes between stay plain — no time, no need.

Hear it — you'll have to go outside the site

The playback engine can't produce vibrato, so listen for it in a recording. Two clear examples: the long opening notes of Massenet's Méditation from Thaïs (try Itzhak Perlman's recording), and the sustained melody of Saint-Saëns' The Swan. In both, every held note is alive with a slow, even shimmer — that's vibrato doing its job.

The cue you'll be taught, and what actually happens

These are two different things, and it's worth keeping them straight from the start.

The cue: start with your finger on the note, exactly in tune, and rock it backward — toward the scroll — which flattens the pitch a little, then return to the note. The in-tune pitch is the top of the wobble. You never reach above it. Every teacher says this, because reaching above an in-tune note just sounds sharp.

What the string actually does: once vibrato is fluent, the fingertip rocks both sides of wherever it settles, and your ear takes the pitch as roughly the average of the wobble — in fact a note with vibrato sounds a hair lower than a dead-steady note in the same spot. So a good player's average pitch ends up sitting slightly below the nominal note — which is exactly what "roll back from the note" produces. The cue and the acoustics agree; they're just describing different things (what you do, versus what the string does).

Try it — no bow

Try

Put your 1st finger on B on the A string, in tune. No bow. Rock the fingertip slowly back toward the scroll and forward to the note — big and slow, a clear dip and return, maybe once a second. Just feel the pitch fall away from B and come back to it. That backward-and-return is the whole motion; everything else in this stage is making it smaller, faster and looser.

The usual mistake

Trying to make the wobble go above the note as well as below — it comes out sharp and nervous. The pitch is a ceiling. The other mistake is starting to vibrate before the note is in tune in the first place (the next two lessons are about exactly that).
