Finger vibrato

There's a third kind of vibrato, and this lesson is here so you know what it is and then set it aside. Finger vibrato is a REFERENCE technique for this course — recognise the term, don't drill it.

What it is

In finger vibrato the motion comes from the finger's own base knuckle bending in and out — no forearm motion, and barely any hand motion. It's the smallest and subtlest of the three, a tiny flutter used for very fast, very narrow shimmer, or on a note too short for a full arm or wrist vibrato to bloom.

Why it's not your next step

Two reasons:

• It's genuinely advanced. It needs very loose, independent finger joints and a completely secure hand — the kind of control that comes after years, not months.
• Many teachers argue it isn't really a separate technique at all. Fritz Gearhart calls it "a result of the other two, not an independent motion" — i.e. once your arm and wrist vibrato are free, a bit of finger-joint give happens on its own, and that's finger vibrato. Chasing it directly, before the bigger motions are loose, just teaches the hand to tense.

The source course tags it the same way: "Finger vibrato... is not the next step simply because your wrist vibrato feels difficult."

What to do instead

Build a loose arm vibrato and a loose wrist vibrato (Movements B–C). The finger contribution will arrive by itself, and you'll be able to narrow and speed your vibrato for a fast passage without ever having practised "finger vibrato" as a thing.
