Spiccato
Spiccato is the first off-string stroke — the bow leaves the string between notes, bouncing. It's a LATER stroke: a real, even spiccato needs a relaxed, organised bow hand and a sure feel for the bow's balance, which come from months of the on-string strokes first. The job here is to know what it is, hear it, and take the one honest first step toward it.
What makes it spiccato
You give an individual impulse for every single note — it's a controlled stroke, not one that runs on its own. The bow is dropped or placed onto the string and lifts off again, note by note, at or just below the middle of the bow. (Détaché lives just above the middle — a handy contrast.)
The catch: even though it bounces, each note still has to ring. A bounce that only clicks, with no pitch, is a failed spiccato. You want the crisp bounce and a clear note.
The honest on-ramp — the brush stroke
Don't start by trying to bounce. Start with a brush stroke: a broad, gentle, barely-off-the-string stroke — more horizontal than vertical, with some length to each note, singing rather than crisp. A loose arm, a flexible hand, a small "give" at each note. It's how most methods introduce the feeling of an off-string stroke without the difficulty of a true bounce.
How to play it
Lower-middle of the bow. Light and long, more of a horizontal sweep than a drop. Let the wrist and fingers stay soft — if the bow starts to bounce a tiny bit on its own, fine, don't fight it.
The next step, later: play a light, fast détaché in the middle of the bow and gradually stop controlling it so hard — let the bow start to bounce by itself. Spiccato is basically "détaché that you stopped holding down."
Try it
Try
Just the brush stroke for now. Open A, sixteen light broad strokes in the lower-middle of the bow, arm loose, each note a little separated. Then the same on F♯. If the strokes are even and your hand stays soft, that's a real Stage-5 achievement — the bounce will come later.
The usual mistake
Trying to force a bounce with a stiff hand — you get an uneven scrabble, some notes loud, some
missing, and a tired arm. Spiccato comes out of looseness, not effort. And reading every
dotted note as "off the string": in a slow or moderate passage, dots mean on-string staccato
(staccato), not spiccato.
