Stage 7Vibrato & expressionLesson 20 of 27 · The bow

Tone colour as a choice

Stage 3 taught you the colour words — sul tasto, sul ponticello, flautando, con sordino. Stage 5 taught you the five lanes between the bridge and the fingerboard. This lesson is about using them as a palette — picking a colour because it fits the character, not because the page told you to.

The colours you have

Where the bow isThe colourFits
Lane 1–2, near the bridgefocused, bright, full of corea fanfare, an arrival, intensity
Lane 3, the defaultplain, direct, "normal"most things
Lane 4–5, near the fingerboard (sul tasto)soft, veiled, hollow, distanta memory, a lament, a pianissimo
Right against the bridge (sul ponticello)glassy, thin, metallic, eerietension, the sinister, a special effect
Light and fast, over the fingerboard (flautando)flute-like, weightlessa shimmer, a halo
Mute on (con sordino)hushed, grey, a different instrumenta nocturne, something withheld

And the strings themselves are colours: the same written G is dark and thick on the G string, bright and clear on the D string. Choosing which string to play a note on is choosing its colour.

How to play it

For the sul tasto version: bow slower and lighter, moved toward the fingerboard, almost no arm weight. Narrow the vibrato right down or drop it. It should sound like it's coming from another room.

A quiet falling-then-rising phrase. Play it once warm and direct in lane 3. Then play it again over the fingerboard, sul tasto — soft, veiled, far away. Same notes; the second one sounds like a memory of the first. Playback gives you the plain version only.

The choice comes from the character

You don't reach for sul tasto because it's an interesting effect. You reach for it because the phrase is a whispered memory and a covered colour is what a whispered memory sounds like. The character decides (next lesson); the colour serves it.

Try it

Try

One phrase you know, three colours: normal (lane 3), sul tasto (veiled), sul ponticello (glassy). Then decide: which colour would you give a lullaby? A ghost story? The triumphant last line of a hymn? Play the phrase in the colour you chose for each.

The usual mistake

Living your whole playing life in lane 3 — one colour, forever — so every piece sounds like the same voice reading different words. The opposite mistake is treating the colour words as effects to show off, dropping a sul ponticello into a tender phrase because you can. Colour is a choice in service of a character, not a trick.
