K.216 · I — the first solo: the flourish
The theme is out. Now the solo answers it — a rising run, a climb to the top of the hand, and a walk back down to a soft landing. This is the first bit of real display in the movement.
Bars 13–14 — the run up
How to play it
Hold A (3rd finger, E string) for two beats with a warm vibrato, then a quick turn down and back — A, G, F♯, G — all fingers on the E string, first position. A whole down-bow on the A, then small strokes for the turn.
How to play it
3rd finger to 4th finger, A to B, a light quick trill-like figure. Keep the hand still and just tap the little finger.
Bars 14–15 — up to the top: a shift to third position
How to play it
Shift up: the hand moves so the 1st finger sits on A (an octave above the open A) and the 3rd finger reaches high C. That's third position. The broken-third figure C–A–C, twice — bounce lightly between 1st and 3rd finger on the E string.
How to play it
Start in third position — C, B, A, B, A on 3rd–2nd–1st fingers — then let the hand slide back down the E string with the scale: G, F♯, E land in first position. The shift happens inside the run; don't stop for it.
Bars 16–17 — back down
How to play it
Now on the A string, first position. D (3rd finger) held, lift to E; then C (low 2nd finger) held, up to D. Two little sighing figures. Slow the bow into each long note.
How to play it
Same shape, lower: B to C, then the open A up to a stretched 4th-finger E. The phrase is winding down — keep it light.
Bars 18–19 — landing
How to play it
A grace note flicks down into G (3rd finger, D string), held three full beats — a long, calm bow with vibrato. Then a small B–A on the A string to close.
How to play it
A short, clean G. Then stop the bow and count the rest — the next tutti is coming, and you re-enter at 'C'.
