Sciolto
"Unbound" – free and loose in performance.
What it means
Sciolto is an Italian performance direction meaning literally 'loosened' or 'unbound.' It calls for a free, relaxed delivery that does not adhere strictly to a rigid meter or a tight binding of the notes.
The term is thus close in meaning to phrases like 'free in performance' and is often used where a passage should sound less tightly bound and more declamatory.
Musical use
Sciolto appears frequently in virtuosic instrumental music, for instance over fast, nimbly played runs or passages that, despite their technical demands, should sound not heavy or rigid but agile and unforced.
Sciolto should be distinguished from legato, which denotes a smoothly connected execution of the notes, whereas sciolto refers more to the overall character of the delivery — loose, free, unforced — without necessarily prescribing a particular articulation.
Performance practice
Play sciolto passages with a light, springy touch, without losing the underlying rhythmic structure. Avoid a too rigid, metronomic delivery, which would contradict the required loose character.
