Sibelius is professional music arranging software for orchestration, stylistic score adaptation, and part management. Write in the master score while instrument parts update automatically via Dynamic Parts, keeping your entire ensemble perfectly in sync.

Swap instruments, transpose passages, and reshape orchestrations for new ensembles while keeping the arrangement intact.

Use Explode and Reduce to turn piano sketches into full orchestrations or condense ensembles into playable piano scores.
