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.

While composing, Sibelius synchornizes the master score and every instrument part automatically, eliminating repetitive edits across the arrangement.
Rework arrangements effortlessly
Swap instruments, transpose passages, and reshape orchestrations for new ensembles while keeping the arrangement intact.
Expand sketches to scores
Use Explode and Reduce to turn piano sketches into full orchestrations or condense ensembles into playable piano scores.
Format as you write
