What is a MUS file?

The .mus file is a legacy Finale Notation File format used by the Finale software, a popular music notation program developed by MakeMusic. This file type is designed to store musical scores, allowing composers, arrangers, and musicians to create, edit, and print sheet music. The .mus format holds data such as notes, rests, tempo markings, key signatures, time signatures, and other elements of a musical score.

The key features of the .mus file include:

  • Editable Music Notation: Allows users to work on sheet music, making adjustments to every element of a composition.
  • MIDI Integration: It can store MIDI data, enabling playback of the composition using synthesized instruments.
  • Compatibility: Older versions of Finale use this format, but recent versions of the software have shifted towards the .musx format for better support and functionality.
