What is a MUS file?
Musical notation file from Finale software
MUS files are most commonly used as music notation files that have been created by Finale Software (MakeMusic’s flagship musical notation program). Finale allows creators and producers to compose and publish music files and their associated metadata. MUS files are very similar to MIDI files, but they can contain extra metadata information. They usually only have notes, but do not contain any actual audio data. There are some other MUS files that may contain voice data.
