MuseScore is a free scorewriter for Windows, macOS, and Linux, comparable to Finale and Sibelius, supporting a wide variety of file formats and input methods. These software programs are licensed under the GNU Public license (proof on request) no copyrights or trademarks have been infringed.
MuseScore's main purpose is the creation of high-quality engraved musical scores in a "What-You-See-Is-What-You-Get" environment.
t supports unlimited staves, linked parts and part extraction, tablature, MIDI input, percussion notation, cross-staff beaming, automatic transposition, lyrics (multiple verses), fretboard diagrams, and in general everything commonly used in sheet music.
Style options to change the appearance and layout are available, and style sheets can be saved and applied to other scores. There are pre-defined templates for many types of ensembles. Functionality can be extended by making use of the many freely available plugins.
MuseScore can also play back scores through the built-in sequencer and SoundFont sample library. Multiple SoundFonts can be loaded into MuseScore's synthesizer. There is a mixer to mute, solo, or adjust the volume of individual parts, and chorus, reverb and other effects are supported during playback.
