 MuseScore is an Open Source (GNU GPL) music notation software that runs
 on all platforms supported by Qt5 (GNU/Linux, MacOS X, Windows), and is
 available in over forty different languages. It features an easy to use

 beautiful, rivaling commercial offerings like Finale and Sibelius.

 .
 Most elements in MuseScore are laid out automatically on a “virtual note
 sheet”, with a near professional-quality layout engine, but can also be
 positioned manually, giving you total control of every score element’s
 position. The capabilities of MuseScore can be extended via plugins and
 extensions, and the growing repository on musescore.org contains many
 plugins submitted by users and an active development team.
 .
 MuseScore includes a set of sounds that reproduce common instruments (as
 defined by General MIDI) without taking up a lot of disk space or memory
 providing full orchestral and band sounds (with the Drumline extension
 installed this includes marching percussion). The general (non-Drumline)
 sound font is available as musescore-general-soundfont Debian package,
 if you wish to reuse it with other synthesisers.) You can also load any
 sound font you prefer for a wider variety of sounds or for more realism.
 .
 MuseScore can import and export MIDI and MusicXML files, and it can also
 import from Capella and several other programs. MuseScore can export to
 PDF, PNG, and other graphic formats, to WAV and other audio formats such
 as OGG Vorbis and MP3, or to GNU Lilypond for an alternative layout and
 print option.
 .
 MuseScore can upload scores to musescore.com, a score sharing site, and
 send scrolling sheet music videos to YouTube. In addition to the desktop
 software, you can rehearse “on the go” with MuseScore mobile apps (which
 do not support note entry, but many advanced playback functions). Note
 that all of these are commercial or otherwise non-free offers optionally
 integrated with, but not part of, the Free notation program. Scrolling
 video scores feature the notes highlighted in the score as they sound —
 and highlighted on a virtual piano keyboard below.
