NoteWorthy Composer (NWC) is a proprietary scorewriter application made by NoteWorthy Software. It is a graphical score editor for Microsoft Windows computers (from Windows 95 to Windows 10), and also works on PCs under Linux with Wine. Version 1 of NWC was released in October 1994, and Version 2 in September 2008. The current version is Version 2.75.
NWC is intended for the creation of sheet music, but it can also import and export MIDI and Karaoke files and can export graphical WMFs. The user interface works either from the keyboard or the mouse. Visual results are immediate, and audible results can be heard at any time. Notes can also be entered by playing on a MIDI device, when configured. In version 2, the notes can be heard as they are entered.
The NWC file format is undocumented and facilities to convert it into documented formats are limited. Version 2 of NWC introduced a textual version of the files, NWCTXT. These can be used for conversion to many other formats, including LilyPond.
