Rousseau is a music notation software accessible to all (especially for musicians) that produces standard and numbered musical notation (nmn) with the sound of an Italian harpsichord. The program features playback, key and octave change, accidentals and formatting, and allows users to select a song from their iReal b library to use as a template and save as an .irb file for easy import into iReal b. This type of numbered melody notation (nmn) was created by Jean-Jacques Rousseau (1712-1778).
