GNU Solfege is a free, open source program designed to help musicians practice and improve their ear training and music theory skills. It is designed to be used in both educational and recreational settings. The program is available for Windows, Mac, and Linux systems and can be downloaded from the official website. The app includes a variety of drills and exercises to help users with their ear training, such as rhythm and pitch exercises, dictation, and interval comparison. It also includes exercises for music theory, such as chord and scale recognition, key identification, and recognition of key signatures. The program also includes a metronome and a recorder for users to record and playback their progress. Users can create custom exercises to practice and develop their skills. They can also view their progress from the built-in statistics page. GNU Solfege also allows users to share their scores with other users online.
