Ear Training Play It By Ear HN is a game that teaches you to recognize any music notes you hear. You can customize the music notes to learn or improve, the number of notes to play, the number of Lives, the background color, etc. The cartoon images for each good note are optional. You can play in G (Treble Clef) and F (Bass Clef) both with alphabetical (A B C...) and syllabic (DO RE MI) musical notation.
