Have you ever wanted to compose music on Android? Now you can! Maestro is primarily a music notation editor, but includes a pitch pipe and metronome as well. With the notation editor, you can drag and drop notes directly onto the staff and then have the app play your composition back to you. You can also change the key signature, time signature, and clef, and choose the instrument you want to hear played. It’s fast, fun, and easy to use. Maestro is currently in beta testing, and we would appreciate your feedback.
