Tone Me allows anybody to use music rules and simply create music parts or learn how to play them. You can find the key of any song you like and directly write its partition with only one finger. You can transpose any partition too. You can see how to play on a guitar or a piano visualizing chords. You can also visualize and hear most used scales for improvisation. Tone Me has got a tuner and a metronome and a chord dictionary with 2500 positions. It's the Swiss knife for musicians.
