Performing songs, musical rounds, and song fragments "by ear" through all the keys. For individuals or any combination of instruments.

This one book gives you everything you need to learn to self-diagnose your ability to play by ear and then increase your skills by learning to perform familiar melodies by ear “round the circle of keys.”
This same book is appropriate regardless of the wind, string, or keyboard percussion instrument you play. The exercises are arranged in order of difficulty. A fun yet challenging way to become a more versatile musician.
