JoyTunes is a site I just found out about from the excellent site, Edshelf. This is a wonderful free site for Music teachers to teach students learn how to play an instrument. This is done by playing real instruments in combination w/ online games. As of right now there are only games for two instruments, the piano and the recorder. A great feature is the educational portal which allows teachers to send invites to their students and track student performance.
I highly recommend checking out JoyTunes by clicking here!!!
