In pedagogical circles he is probably best remembered for his Schulwerk (1930-35), translated into English as his "Music for Children." http://www.wikipedia.org/wiki/Carl_Orff

The Orff system starts the young musician on the pentatonic scale to encourage improvisation. Once that's mastered, most Orff instruments have spaces to add keys to then make a diatonic scale. http://www.tidewater.net/~xylojim/tunings.html
