How I Use It
I use it as a rehearsal tool. With some of my advance orchestras, I'll set up chord changes with the tempo of the piece of music we are working on to help with intonation. I'm not a great piano player, so this can help fill in. I'll also use it to record playing tests, so I can continue to work with my class.
It allows music educators with a little, to a lot of music software experience to do almost what ever they'd like musically. For kids it gives all the wonder and excitement of composing right at their fingertips.
