BUT if only I had this sort of fun-techno tool to learn my music theory back in my youth!
I love my iPod/s and so I was particularly interested to read about iTheory, from Duke University.
iTheory is a beginning music theory ear-training program for the iPod which allows on-the-go users to practice interval recognition, scale recognition, chord recognition, and perfect pitch. This program is a complex network of over 600 interactive text notes with links to over 200 audio clips. All iPods with the Notes feature – 3rd, 4th, and 5th generation iPods, as well as the iPod mini and iPod nano – are able to use iTheory.
