It's hardly groundbreaking to say that music is valuable for children's education. Plato is widely quoted as saying “music is a more potent instrument than any other for education.” Justin Bieber thinks its important, too. I, for one, wouldn't want to argue with either Plato or Justin Bieber.
We also own two toy guitars, one from Little Tykes and another from Paper Jams. The Little Tykes guitar has nine switches of various types: five push buttons, three strings to pluck, and one slider. It plays a few notes and some low-fi renditions of old rock songs.
Paper Jamz has no switches. Instead it senses your fingers over the strings and plays music. We also have a drum kit from them as well. They let you play music on your own or play along with one of the built-in songs. Different models include different songs; we bought Jackson the guitar that plays “Machinehead” by Bush.
I'm a big believer in adapting things to work with the iPad. Jackson did a pretty good job of accessing the instruments without any adaptation, though. There also isn't much point in switch-adapting them when you can buy GarageBand for $4.99.
GarageBand give you keyboards, guitars, basses, drums, violins, and lots and lots of related instruments. It's a powerful tool, and apparently people with much more talent than I possess can compose complete songs with it. Jackson is particularly fond of the Sampler, where you record your own sounds and then play them back on the keyboard.
The app can be a bit tricky for someone without much motor control. Many of the targets are quite small, and accidental swipes can pull up menus to do things like change the Scale to something called “Mixolydian.” I generally sit with Jackson while he's playing to help him escape from such situations. But it's one of the best $4.99 purchases I've ever made. With the Autoplay feature, in a few taps Jackson can create music that sounds like he's been been taking lessons for years.
