The thing is, it's not just an NXT book; it's an integration of mathematics and science with music, and it's done in a way that almost anyone could understand. I'd expect this book to be particularly popular with teachers and home school parents; but anyone interested in music and the NXT would find it a good buy.
The basic striker is so simple that my three-year-old granddaughter can enjoy playing with it. (Notice, I said playing with it. Even my brilliant granddaughter should not be left alone to "build" with an NXT kit.)
The trumpet is so cool, that a "kid" of any age will enjoy using it.
For my money, it's $16 well spent.
