Re: Oh well
I wouldn't recommend this. First, this is more expensive than a larger keyboard with relatively few features. The cheap ones with 49 keys (four full octaves) will undercut this price quite a bit. The main reason, however, is that every keyboard I've seen with fewer than 49 keys has also taken the liberty of shrinking the keys so they're no longer the size of piano keys. That is bad because smaller keys will wreck the muscle memory that can be key to advanced fingering techniques. Using keys that will be of the standard size as any other piano, keyboard, organ, or harpsichord means that it will be easier to play more complex pieces later on. If you'd like to introduce people to piano playing, check for the basic midi keyboards for as cheap as is available; they'll probably well outstrip this.
