Learning is accomplished in small lesson steps, each covering one aspect of the music studied. A Macintosh computer was used for this review but the system is also available in PC, Amiga and Nintendo Entertainment System (NES) formats. Miracle kits come in one box, containing a keyboard, leads, power supply, software disks and manuals. This is an appealing prospect for anyone with musical interests and there would seem to be a vast potential market for an effective teach-yourself scheme. After six to 12 months, the 'average beginner' should be able to play with two hands, read music, perform in a music group and be capable of making further progress alone.

And some of us, of course, would prefer to make our stupid mistakes in the privacy of our own homes! Lessons are a big help, but not everyone has the time, money or inclination to seek out a decent piano teacher and engage in what could be a long course of tuition.
