A rather neat idea, this, but not executed as well as it might have been. The program draws a guitar fingerboard (the first six frets anyway) and invites you to enter a chord, using letters A to G and the function keys to represent the conventional chord symbols - C7, A flat m6, etc. It then displays the finger positions for your chosen chord on the fretboard and plays it as an arpeggio.

Full use isn't made of the Beeb's three sound channels: the notes ping out in sequence, without a bit of overlap which would give a better impression of a chord being played. Worse still, they actually sound an octave higher than they should on the guitar (perhaps Kevin Rogers, who wrote the program, forgot that guitar music is written an octave higher than it sounds). This elementary blunder is repeated when runing your guitar. It's easy to summon up your E, B, G, etc - but they all come out an octave higher than the true pitch of the guitar's open strings.

Finally, there are a variety of pre-programmed chord progressions available (the booklet claims 98 but it must mean 96). You choose your starting chord (which must be a major), decide how many chords you want in the sequence, from two to five, and your micro does the rest: the chords are displayed on the fingerboard and played (an octave too high, needless to say) through your speaker.

The instruction booklet, by Paul Adby, is clear and accurate; the graphics, such as they are, are rudimentary but quite adequate; only the sound lets it down - which is rather a pity in a program which is all about making sound!
