After a year of delays

At a glance, Rocksmith looks likeGuitar Hero, with the screen showing a guitar neck stretching towards the horizon while coloured notes zoom towards the bottom of the screen. The difference is that you use a real guitar to play - acoustic, electric or bass - and the software detects whether you played the correct note or chord. You can therefore use it to learn how to play a real guitar with a library of real songs and tutorials to help you along.

As I slouch further towards middle age, I’ve discovered that it’s fun to buy dumb things as weekend projects, and that as far as “dumb things” go, musical instruments are relatively inexpensive. In the past year I have bought a keyboard, a harmonica, a ukelele and a melodica. I can’t play any of these instruments, but who can say no to a £15 melodica, an instrument which crosses the elegance of a piano with the anxious honking of an accordian? A more restrained dad than I, obviously.
