Hi John - Sorry, I didn't make myself very clear! I work as a guitar tutor for schools teaching kids aged mainly between 8 and 16, and was approaching the question from that angle. Obviously, guitar is not the only tab instrument, but the process of tabbing (as I know it) is limited to instruments that have strings and frets. I find that students who only learn tab find it well-nigh impossible to communicate musical ideas to players of other instruments and was therefore suggesting standard notation as the most convenient common musical language. However, if one of my kids asks to learn a famous rock guitar solo I'll tab it rather than dot it, as its far less confusing!

As far as blues harp goes, I wasn't aware that tab actually existed for it! How does it work?

Sorry if I sounded a bit pontificaty (is that a word?) in my last post, but put it down to being fed up with students bringing tabs that they've pulled from the internet that are generally a) incomprehensible and b) wrong!

Chris :)
