Good Lord....surely it would be easier to just learn to read music in standard notation ? Why do people insist on making things harder for themselves ?

This really does seem like the LEAST useful convention I have EVER seen for musical notation. The ONLY possible advantage it can have is that it is text-based, thus allowing people to post the tabs on websites easily, which only serves to violate copyright laws anyway.

I wouldn't bother learning piano tabs -- it's not likely you'll see them very often.
