Pros and Cons of Guitar Tab on the internet

I had to look at an online tab today, why? I had to learn something very quickly (is it any different than turning up to a show and being given a lead sheet?...well yes because a lead sheet will generally be right!), so I google the song and tab....and there it was, and I was able to learn it very quickly....but had I really learnt it? I think (and I am guilty of this), than in the internet age, we simply google 'how to play XYZ' or 'XYZ tab' and look at the piece and learn it, rather than listen to the piece and understand it.So Pros

  • Quick
  • 24/7

Cons

  • Don't actually learn the song
  • Doesn't help improve your ear
  • Might be wrong

What are you thoughts?PeaceNeil
