Hey guys! Chk the Guitar software "Guitar Pro 4". This software is amazing when it comesto decoding tabs or chords. There a digital guitar tuner with this software too so u dont need to buy a tuning device. For beginners, its awesome in way that it helps them differentiate between the notes and how the tab should sound like. Whenever the new tabs or chords r published in the site. People can listen to the tab and this way they would practice and can chk with the software if one is playing the tabs or chords accordingly. Professionals can compare each other tabs without even touching their own guitar and digitally fix the tab/chord rachothers and upload it to the server. Well! This would be a new evolution in sharing tabs/chords.
