Trying to learn a song, when I play the tabs it doesn't sound right. So I look at the top of the page it says "Tuning: All Half Step Down" So do I turn the pegs half a full rotation lower or what?
no, you tune them one half step down thich means that if you have a tuner you shuld tune 'em all to Eb, Ab, Db, Gb, Bb, Eb.
^^ no need to laugh mate,
but yeah its refering to the actual notes of the open string,
if you dont have a chromatic tuner or a keyboard to help you it can be pretty difficult though
