For years I've screamed at sheet music and teachers on the tube when I've wanted to learn a song and found it was in open 'G', drop 'D' or some other exotica. Generally I've managed to find a way round it either by myself or with internet rummaging. I've always had one thing in the back of my mind, somebody told me years ago that Tony Iommi used to change his tuning to suit Ozzies lack of vocal range. I've never had much sympathy for vocalists so I always thought alternate tuning was an unnecessary evil and that vocalists need to sort themselves out and not expect everyone else to bend. How wrong I was - now I get it! This might seem a bit stupid but three days ago I managed to get my Tremonti successfully tuned to open 'G' for the first time. I've tried it in the past and never really got there for one reason or another. All of a sudden the tunes I thought I knew in standard tuning that were originally alternately tuned come to life in open 'G', they actually sound right and I'm playing slide like a pro!! Unfortunately I've got to re-learn a few tunes but at least they will sound right! Wanders off to look at 7 stringers, not quite GAS yet . . .
