Before I moved to ukulele from guitar due to sore fingers, old age. Most guitar players I knew tuned down one half step and many tuned down two half steps - one whole step. The reasoning was easier on voice and easier on fingers. Plus slapping on a capo one could be back in standard in short order. Every string instrument I own is tuned down two half steps except for my baritone ukulele. One guitar is in DADGAD, a great tuning. I love fingerpicking and look forward to the day that I can finerpick the melody and sound good. Since going to ukulele I have sort of fallen in love with Chord Melody on the ukulele.
