I've been working from the book Graded Repertoire for Classical Ukulele with arrangements by Jeff Peterson. I'm plugging away at learning to translate written music to ukulele strings and learning some basic techniques from classical guitar as applied to the ukulele.
I could practice the same pieces forever, probably. So I thought I'd finish them as you do when you take piano lessons: perform them. In my case, I thought I'd record the pieces I really liked, and then declare myself done with those pieces. This is my first effort, "Estudio No. 1" by Dionisio Aguado (1784-1849), arranged for uke, as noted, by Jeff Peterson. This is the 4th piece in Grade 1 (of 8), and has been my favorite so far.
