The first two times I played through, I just forged ahead as well as I could. I didn't get the voicing right and I stumbled through the trickier rhythms. Tempo was probably half speed.
Later in the evening I analyzed the piece some more so I could play more accurately. There were two patterns that I struggled to understand: measure 13 and others like it, and measure 37 and others like it. In both cases there is an eighth rest that I mistook for a 16th rest so there didn't seem to be enough 16th notes in the measures. Once I realized those were eighth rests it made sense.
I worked for a while on those two patterns and then played through a couple more times paying more attention to voicing. It was a lot harder than my first read throughs. If I decide to learn this piece it's going to take a lot of time and effort (it always does! ). This is a lovely piece and it would be worth it!
