Got completely distracted from my regimen today. I heard three different renditions of Augustin Barrios's (aka Mangore) Una Limosna por el Amor de Dios and tried to play the first three measures. I had only mild success but that caused me to try harder. Needless to say, my study time was spent exploring tremolo.
I want to play this piece someday. I'll need to incorporate Vladimir Bobri's exercises into my daily routine.
