Vals by Bartolomé Calatayud (1882-1973). The thumb plays a bass line, just one note per bar, index and middle fingers play the accompaniment, and ring finger the melody. Apart from a run of bass notes mid way, it follows the same pattern throughout, uses the open strings and makes infrequent use of the higher frets. I was almost able to play it by sight-reading and yet, by bringing out the melody line and applying some vibrato, it can sound quite nice. It’s probably one I should have tackled earlier, but it’s good to have some sight-reading practice.
