Study No. 1 (Regret)

This is a study I wrote to help smooth out a section in Media Luna (long page, ctrl-f the title).

The first string is the melody, and its first use each measure should be loud and with vibrato. The second (and sometimes third) use of that string in each measure should be softer, sweeter, and (most importantly) regretful. It's also full of big stretches for the left hand.
