Thank you Bea!
In bars 17 to 25 I mute E in sixth string with left hand finger 1. As I press the bass Si my tip of the finger touches free E.
Thank you Duang!
I play in different parts of strings to get different tone color. I start over the hole, in bars 17 to 25 I play nearer to the bridge, from 33 to 40 near the frets and then again closer to the hole. I would not like to add more coloring to that.
I liked this piece a lot (except the middle part), so I learned it quickly. Also some recordings in youtube like this https://www.youtube.com/watch?v=M1BNrQo ... _g&index=2
helped me understand the structure of the piece. In this version, which I believe is close to the original and close to this periods playing style, there is no coloring.
