Can the G or D strings be muted by Cellist so that a double stop can be played on the G and A, or C and D strings? Would greatly appreciate a response.
There is no way to 100% mute a string in a way that would allow it to be used again quickly and without the cellist stopping. In general all double stops need to be able to be played on adjacent strings, 3 string stops exist but are played as a flam from top to bottom as it's not easy to reach across 3 strings at once with the bow. The bridge is curved so to play 3 strings at once the middle string would have to have a ton of pressure on it.
