Well, after bringing myself to full alert today with an application of scalding coffe & grounds, I sat down and finished the first movement of the Pentador string quartet. Time to give attention to the third movement now. In this movement, I made liberal use of double stopping. I don't think you have heard anything quite like this before in a string quartet. But not having heard many string quartets, perhaps I am wrong. Well, whatever, here it is.
Pentador Quartet (1st Mvt)
Only about 3 1/2 minutes. GPO instruments, naturally.
