So I woke up this morning and I listened to Shostakovich Quartets over and over until midday, when I decided to try to make a quartet. I ended up making two, each with 5 movements, but I thought they were too heavy and fuzzy, so I deleted them but kept this one. If I remember correctly, it was the second movement of the first quartet.
There's really nothing special about it, it's pretty much just me messing around with string instruments for three minutes.
