String Quartet movement

My string quartet writing tends to be pretty focussed on the quartet aspect, rather than on the individuality of the musicians, so I wanted to try and write a quartet that highlighted this more. This is in the spirit of a slow movement within that quartet, although I might be trying to reframe the movement structure and haven't quite figured that out yet. If you know of any works that might be what I'm going for, please throw them my way~ ty ty
