A question regarding clical music?

I like to listen to clical music while i read so i put on an internet radio station playing music related to Mozart, Bach, Beethoven, etc., but I often find that the music can get really dramatic and sometimes distracting, what would you suggest if i want a light mellow sound preferably nothing with vocals, which was my mistake looking up Georges Bizet, and preferably no wind Instruments, i like stringed Instruments and the occasional piano sonata
