It's pretty vast, sweets! I played classical violin for 11 years and my father wouldn't let us listen to pop until we were 13. LOL! He actually had a full-scholarship to Julliard, which he turned down. He didn't want to be a starving musician. So--It depends what you're in the mood for.
For the most part, anything by Mozart has mass appeal.
Bach is light and romantic.
The most romantic of them all: Paginini
For a full symphony, the Russians: Tchaikovsky, Rachmaninov, Prokofiev, Stravinsky, are all "sweeping" in their sound. For a more modern take on that, the Finnish composer, Sabelius, is easy to listen to.
The Germans are dramatic, like a winter storm....Beethoven, Brahms, Wagner, Schubert is the most romantic of them.
For soft piano that's almost wistful and aching, so beautiful: Schumann.
For happier piano, like "ballet or lunch music": Chopin
Modern, bold mix of symphonic and sonata: Dvorzak and Liszt
Any cello music moves me.
That's just a start....hope it helps. PM me if you want to know anything!
