I don't choose any particular style/composer, though it helps to have a prevailing string section and piano is a plus. Who could I mention? Bach, Vivaldi, Mozart, Beethoven, Rossini, Verdi, Strauss, Tchaikovsky, Rimsky-Korsakoff, these were all from one disc and RCA "Classics Greatest Hits", I have compilations, I found at thrift stores for example "Top Ten of Classical Music - Romantic", I have a favorite I use frequently, from Readers Digest , "The World's Most Beautiful Melodies Great Romantic Piano Favorites", with Rachmaninoff, Mozart, Chopin Tchaikovsky. Look in your local thrift store and you'll find many choices. Also online on Youtube I play classical guitar compilations for my own cats using my laptop.. If you subscribe to Pandora for example you can bring the music with you on your android add an IHome portable wi-fi speaker for any where anytime your selections from your own compilation. Don't hesitate to use vocalizing with music. I just tend to keep it more soft rock or folk style. Many music genre/styles would probably be useful. I have used John Denver, Nancy Griffith, Paul McCartney, Neil Young, Sting.
