I suspect based simply on number of musicians, it's opposite. Many popular-music performers and songwriters have classical training, and take on classical themes. Classical music is single-digit shares of total music industry revenues, around 1--3%.[1] That said, music is a form of communication, and there is and always has been a tremendous amount of cross-fertilisation and inspiration from other forms, whether you're talking traditional melodies adopted in classical composition (Dvorak's Slavonic dances, for example), Gershwin adopting jazz (Rhapsody in Blue) or western music (Copeland in Rodeo), or popular music taking up themes from classical works (Sting's "I hope the Russians Love Their Children Too" quoting Prokovief's Lieutenant Kije, the Beatles quoting Beathoven's "Ode to Joy" in "All You Need is Love", and Led Zepplin's quoting from Mussorgsky's "Pictures at an Exhibition" in "Kashmir"). As well as, of course, wholesale popular adaptations of classical music and vice versa, and performing and composing in different genres. ____________________________ Notes: 1. <https://medium.com/@AmericanPublicU/popular-classical-music-how-popular-is-classical-music-part-ii-4040456752db https://medium.com/@AmericanPublicU/popular-classical-music-...>
