i will ask my local friend, Joel-Francois Durand, professor of music composition and acting director the School of Music at the University of Washington, classical (20th Century period😁) composer, and builder of my tonearms, whether he disagrees with the Oxford dictionary definition of Classical music.

he is an expert. and an audiophile.

btw; he also really enjoys the Nojima Plays Liszt recording on Lp and tape.
i have learned much from him.
i know he will tell me to just enjoy the music. and don’t worry too much about it. maybe....if i was in his classroom, he might tell me differently.
