Nobody claimed one culture’s music was beautiful to another culture. A lot of palefaces don’t like roast opossum either. I’m sure that for something to be presentable to a paleface audience as inspiring music it would have to be done in a paleface musical idiom.
I am not a music ignoramus by the way — I am a pianist of over 42 years experience. Some Western musicians have done impressions of American Indian music as well and it isn’t that bad, but of course it has the Western harmonic spice in it.
I’m not a musical ignoramus either — former professional guitar player and arranger, magna cum laude graduate of Berklee College of Music decades ago. I am very open to music of foreign cultures. Developed a love of East Indian music — which has no vertical harmony at all — in high school. I like Japanese koto music, middle eastern music, African drumming and singing. But you couldn’t pay me to sit through a concert of traditional American Indian music.
