I used to do musical direction and arranging for a well-known children’s musical theater group in my area.
The creative genius behind this group had an uncanny gift for turning out quality song melodies, chord sequences and lyrics, which he would sing for me while playing the piano. I would record his renditions and then use the cassette tapes to do studio recorded orchestral-type arrangements to back up the performers on stage.
One year, when Disney came out with the movie Pocahontas, this guy was irritated by how much the movie changed the actual story. So he decided to write his own musical version of the story, which has since been performed locally for years in local theatrical venues.
In creating his play, he decided he wanted to avoid all the typical movie cliches about what native American Indian music actually sounded like. So he spent time trying to research the actual music used by tribes of that period in order to write songs that would at least accurately reflect the sound of tribal Indian music.
Guess what? After all his research, he finally had to accept the reality that there was no real Indian music other than the basic pounding drums and the the droning vocal chants so often portrayed in Hollywood movies.
The American Indians had no real music that matched the discussions in this very interesting article. So not all cultures have music.
Compare with this guy, a Mongolian throat-singer, who actually manages to sing a duet with himself. He's simultaneously emitting two distinct vocal sounds: along with a continuous drone, the singer produces a melody of harmonics. Khoomei Mongolian singer. Start at 7.11
It's all about physical capacities and constraints. In voice that includes lung capacity, larynx flexibility, etc. as well as --- on instruments --- trained muscular limits.
Some people are really vehemently against synth music, drum machines and so forth, because they exceed the capacity of what is physically possible for a human being. Synthesizer music, they would say, is inhuman music.
