Of the three basic and equal parts in music,
(melody, harmony, rhythm), rhythm is the
most abstract.
It's understandable that many music lovers
don't like music that is only drumming, or
drumming and poetry. Rhythm is the least
understood among the three parts of music.
The old song, Fever, as sung by Rosemary Clooney (?),
uses snare drum with brushes, a stand-up acoustic
bass, and vocal melodies. No other instruments,
if I remember correctly. It was a risky decision
to record it that way, but it was a big hit at that
time (early-middle 1950s?).
Rap music is drumming and recited poetry. No
melodies, no harmonies. Like beatnik coffee houses.
