Somewhere, no, not over the rainbow, I've read that most very early instruments, things like bone whistles seem to use the pentatonic scale, no matter what culture, continent or clan developed it. Similarly, baby's comfort songs, such as "The Galloping Major" mimic the rhythms of walking as felt in the first comfort zone, the womb. Might be interesting to see if similar scales seem to play a part in calls used by our closest relatives or other animals.
In the same kind of vein, I recommend the John Kirby Sextet (1939 -41) who alongside standards of the day also recorded their take on many classical themes. All beautifully tight, cool, laid back and swinging. Bounce of the Sugar Plum Fairy, Beethoven Riffs On, Anitra's Dance, Minute Waltz and Humouresque included. This kind of arrangement was the precursor for the tight arrangements, often with Kirby's bass carrying the rhythmic momentum, that when merged with modern harmonic progressions emerged as bebop.
Also for a tour de force on Humouresque listen to Art Tatum's version, with it's astonishing runs, apparent playing out of time (like Earl Hines used to do) and incorporation of Harlem stride.
