Just an interesting bit of info trivia about the Pentatonic scale. Although it is the most common scale of 5 notes used throughout the world and “sounds” Chinese played “randomly” it is also the basis of the notes used exclusively in the following well-known Western tunes and riff: (and therefore possibly to be avoided)

Robbie Burns’s - Auld Lang Syne
Rod Stewarts - Sailing
Willis’ – Sweet Low Sweet Chariot
McCartneys’ – Mull of Kintyre
Led Zepplins’ Riff – Whole Lotta Love

Thanks to Howard Goodall’s program series “ How Music Works” for pointing this out. Worth watching all the series parts for PGMusic users:
