People have attempted to deduce things from justwhere the holes were drilled in a very very early bone flute....caveman stuff.Gives some indication of the sort of scales they might have used, but not much more really. Spike Milligan had a very good "invention of music" sketch on TV a long time ago. There were a bunch of cavemen sitting morosely round a campfire.Then one of them starts wailing away, not very melodically. The other guys listen for a bit, then ceremoniously stand up, pick the singer up enthrone him on their shoulders and carry him off screen. There is a loud splash. The guys reappear (minus the singer) and sit morosely round the fire.
