For melody (lead), I’ve come across the following principle: “Steps are easy, leaps are hard.”
The underlying assumption is that leaps are more difficult to sing along with and therefore considered less melodic. Does the opposite apply for bass or would it depend on the lead?
In the same train of thought, would a busy drum rhythm imply a more simple bass line and vice versa? Which drum part(s) would you associate most with the bass line?
When do you record your bass lines live (with or without quantisation) and when do you rather resort to a sequencer?
