This is probably a joke but I'll answer anyway
By 'cheeks' they mean buttocks so by "making them clap" is referring to them being so big/thick that they clap or make noise when you walk or move around or something.
I probably got played lol but whatever
Contrast: The work in today's art is a lot more advanced. Prehistoric people were simple and didn't use the major fundamentals of art. They're work is really abstract and really only consisted of warm colors and black.
Compare: Like some of today's artists, some of the prehistoric painting tell stories, or describe ones feelings.
Hope that helps!!! <span />
The answer is basso continuo
From the Italian language sometimes abbreviated as b.c is a technique of self-composition and execution and essential from the Baroque period
The basso continuo is played for one or various instruments, typically and harmonic as the keyboard instruments or others as the harp or lute
with the voice of bass simultaneously in charge of an instrument of grave tessitura like the violoncello, bassoon, the viola da gamba, contrabass and sometimes contrabasso.
It also receives the name of simultaneous accompaniment
The two paths that modern classical music divided into were careful control and more freedom
