While it is true that Frank had a great sense of humor, he was also very serious about composing music. In reality there are only a handful of skilled players who can play his most complex pieces. It takes a lot of patience to learn and requires a fantastic memory.

Dweezil ZappaI didn't really hear any other music other than what my dad was working on until I was 12. My recollection of hearing other music was that I liked some things that I heard but I always thought, 'Where's the rest of it?' It didn't have the same amount of detail or instrumentation or imagination in the arrangements.
