Need Clarification, LOA 4, Improvising Homework

Hi David,

In the final homework assignment, in LOA 4, Improvising, should the end product be entirely original or should we/can we, borrow licks from material already presented?  In presenting the assignment, you mention both, using original licks and borrowing from already learned material.  (The challenge is to come up with an instrumental using all five chorus forms.)  Making it all original would obviously be more challenging.

Thanks in advance.

Homer.
