13. In Assignment #2 (Battle of the Bows) you mention "no percussions, woodwinds, brass or choir allowed" and at the same time "any other acoustic instrument is allowed". I'm not sure how to interpret this. Can you clarify?
The answer to this dilemma, without getting into too much detail to confuse you, lies in the answer to the following question: do the instruments you have in mind also qualify as strings? If the answer is "no" then you're not allowed to use them at all. This includes marimba, glockenspiel, bells etc. If the answer is "yes" (e.g. piano, harp, guitar, etc.) then you can use them. But with one rule in mind: do not generate percussive effects or use them with your hands like percussions (e.g. take the cellos or guitars and hit them to create percussive sounds). This isn't allowed and it will disqualify you.
