The tone of this sound composition is pretty explorative and "curious." I think the beginning sets that up with a question that is later built upon by layering on more sounds that sometimes go in different directions.
Forms wise, I think that this resembles an assymetrical binary, since although there is a specific beat playing throughout the piece, the other stream playing alongside it is much different in the first half then it is in the second half. At 18 seconds in there is a short pause that strengthens the departure from the first half to the second half, and the beginning of the second half is less stable and predictable.
