@damoshe: to explain a bit more about the nigun:
questions are a lack of understanding.
its explained in kabala and chassidus that questions come from klipa that covers over on kidusha. so when a person rises to a higher level, he understands the sugay better and the questions disapper. this can either be by learning deeper or be revealing a deeper level in the neshama.
in Raaya Mehemna, it says that “a kashya – query…emanates from the side of evil.” this is explained in tanya igeres 26 and more at length in hemshech 5666 page 120-122 in the new print
to point out for those who want to see for themselves, look at any maamer of any of the chabad rabbaim. almost all them start with questions on the parsha or holiday, then explain an idea in chassidus, then answer the questions automaticlly. this is more clear in a continuation of maamarim like 5666 (60 maamarim) which is one lenthy idea in chassidus slip up into 60 shabbosim and y”t. and each week the rebbe rashab added questions on the parsha, then continued the idea where he left off, then answered the questions. Because thru a maamer which reveals yechida shebinefesh and yechida of torah – all the questions are answered.
