Nic shrugged.
Although it was against his principles to pick fights with people of higher authority, he didn't really have a choice.
-As long as you don't kill me, I'm fine...
There were some loopholes in his statement; thus Nic took full note and decided to make use of them.
Preparing the jutsu, he made a few extra seals at the start- since the instructor would probably have never seen that jutsu before, he would treat it as one full jutsu, not two jutsus performed together. And in fact...
As the first jutsu was done, with just a few simple seals, the sound became louder.
The requiem- he wouldn't have risked it without another layer of cacophony, but the class was already noisy enough.
It was only about a second or so anyway. The second jutsu was completed as easily, and consisted only of controlling wind direction through leaking chakra into the air. Like a conductor, one could control the rise and fall of the wind.
The wind increased in speed- and as a result, the sound grew louder. Although it masked the melody, it would still affect on a subconscious basis- and being ignored was the whole point of that jutsu.
Flicking a few needles into the air, he allowed them to ride the currents of wind, penetrating through the wall behind the instructor. Ahh... of course, his aim wouldn't be so bad normally, but who was to know? A few more needles... and he kept missing, pretending to curse and keep trying again. The whole idea was to prolong the period.
In the flow of wind, he could sense the instructor using a shield (of wind too, it came as a slight shock) to ward off projectiles. Not that it mattered, of course.
Pausing, he did another hand seal, to allow the flow of wind to be sensed with greater precision, in case the instructor decided to end it- allowing him to evade. Once completed, he continued his barrage of needles with slightly greater accuracy, allowing one in a few to strike the target- giving the impression that the jutsu was to allow better accuracy. As expected, it glanced off, but he persisted, his accuracy apparently becoming worse in his "rage".
OOC: Refer to my sign up post thingy for the effect of that first jutsu ^^
