Dwemeri Tonal Theory – Lesson 93 of Module 1 of 43,788 Modules: Physical Manipulation With Soundwaves
The Razak stood beside his apprentice, eyes darting between the dials and faders of the console, and the sphere being suspended in the centre of the kagrvvar.
“Cut all frequencies on the primary oscillators above ten peaks per second,” he advised his pupil, who did so without hesitation. “We only have need of the sub-bass for this lesson.”
“I am ready for my next task, Razak,” piped up the apprentice confidently, as the sphere froze in place without so much as a quiver.
“Now, incorporating the Low-Frequency Oscillator, I want you to make the sphere oscillate in a parabola, moving anti-clockwise, at a steady tempo of one-hundred-and-twelve peaks per minute.”
His apprentice returned his eyes to the console and back to the sphere, which had dropped fifty-three centimetres, yet was still suspended sixty-seven centimetres from the base kagrvvar. The sphere began to slowly move in narrow circles, moving anti-clockwise. As it rose on its vertical plane thus did its velocity.
The circles grew in radius, the sphere tracing out the lines of a conical spiral. As it reached its maximum height, the Razak expected it to fall into narrower spirals and return to its starting position, ready to repeat the process again. Instead the flustered expression of his apprentice caught his attention.
As the sphere rose for its second cycle, so did its velocity, and exponentially, much to the chagrin of the Razak, the maximum diameter of oscillation without cessation. The sphere was launched from kagrvaar dais and across the hall like a meteorite, narrowly missing the Razak by mere millimetres, crumpling into a jagged lump as it hit the wall behind him. The Razak inspected the crater.
“Troglodyte! You are not ready to learn [Fibonacci] mathematics! Leave and return tomorrow.”
The apprentice sheepishly bowed his head at the Razak’s anger, and hastily vacated the hall, eager to not anger his teacher any more.
“I suppose Lord Kagrenac had to put up with idiocy when he was Razak-Mentor,” muttered the Razak, still inspecting the crater in the wall, thankful it was not his head.
