Engineering Math, Period 2, 18 Sep '09

This morning the students would be greeted by the sound of slowly played scales, as Mohinder picked out notes in a repeating rhythm that accelerated into an abrupt stop. "Humans have a audiable range of anywhere between twenty and twenty thousand Hertz. Usually," he added. "Now frequency is inverse to wavelength," Mohinder said, moving to the board behind him to start sketching out formulae.

"Sound is a compression wave through matter, and - if it's sinosoidal - we can define it by amplitude, spatial frequency and phase." Mohinder continued for a while describing velocity, modulation and standing waves.

"The musical instruments in front of you agitate and produce a range of pitch and frequencies while producing some very different sounds, and mathematics can be used to describe not just the sound they make but also the composition," said Mohinder, passing out handouts. "Try out some of your own compositions and rhythms."

The Danger Shop has created modded instruments for you to try out, just not all of it is tuned correctly. Sadly, no earplugs.

Chords, majors, minors, scales (http://en.wikipedia.org/wiki/Music_and_mathematics#The_Golden_Ratio_and_Fibonacci_Numbers), 2/4, 3/4, 4/4 time. (http://en.wikipedia.org/wiki/Time_signature)
