Question

Karlheinz Stockhausen used a technique where musical instruments are ring modulated with these sounds in works like Mixtur and Mantra. Hewlett-Packard’s first product, the 200A, used a Wien bridge oscillator to generate these sounds with low distortion. The iconic Roland TR-808 (“eight oh eight”) kick drum (-5[1])is essentially made by filtering and processing a low one of these sounds. (-5[1])The only album Aphex Twin released under his Polygon Window alias is titled for “surfing on” these sounds. (15[1])These sounds are usually not used for subtractive synthesis since filtering them only changes their (*) volume, while additive (-5[1])synthesis works by adding these sounds together. (-5[1])This sound joins triangle, sawtooth, and square (-5[1])or pulse as the (10[1])four main waveforms (10[1])used by synthesizers. For 10 points, name (10[1])this sound that has no harmonics or overtones, (10[1])meaning that its waveform is a single trigonometric function. ■END■ (10[4])

ANSWER: sine waves [accept pure tones or sine tones; prompt on just “waves” or “tones”]
