Document Summary
Lecture 3 report: should be familiar w/ course management and materials pages, this week: instructions 4: Read reading 1 sound wave basics. Experiment 1 the candle *due 9/17 at 8pm: books and software should have by now: Audacity downloaded and opened on your computer. Raven (need in a few weeks: get a microphone if don"t already have one. Topics for tonight: software downloads, pitch vs. Timbre revisiting the definitions: physics of music/sound: Terminology and primary wave parameters: wave parameters relationships, audacity demo, experiment 1: candle experiment, experiment process report: quiz format, plagiarism! (consequences, why you shouldn"t do it, assignments, optional: a bit of math . *audacity and raven: audacity = free software, raven = free through csun virtual software lab. Primary wave parameters f frequency: cycles per unit of time cycles per second (hz) T period: duration per cycle (recurrence of repeating elements) fundamentals vs. overtones. L wavelength: distance between repeating elements seconds per cycle (seconds)
