Attendance and Homework are 45% of your grade!
Homework will be corrected and returned, but not graded.
Due dates for homework and take-home quizzes are final - no late work accepted. Work is due at the beginning of class.
If you cannot return an assignment to me at classtimes, you may leave it BEFORE THE BEGINNING OF CLASS in my box in the HFA office (A19) - you must call or email me to let me know it is there, or you will not receive credit for having turned it in on time / at all.
Occasionally, depending on circumstances, I may allow you to email your work to me before the end of the class period in which it is due.
MUSM 306 is an alternative course for MUSM 342, the 1st Recording Studio Techniques class.
Either MUSM 306 or MUSM 342 may be used as the prerequisite for MUSM 344, the 2nd Recording Studio Techniques class.
MUSM 306 may also be taken for elective credit by those who have already taken MUSM 342.

Some of these are Word and Excel docs I created, others are links to online Acrobat pdf's, gifs, jpegs, or html, etc websites. If you have any difficulties with the Excel or Word docs, please let me know. (IE opens them OK on my Win system, which doesn't have Excel on it)
Please let me know if any links don't work or have died. I run a linkchecker regularly, but some websites seem to get 'redecorated' constantly...

Formulas :
Frequency = 1 / the period of one cycle (Ex: 1 / 10 milliseconds = 100Hz)
FYI: Period of one cycle = 1 / Frequency (Ex: 1 / 100Hz = 0.010 seconds = 10 millisec's)
Wavelength (lambda, Λ) = Velocity / Frequency
Wavelength = The distance it takes for a wave to complete one cycle, in feet or meters.
Velocity = Speed of Sound (~1130 feet per second, ~1ft/msec, ~344 meters per second)
Frequency = Cycles per second (Hz)
