# Use [[http://audacity.sourceforge.net | Audacity]] to generate two scales via sine waves: a just scale (based on harmonic overtones, i.e., naturally occurring oscillations), and a equal-temperament scale (based on balanced keyboard tuning, i.e., technology driven).

Added lines 35-36:
# Pick a scale and create a melody. The melody should be constructed with sine waves like the scales above.
Changed lines 37-38 from:
Create a more interesting melody (use harmony, i.e., two or more voices). (''Hint:'' If you select a song like "Row, row, row your boat", it is easy to add harmony, since you can reuse the same voice - just copy it and shift it in time.)
to:
The more you do, the more bonus points you earn...

# Create more scales. For instance try:
** [[http://en.wikipedia.org/wiki/Pythagorean_tuning | Pythagorean Tuning]]. Question: What happens if instead of 3/2 you use the golden ratio (1.61803399 ...)?
** [[http://en.wikipedia.org/wiki/Just_intonation | diatonic, Indian scales
and others]]
** [[http://en
.wikipedia.org/wiki/Meantone_temperament | Meantone Temperament and others]]
** anything else you find

# Other ideas...
Added line 60:
## Describe the two scales. Create a [[http://www.phy.mtu.edu/~suits/scales.html | table with frequency ratios]] for each scale. Repeat for bonus work.
Changed line 68 from:
# '''Three''' final mixed-down audio file (see Audacity's ''Export'' menu). The format should be MP3 or OGG.
