Sketchbook Week Four

Making sounds in PureData
Create two scales of our own

Scale 1 The Cat's Meow
The idea is that if we use a scale that sounds good to our ears because that is the scale that we can hear well, I cat's scale would be different and would also be reflected in the sounds it prefers to make.
I taped a cat and then did an FFT on it's sounds. Some math and came up with 5 notes with the following ratios:
The particular cat I taped had it's lowest tone at 352.71 Hz

Scale 2 The Golden Scale
I began by looking at the fibonacci series. I quickly then quickly found that I couldn't just plug the numbers in, they either grew too quickly or had no logical end point (where to start a new key).
However the fibonacci series suggests a ratio of it's own. If you divide one number by the previous they quickly tend to a number, 1.618034. It turns out that this number is the golden number
So starting at 220 Hz I made a series by multiplying:

So then I corrected the golden number, changed it to 1.148732 and got this scale:

However, I like the incorrect one better...
