After further study, I found more. The Fibonacci Sequence DOES apply to the Ukulele. Look at the picture.

My Ukulele is 21 inches long, a Fibonacci number. Look what happened when I did the Fibonacci sequence on a picture of my Ukulele on Paint. (Sketch is a little rough.)
The end of the fret board, the hole, the string, its all the golden ratio!
So, it DOES apply to music!
