Sigh. Started to write my post and fell asleep on the computer. Woke up about 3am.
Anyhoo, here are two pages I found that pretty much sums up what I was going to post.
Again my apologies.
Note that Max(a,b)/(a+b) (for positive a,b) is always closer to the golden section than Min(a,b)/Max(a,b) is.
Some musicologists noted that, in Mozart's sonatas, ratios of exposition and development+recap, etc. were close to the golden secion but that total/development+recap was even closer. The used the above relation to show that this is always true. No musicological explanation needed.
