First, I am not sure whether it would be ok to ask a question like this in this category. If it is inappropriate, I'll erase it.
I bumped into Aaron Copland's saying, "... all American music could not possibly be confined to two dominant jazz models: the 'blues' and the snappy number."
I didn't know what "snappy number" was, so googled it in many contexts but still can't figure it out.
It seems like a genre of Jazz, as the word "snappy" suggests, but is also combined with the "number", which makes me more blurry.
Can anyone help me figure out what that is?
Thank you.
