So all I wanted to know is what swung 16ths should sound like, thats all.
From my understanding, and correct me if I'm wrong, the harder the swing (in 8th notes), the more "compressed" the 1& will be and the distance from & to the next beat will be greater right?
In a nut shell yes, but in theory the way swing is read is not always the way each player will play it. Swing is recognised as a feel, so many, and myself included, play any groupinging of notes that are to be swung in a certain way. Say for example on a chord sheet, a numbers system, or even just being told a song title but "swing it" I have no real groupings to read, but I know how to swing my part. I may even add or remove notes to make my swing work better for me in its delivery.....or would that be my delivery.
Swing is like a persons accent, it has variations, but the information of what is being said is always there to hear and understand ( I hope )
So people can swing better than others because they way they hear it fits better.
So if your question is one of interpretation, then find your own swing style by listening and developing from the players you admire that do it well. If your question is one do notation, you will find variations of what it "looks like" but in general they are all looking for the same thing....a swing feel.
Within that notation I may be called "rolled or you are asked to play it as "rolled 8ths, as usual there may be no indication of what you roll, but is expected that you know how to do it...and that was the earlier point that some may do it better than others.
It's like putting the actor to the part because his voice fits, Patrick Stewart makes a great Captain Picard, a believable one even, because he was chosen for the part because of his voice, where as say Sly Stallone and his accent would not. The words are the same but one does it better.
I suppose on reflection I have many go to options for when I swing,
A slow swing, a straight swing, a fast swing, a lazy swing, etc, even a swing shuffle of sorts. I make a choice and interprete it my way until corrected, because what I am hearing is not always a MD or composers vision of what is written...especially more so with swing, jazz or blues.
