It has written "Solid 4 beat". Now, I assume that this means NOT swing. But frankly, I find it sounds ten times better with a bit of swing, and when I tried playing it in strict 4/4 time, it was very difficult indeed!
Which takes me to another, rather strange problem. Does anyone else find that when they've been playing something with a swing beat, it's quite difficult to revert to normal time? A few years ago I even found myself playing some Mozart like this. Of course, he may be turning in his grave, but secretly, I bet he's jealous.
