To learn shuffle, you need to listen to this video by Mike Clark. You also need to listen to every groove Bernard Purdie ever played in his entire life. Then you need to listen to other modern interpreters such as Jeff Porcaro's classic Rosanna shuffle. Then... maybe, Grasshopper, you will finally understand.
Also,if you attempt to do any type of fills with shuffle grooves,they have to fit into the shuffle,lol.Usually these would be fills based on a triplet feel,broken up,or otherwise.
I had a guitar player say: "Dog track." and I played to what the guitar player was laying down, which was the flat tire shuffle. It worked, so that's how I know it as a Dog Track.
