Can you live without the 5 stroke roll? No, me neither. This little guy gets played a lot. It's one of the 4 numbered rolls on the list because it's an 8th note worth of duple roll (duple=divisible by 2/not triplet). Of course these are quite handy in triplet mode as well as they flow hand to hand. The primary stroke timing comes first and the diddle quality second, make sure your fingers step it up to help with the second beat of each diddle!
