Watch the Prague 7/8 online guitar lesson by Jeff Scheetz from 50 Blues Rock Rhythms You MUST Know

So a riff in 7-8 is a little tricky to get at first, but once you start to play a few different 7-8 grooves it will start to feel a little more natural for you. Just remember to count at first, and as you count 1 through 7, don't forget - don't say 'sev - en' because that will take two beats - just say 'se' and you should end up back on the downbeat!
