Playing in Odd Meters can be difficult but also a lot of fun. In this Guest Odd-Meter Lesson Gregory Bolomey from Axe of Creation demonstrates an E funk groove in 7/4. Playing grooves like this is essential to learning to feel odd-meters and certainly worth the practice time.
For me personally I also found that working on odd time-signatures has opened up my playing in 4/4 and 3/4 a lot.
