Rock in odd meters isn't fusion in odd meters. The phrasing has to remain recognisable — there's still a backbeat, still a riff, still a chorus. The drummer's job is to let an asymmetric meter feel like a groove rather than a math exercise. Pink Floyd's "Money" is in 7/4 but it never sounds like an experiment; Tool's "Schism" cycles through multiple odd meters and still feels like a song.
The technique is the same as it is in fusion odd meters: feel the meter as groupings, not as a count. 5/4 = 3+2. 7/8 = 2+2+3. 9/8 = 2+2+2+3. 13/8 = 4+4+3+2 or 3+3+3+2+2 depending on the band. Once the grouping is internalized, the meter stops being odd and starts being shaped.
Metric Modulation
The fourth exercise introduces metric modulation — a tempo-mathematical shift where a subdivision in one meter becomes the new beat in another. The 8ths of a 4/4 bar at ♩=100 become the quarter notes of a new section at ♩=200. Done well, it sounds like the band has changed gears smoothly. Done badly, it sounds like a car crash. We'll do a simple version: 4/4 to 5/4 with the quarter note staying constant.
