Four-on-the-floor kick on every beat with backbeat snare on 2 and 4 and offbeat hi-hats, the driving foundation of classic disco.
The basic disco groove puts the kick on all four beats, the snare on 2 and 4, and — the detail that defines the style — the hi-hat only on the offbeats, the '&' of every beat. Because the hi-hat never coincides with the kick, the groove lifts on every upbeat, which is what makes it feel like dance music rather than rock.
Each column is one eighth note. x is a hi-hat or cymbal stroke, o is a drum.
1 & 2 & 3 & 4 & Hi-Hat . x . x . x . x Snare . . o . . . o . Kick o . o . o . o .
Count the bar out loud as 1 & 2 & 3 & 4 & and add one limb at a time.
Kick and hi-hat alternate perfectly: foot on the number, hand on the '&'. That strict alternation is easier than it looks and is the fastest way into the groove — get those two limbs going before you add the snare.
Start slow enough to place every note deliberately, lock each rung in before moving up, and only raise the tempo once the pattern is clean. Each step opens the metronome at that tempo.
Ordered by difficulty — the first is the smallest step up.
Four-on-the-floor kick combined with hi-hat on the offbeats. The offbeat hi-hat is the crucial part — it creates the lift between beats that rock grooves, which put hi-hat on the beat, do not have.
Classic disco records sit roughly between 110 and 130 BPM. This pattern is written at 140 BPM for a more driving feel; practise it far slower while learning the offbeat hi-hat.
Four-on-the-floor describes the kick drum only, and appears in rock and house as well. The disco groove is four-on-the-floor plus the offbeat hi-hat pattern.
