Generate drum loops with Drumloop AIWhat 90 BPM is for
Ninety beats per minute is the centre of gravity for boom bap and a huge amount of hip hop generally. The reason is partly physical: 90 BPM is close to a relaxed walking pace, and the swing that producers apply to the sixteenth notes at this tempo produces the slightly-behind, head-nodding feel the style is built on. Push the same pattern to 110 and it stops swinging and starts hurrying.
The tempo is also convenient mathematically. At 90 BPM a beat is 667 milliseconds and a bar of 4/4 is 2.67 seconds, so a four-bar loop is a shade under eleven seconds — the length most sample libraries default to. Producers chopping breaks find that a great many classic funk records sit within a few BPM of 90, which is why so little time-stretching is needed when building from vinyl.
For practice, 90 BPM is the tempo at which most players are at their most accurate, so it makes a poor test of your timing but an excellent place to build technique. Work on feel here rather than endurance: play deliberately a hair behind the click, then deliberately ahead of it, then dead on. Being able to choose your placement rather than merely landing somewhere is what separates a groove from a grid. The 90 BPM loop library is a good reference for how the pocket should sound.

Frequently asked questions
Why is 90 BPM so common in hip hop?
It matches a relaxed walking pace, and swung sixteenth notes at this tempo produce the laid-back pocket the genre is built around. It is also close to the natural tempo of the funk and soul records that were sampled to create the style, so loops taken from those sources need little or no time-stretching.
Is 90 BPM good for beginners?
Yes — it is arguably the ideal starting tempo. It sits in the range where human timing is most accurate, so you can concentrate on technique rather than on chasing the click. Once a pattern is comfortable at 90, use the speed trainer above to add one or two BPM every couple of bars.
