12/8 has twelve eighth notes in every bar, grouped in four sets of three. It feels like four big beats, each one split into a triplet, and it is the sound of slow blues, soul ballads and doo-wop.
What does 12/8 mean?
The top 12 means twelve notes per bar, and the bottom 8 means they are eighth notes. Like 6/8, it is a compound time signature: you feel four main beats, and each one is three eighth notes long.
You can think of 12/8 as 4/4 with every beat played as a triplet. That is why a shuffle groove can be written either as 4/4 with a swing feel or as 12/8.

How to count 12/8
Say it: "ONE and a, TWO and a, THREE and a, FOUR and a"
Most players do not count to twelve. They count the four big beats and say the triplets in between: "1 and a, 2 and a, 3 and a, 4 and a". The big beats land on clicks 1, 4, 7 and 10.

The tempo in 12/8
In 12/8 the metronome clicks every eighth note. The tempo number still counts quarter notes, so you hear twice as many clicks as the number says: at 75 bpm that is 150 clicks a minute. The big beat you tap your foot to is three eighth notes long, so it moves at two thirds of the number: 50 beats a minute at 75 bpm. For a big beat of 60, set the tempo to 90.
How 12/8 feels
12/8 has a heavy, swaying feel. The four big beats keep it steady like 4/4, and the triplets inside each beat give it the lazy roll of a slow blues.
In a slow blues the drummer usually hits the snare on big beats 2 and 4, which are clicks 4 and 10. Try the backbeat pattern to hear it.

12/8 time FAQ
Is 12/8 the same as a shuffle?
They are close relatives. A shuffle in 4/4 plays each beat as a long-short triplet. Written in 12/8, the same groove has the triplets built into the time signature.
What is the difference between 12/8 and 6/8?
A bar of 12/8 is two bars of 6/8 joined together: four big beats instead of two. Songs with longer phrases, like slow blues, are usually written in 12/8.
Why is the tempo number higher than the beat I feel?
The tempo on this metronome counts quarter notes. In 12/8 the big beat is three eighth notes long, so it moves at two thirds of the number shown.
