How it works
An 11/8 metronome counts the eighth note, eleven to a bar. This one opens on 3+3+3+2, a grouping people look for by those numbers; Wikipedia's Undecuple meter article counts nine ways to break eleven into twos and threes.

Questions and answers
How do you count 11/8 as 3+3+3+2?
One two three, one two three, one two three, one two, with a fresh one at every raised click. Wikipedia's Time signature article spells out a grouped bar of eight the same way, starting again at one for each group.
Is 3+3+3+2 the only way to group 11/8?
No. The Undecuple meter article says eleven is usually subdivided into twos and threes and offers 2+2+2+2+3 as its example. Three threes and a two is another order that arithmetic allows, and the only one this page clicks.
What music is in 11/8?
The kopanitsa, for one: a family of brisk line dances of western Bulgaria whose rhythm Wikipedia's article on it gives as quick, quick, slow, quick, quick, counted 2-2-3-2-2. That is five beats where this pad marks four; this site's 11/16 metronome marks all five.
Why is 11/8 called a complex time signature?
Eleven is a prime number, the reason the Undecuple meter article gives. No bar of eleven splits into equal twos or equal threes, so it mixes them. On this pad that makes four beats to the bar: three long ones, then a short one.
Why can't I hear the metronome?
A phone has three usual ways of hiding it: a ring switch flicked to silent, a volume slider at the bottom, or Bluetooth headphones still connected. The eleven dots carry on regardless, with the first, fourth, seventh and tenth larger.
