Humppa is a type of music from Finland.
It is related to jazz and very fast foxtrot, played two beats to a bar (2/4 or 2/2).
Typical speed is about 220 to 260 beats per minute.
Humppa is also the name of a few social dances danced to humppa music.
All dances involve bounce that follows the strong bass of the music.
In Finnish language, the word humppa can also be used for all social dancing.
The name humppa was invented by Antero Alpola for a radio show in the 1950s. He picked it up from German Oktoberfest where the locals used the word to describe the playing of the band. The band probably used a tuba, as the sound of tuba on the first beat is like hump, the second beat coming as a pa. (The related German style is known as oompah.)
One form of Humppa dance is related to one-step, which arrived in Finland 1913. In this kind of humppa, both dancers take a step on each first beat (on "hump") and progress to the direction of dance. This is danced making turns in closed position or making figures by changing various open positions. The second Humppa form is related to two-step, which came to Finland in 1910. This Humppa has some rhythm and movement from samba and waltz.
A third form of dance, Nilkku, is based on a slow, slow, quick, quick rhythm. The first quick step hardly takes any weight and gives the dance an appearance of limping.
