Powerful vocal quartet with roots in various traditions, bears fruit in many languages.

Tetra is a powerful Swedish vocal quartet performing in a variety of genres and rooted in different origins.
Four female vocalists from Gothenburg, Sweden with a common desire to share our songs with each other established Tetra in 2006.

We are all experienced in performing songs from a wide range of folk music traditions.

In our music, you will encounter the ornamental vocal styles of Arabic and Greek music, Caribbean pulses, and Scandinavian groove. We perform our own arrangements, based on rhythmic vocal accompaniment, diversity of vocal range, and percussion.

In Tetra, we dance and play on our journey through vocal traditions from many parts of the world. The results are a distinctly Tetra experience, with drumming, voices singing in parts, improvisation and dance.

Join us in the magical, musical world of Tetra, where beautiful instruments and songs in languages from north, south, east and west meet.

"The very best listening of all, although it doesn't happen very often, is when your chin drops and you absorb the sound through your mouth as well as your ears. That's what happens, spontaneously, when theTETRA vocal ensemble take the stage, sort of sauntering into song and allowing it to form as they go along.

The bombo is a throbbing heartbeat, the shamanic drum, accordion, vocal ornamentation based on collages – layer upon layer – with room for the vocalists' own compositions, setting fragments of poetry to music, and with melodic outbursts right when the music gets heaviest. Does it sound overwhelming? It is, and it still makes you want more..."
