Gralla

Overview

The gralla is a traditional Catalan woodwind instrument: a small wooden double-reed shawm with a conical bore, seven finger holes, and a single thumbhole. Its sound is loud, bright, and slightly nasal, designed to carry over large crowds at outdoor festivals. The gralla typically plays in pairs or in larger groups (colla de gralles), almost always accompanied by a timbal drum.

Origin & History

Shawm-type wind instruments have been played across the Mediterranean for many centuries, and the gralla is the Catalan branch of that family. It is documented in Catalan civic music from at least the seventeenth century and probably earlier. After a period of decline in the twentieth century the instrument has experienced a vigorous revival, supported by community music schools and by the resurgence of traditional Catalan festivals.

How It’s Played

The player blows into a small double reed at the top of the instrument, controlling pitch with the seven finger holes and the thumbhole. The reed and conical bore together produce the characteristic loud, penetrating tone. Playing usually requires “circular breathing” for sustained passages, and a strong embouchure to maintain steady pitch and dynamics outdoors.

Cultural Significance

The gralla is most strongly associated with two pillars of Catalan public culture. The first is the castells tradition, in which teams build human towers up to several storeys high; gralles play specific tunes that mark the stages of construction. The second is the wider world of festes majors – town festivals featuring giants, big-headed figures, and processions, where the gralla and timbal provide the musical backdrop.
