The txistu (flute) and the tambourine are the usual instruments used to provide the music for the brokel-dantza. Txistu and tambourine are a Basque version of the  pipe and tabor duo traditionally used in numerous European regions. In the 17th and 18th centuries, the txistu underwent a unique development in Euskal Herria. An attempt was made to standardise it to more cultured musical forms, by changing the dimensions of the instrument until it was brought in line to the scale of the chamber orchestra of the period.

The result of this change was precisely the step that was given to complete the instrumental family of the txistu with the creation of the four-member txistularis group. In that quartet, two people played the txistu and the tambourine, a third person played a longer txistu called a silbote and the fourth played the atabal or drum. Nonetheless, the simple formula consisting of one person playing both instruments that more effectively helped to spread the txistu and tambourine continues to be popular.   This type of txistularis have frequently played together with an atabalari. The two aforementioned options - a duo of txistulari and atabalari, and quartert - are suitable for providing the music for the brokel-dantza.

In the same way that each of the dances making up the brokel-dantza can have a different origin and can be danced on different occasions, the accompanying music is also very varied. For example, it is thought that the choice of the zortzikos that usually preceded the sets were left to the choice of the tambourine player, which means that there would be a varied repertory of melodies from which to choose. The melodies that Isidro Ansorena, the txistulari, wrote down in 1924, in response to a request by the San Sebastian Academy Txistu and dance, are the ones that have been most widely used during the 20th century, even though José Ignacio Ansorena recommends that each txistulari chooses the ones he prefers and which are better adapted to his technique.

José Ignacio Ansorena and Javier Hernández Arsuaga have published some scores of melodies suitable by the brokel-dantza in the specialist journal, Txistulari-Dantzariak, accompanied by some observations on them.
