The txistu is a three finger holed recorder from the Basque Country. The evolution of the txistu involves different kinds of wood, bore length, finger hole positioning and it being made of two or three pieces. The txistu also has a unique mouthpiece, made up by a small metallic piece of the pipe and also a metal reed which was introduced centuries ago. The distance between the pipe and the reed can be adjusted to fit the user's preferences. By using a blowing machine and data acquisition software, experiments study the influence of the shape and inclination of the reed on the values of the harmonic content and the sonority of the final note.
