The Basque txistu is a fipple flute with three finger holes. The sound produced by txistus depends on the physical characteristics of the instrument and the control exerted by the player. Cross fingering and half holing methods are used to play over two octaves. The effect of the horizontal position of the metal labium W, is experimentally measured in this paper. The studied notes are measured with a blowing machine, recording the radiated sound for a known input pressure and also with a musician playing them in mezzo forte dynamic. Data produced by a traditional and a new txistu prototype have been collected, analysed and compared. The internal bore shape of this new txistu is not pure cylindrical as that of the traditional txistu. Moreover the location, size and height of the holes have been changed. The analysis shows remarkable tuning differences between the two txistus.
