Three-holed pipes for one-handed playing are known in many parts of the world since Medieval times. Tabor-Pipes and Txirula/Txistus have two finger- holes in front and one thumb-hole in the back. The instruments are designed to be played with one hand, so that the other hand is free to play a tabor-drum, a stringed-tambour, or hurdy-gurdy. The only difference between a Tabor-Pipe and a Txirula or Txistu is the diameter and position of the three tone holes and the musical scale resulting from that difference. Both types can produce a contiguous scale of one octave and a fifth, ample range for any folktune!
Some people manage to play two 3-hole pipes simultaneously. It is possible to play contiguous scales because the pipes are designed to allow the playing of a series of five or more harmonics, using the three tone-holes only for filling in those notes that are not part of the harmonic series. The Tabor-Pipe plays a major scale beginning with a sequence of: whole-tone, whole-tone, whole-tone.
The Basque Txirula / Txistu plays a Dorian scale beginning with a sequence of: whole-tone, whole-tone, semi-tone. The useful contiguous scale always begins on the first harmonic, one octave higher than the fundamental. A thumbrest, fingering chart, joint grease and a vinyl carrying pouch are included in the price of the Garland Tabor-Pipes.
