This study reviews technical approaches in the field of Haskell pipe construction and polyphonic pipes. Some of these discoveries reach back centuries and are illustrated with drawings and pictures. Special attention is directed to Haskell construction of pipes. These are tonally based on the principle of adding a so-called helper rank (like the COPULA), because their sound spectra reveal both, the effect of a shortened pipe resonator as well as that of an open pipe at octave pitch. Haskell pipes also relate to bi-phonic pipes, which can produce two notes with the aid of an auxiliary valve. The latter leads to polyphonic organ pipes, which may have a compass of up to nine semitones. The shape of the resonator may change from an elongated pipe to a cuboid, then acting as a Helmholtz resonator. The largest of them have been built as walk-in pipes for demonstration. A final overview comprises technically viable approaches to generate tones of the lowest octave, if space restrictions apply. » weiterlesen» einklappen
