Haskell organ pipe construction

The Haskell organ pipe construction, sometimes known as "Haskelling" is a method of organ construction used when space does not permit the builder to build a full-length pipe. It consists of a shorter (compared to the full-length pipe) tube nested within another shorter tube. This construction, however, subtly alters the tone of the pipe, causing it to adopt a slightly string-like tone. [1] The minimum height of a 16-foot pipe using this technique is around 10 feet. [1]

History

This technique was developed and patented by the William E. Haskell in 1910 for Estey, in a series of patents Haskell took out on techniques intended to reduce the length of organ pipes while maintaining their pitch.[3] Haskell creates several variations on this design. [2] This technique was especially used in the Estey Minuette organs, which had 2MP pipe organs in what resembled rather large grand or upright piano cases.[4]

Uses

This technique is far more commonly used on flue pipes than reed pipes. [2]
