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.

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] 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.

[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.
