Jack Moore (1929-2018) worked at Armstrong Flutes in Elkhart, IL. While at Armstrong, he pioneered their Heritage line of professional flutes before starting his own workshop.
This flute has been well cared for and has had minimal use in recent years. The response, sound quality, and pitch are outstanding. The flute plays beautifully in all registers.
John Coltman a renowned physicist and acoustician, developed the first computer-aided
design program for flute scales. This flute features Coltman’s own A=440 design and
offers a remarkably even response and very accurate intonation. His C# design
provides a full-sized tone hole for left-hand C# while keeping a small C# hole as a vent
for middle D and D#, accomplished with a very simple mechanism. This gives a rich,
well-tuned C# in the first and second registers. His special trill mechanism uses a full-
sized D hole (linked to the extra, small touch piece) and a larger-than-usual D# trill
hole. This provides an unusually full, well-tuned C-D trill in both registers, well-tuned
standard trills, and a good high G-A trill using the special D trill only. The D is so good
that it can be used as a primary note to avoid awkward fingerings across registers. The
somewhat large D# trill is linked to both standard trill touches for use on high Bb and B.
This design raises the pitch of the normally flat high Bb while keeping the B well in tune.
Jack Moore has given this flute his pinless mechanism, which provides the same quick,
light feel as the Brögger Mechanik.
