THE C# TRILL KEY
U.S. Patent 7,589,268B2
Over the years, many players have asked about the possibility of having a C# trill key on the conical piccolo. After all, the C# trill is one of the most useful and popular additional mechanisms on the flute. After years of working on this problem, we are very pleased to be able to offer a C# trill mechanism for Keefe Piccolos. Our C# trill produces all of the standard trills found on flutes with a C# trill key, including the high G to A trill.
Until now, when asked to trill high G to A, piccolo players have had the option of choosing from a number of problematic fingerings, or simply trilling from G to G#. To produce the G to A trill, we have added a key that allows the player to trill the G# key in combination with the C# trill key (this G# trill key is operated by the first finger of the right hand). Trilling the G#/C# trill mechanism in combination with the upper trill key produces a true G to A trill.

Keefe Piccolo Company has published a fingering guide detailing all the trills related to the C# trill key. You will find it here: Keefe Fingering Guide
