The Kingma System®
A Kingma System® flute is, in all respects, a Boehm system flute with a C# trill. All of the normal touch pieces and fingerings are where you would expect them to be. What makes this flute so unique is that, in addition to the standard Boehm mechanism, there are six extra keys. This is made possible through the use of the patented key-on-key system that has been used so successfully on our alto and bass flutes for many years. These keys are used to produce six of the seven quartertones and multiphonic vents which are "missing" on the normal French model flute. The seventh "missing" quartertone is achieved by using the C# trill key together with the normal C key. The other five quartertones are produced by using the normal, open hole keys.
