Kirst 415

Let me first simply copy the Kirst
description from the New Langwill index [1].
Kirst, Friederich Gabriel August, (not completely sure) Born Dresden 1750, Died Berlin 29 April 1806.
Flute maker in Potsdam from 1772 to 1804.
Probably son of Johann Georg Kirst, inspector of municipal waterworks in
Dresden.
Apprenticed to A Grenser, Dresden 1768/1770. Working for C.F.Freyer in Potsdam.
In 1772 he married Freyer's widow after Freyer died and took over his workshop
as master.
In 1772 he was also granted 'privilegium
privatum' to supply the entire Prussian army with woodwind instruments. Nicolai
(1779) reported that flötenmacher Kirst (im Holländischen Revier) bekommt Gehalt
vom Könige (woodwind instrument maker Kirst (in the Dutch quarter)receives a
salary from the king).
There were a number of apprentices
in his workshop; J.G. Martin, I.C.H.Müller, A.F.Piering and J.W..Weisse.
In 1804 the workshop was taken
over by his stepson J.G.Freyer, this changed later to Freyer and Martin.
It is most likely both from the
extant instruments and form the fact that the workshop was in Potsdam that there
was a cooperation between Kirst and Quantz.
So far a slightly reorganized copy
from the Langwill index.
The Kirst 415 is a copy of the original owned by Christoph Huntgeburth, the well known player and conservatory teacher in Berlin. The original is a bit too low and has a slightly problematic intonation, as many originals do. I have first, as I always do made a precise copy of this original and then recalculated the pitch a little bit. I retuned as I always do such that now the flute is easy to play.
It is a traverso that is at the same time extremely powerful and beautifully flexible with respect to dynamics. I would say that it is as powerful as the traverso's nowadays acquired for this reason but it can be played piano easily and beautifully as well!
As this is a second half eighteenth century instrument as one would expect the third octave is easy although it needs a few special fingerings to be in tune.
This must have been a flute made very soon after Kirst took over from the deceased Mr. Freyer. The old Mr. Freyer probably still made basically first half eighteenth century traverso. So this flute has nice second half eighteenth century properties such as an easy third octave but it also still has the warmth of the first half of the eighteenth century. Therefore music from the beginning of the eighteenth century till the end can very well be played on it. Later Kirst flutes tend to be primarily brilliant.
So, even though this is a second half eighteenth century flute the professional players owning one are inclined to play everything on it because it certainly has that possibility.
Some special fingerings for the third octave
f#3 14key open, so f with the second finger off. The quantz fingering is too low.
g3 136keyopen at choice, makes also change to d3 easier because the key is open
g#3 6key open,
