The number is 4895 and 4986 ( only for foot joint ).

This model is based 4895 and 4986’s foot joint. So, its pitch is a little lower than one with 4895’s foot. and it can sound at about 415Hz with my tuning method.

4896’s foot joint has only 1 key and High D# is too sharper.
Probably All flute traverse have too sharp high D#.
Quantz thinked the flute traverse need a key and tone hole to sound high D# at correct meantone intonation,
I think that this Quantz key on the flute traverse after Kirst may not be used to attack D# on all range.
Because the tone hole of original is too small and the difference of Eb is very wide.

Next photo, The foot joint has 2 keys. One is normal key for Low and Middle Eb and D#, the other is Quantz key for high D# and Eb. This may be Kirst’s way.

I tuned them with my tuning method. We can play all 24 keys with Hotettere fingering. And it isn’t available to use alternative joint except No.1 of 4985.

The surviving ones (no.4895 and 4986 and 473) don’t have Quantz key. Only the no.118 at Bate collection has the 2 key on the foot joint.
These are Silver keys which are casted.
I also use casted keys.

A surviving original flute traverse no.473 at Überschrift: Staatliches Institut für Musikforschung has tuning slide.
I tried this for some years. Then I think it aren’t needed.

The flute traverse after F.G.A. Kirst sometime has foot register tuning system. The length of Foot joint on No.4895 does not have enough resonance with the longest corp on No.4986.
If this longest corp is used, It will need more longer foot joint.

I tried making some Kirst’s foot joint.
The left one is based on No.118 @ Bate collection.
The center one is No.4986.
The right one is No.4895.
The left one has less resonance.
To play at 415hz, it is better longest one.
To play at more higher pitch, shotest one is good.

I tried making this flute with kingwood or Ebony, However these flutes does not sound on. So I only make it from Grenadilla. Grenadilla wasn’t used to make woodwind in baroque period. I think the reason is the wood’s hardness too high. The ivory was used for woodwind in the period. But Nowaday it isn’t easy to get the material and it shrinks more than hard wood.

Option

  • imitation ivory balusters
  • Head screw
  • Quantz key
  • Silver keys
