Hautboy ( classical oboe ) after J.F.Grundmann @ Bruxelles

The original of this hautboy is at Musical instrument Museum at Bruxelles and the number is 2331.
The original has 4 keys that are G#, F, Eb, C. I think that it did not have G# and F keys firstly.

I noticed the bell needs bell peg. by that the hautboy sounds lowest C with more better intonation.

My bell peg’s design is based violin’s peg but it is more simple.

I think that this oboe needs wool mute inside the bell.
Because without any mutes, the lowest C is too louder.
and the rim which inside of edge of bell work to stay wool mute.
Bell peg and wool mute gives more better lowest C.
it is easier to play oboe quartetto by W.A.Mozart.
Wool mute is in the edge of bell

I tried some reed style. Now I think that vienne style is good for hautboy after Grundmann.
