I wrote about my first replica after Thomas Lot III based on surviving original at Dayton Miller flute collection in Washington in this my web site before. Baroque flute after Thomas Lot III @ Washington
This time, I made my second replica of baroque flute after Thomas Lot III. I used measurements of surviving originals by Lot III (no.1139) and Delerablee (no.1138) belongs to Bate collection in Oxford. When I visited the collection in 2011, I research Delerablee’s baroque flute and the other one by Lot. Especially Delerablee’s kept good condition. I was very surprised with that I can play it with pianissimo and forte easily. Because I had already noticed the measuerment of undercut for embouchure is smaller than surviving one. So I decided me to study baroque flute after Lot again.
- Upper one is new made one. The upper joint was designed by myself. The length from shoulders is 172 mm. sounds at 402 Hz. Head cork position: 24 mm. The octave of Low and Mid G is wider.
- below one is old made one and it was re-tuned in this time. The length from shoulders of the upper part 179 mm. sounds at 399 Hz. Head cork position 20 mm. The octave of Low and Mid G is a little wide.
The undercutting of tone holes of these my replicas isn’t wide like surviving original. The widest measurement of the diameter is 10 mm at the base. When I tuned them, I observed how much undercutting makes different. 9 mm at 1st tone hole makes special character of the sound. I have already known that too wide undercutting lost focus of the tone. I enlarge to get enough good intonation on each tone, I didn’t get very large undercutting yet.
On upper one, the octave of Low G (-20 cents from equal temperament) and Mid G(+20 cents) is wider. Large undercutting of 4th hole isn’t needed absolutely.
Both head joints has same measurements of embouchure and the the position. I think that the surviving original by Delerablee(no.1138) belongs toBate collection has good measurement about diameter of the embouchure. Only the diameter of the bore is different. One based Dayton has larger bore than one based Bate.
This time, I made new foot based on Delerablee’s. The length is same to Lot’s. Those bore dimension are different.
How does it affect to the sound ?
The foot by Delerablee’s flaten the pitch 1~2Hz and makes dark sound. The foot by Lot based on Dayton’s raises the pitch 1~2 Hz and makes open sound.The other foot by Lot has the other dimesion of bore. The bore of the foot can be used to adjust + 1~2 pitch. When Delerablee was Master of his shop, dark Sound might be liked by people.
