I am wondering if some of the more intense flute buffs here can help with some flute history questions. I am looking for information on the foot joint for the C note on a D flute. Which came first: the D flute and then the foot joint to get a C flute, or was there always a C foot joint that later got removed for a D flute? At what point did wooden flutes start getting broken down into jointed parts? Any good references you can recommend?
Thx,

This guy seems to have a handle on it, there is more content on the site also that is interesting.
Good luck on your search!

Another wonderful site for historical flute information is
By the way, I agree that the Standing Stones site is excellent as well!

Thanks. This ought to keep me off the streets for a while.

Early flutes were in D (at least nominally–the actual pitch varied). In the seventeenth centruy, the idea of adding “extra” keys was invented, in order to lose the ugly cross fingerings. I believe the first was D sharp, because that isn’t possible any other way. Hammy has the actual sequence in his book, but the foot notes were later. When you think about it, when you only have fingers (no keys), it’s impossible to have a C foot.
