PHOTOGRAPH AND NOTES ON WOOD PICCOLO HEAD JOINT
The above Wood Piccolo headjoint was made by Robert Bigio, flute maker in the UK, who kindly gave me permission to reproduce his photograph
The paragraph below is a direct quote from Robert Bigio's Web Site
My piccolo headjoints can be made to fit any instrument. As with my flutes, I try to make my piccolos sound rich and warm. I have found the best sound to come from an embouchure shaped like those on Rudall Carte piccolos from the early years of this century. As you can see from this picture, the embouchure hole on my piccolo heads is oval, rather than rectangular as is common today.
The above photograph and notes are as accurate as my knowledge of the subject permits
