Wooden head joint, baroque embouchure hole: historical sound and fingering efficiency. Each of my flute head joint is handmade. the embouchure is made with a special under engraving that gives a special and individual sound signature to each flute head joint. Each head joint has a conical bore that gives it absolute accuracy in all octaves I select my woods carefully from the preferred part of the wood only. The wood has undergone natural drying for decades, which gives it a uniform density and a long-term strength.
