Päänivelsestä
Päänivelsestä is a Finnish term that translates to "head joint" in English. It most commonly refers to the upper section of a flute. In a modern Boehm-system flute, the instrument is typically made in three parts: the head joint, the body, and the foot joint. The head joint is the part of the flute that the player blows into. It contains the embouchure hole, which is the opening across which the player directs their air stream to produce sound. The shape and material of the head joint significantly influence the flute's tone color, response, and intonation. Head joints can be made from various materials, including wood, metal alloys, and sometimes even combinations of materials. Different head joint designs can offer varying degrees of resistance and tonal characteristics, allowing flutists to personalize their instrument's sound. The precise fit between the head joint and the body of the flute is also crucial for maintaining airtightness and proper intonation. The head joint's length and bore shape are key factors in determining the instrument's overall pitch and tuning.
