History: 

• Johann Joachim Quantz (1697–1773) was the best-known flute player of the 18th century. A prominent figure in the 18th century music scene. Quantz was renowned not only for his compositions and the influential book "On playing the Flute" (published in 1752), but also for his role as the esteemed flute instructor-teacher to Frederick the Great of Prussia starting from 1728.
• A Treatise on Traverso Flute Playing. This invaluable resource, published in 1752, offers insights into performance practice and flute technique from the 18th century. Its enduring value makes it relevant for enthusiasts and musicians seeking historical perspective.
• Of the eight complete flutes that survived are all from the collection of Frederick the Great.

Invention of Tuning Headjoint & Eb Key: In 1739, Quantz embarked on groundbreaking research in the realm of flute-making, contributing to the evolution of the instrument's design and capabilities.

• Quantz's legacy includes the introduction of the tuning headjoint, often called the "slide headjoint" or "swan neck." This innovative feature allowed flutists to finely adjust the flute's pitch by moving the headjoint, a breakthrough that significantly enhanced intonation across different keys and has persisted in modern flute design.
• Quantz's ingenuity extended to the addition of the Eb key. This pivotal inclusion facilitated effortless execution of the Eb note, elevating overall playability and enabling smoother transitions between notes. The Eb key remains a testament to Quantz's commitment to advancing flute technique.
