Sonate D-Dur, WV 513 for flute and and basso continuo

Georg Christoph Wagenseil (1715–1777) was an influential Austrian composer, keyboardist, and teacher who served as a pivotal link between the Baroque and Classical eras in Vienna.
A lifelong resident of Vienna, Wagenseil became a court composer for the Habsburg Empress Maria Theresa in 1739. He held this prestigious position for nearly 40 years until his death. He was the keyboard instructor to the Empress’s daughters, including the future Marie Antoinette.
Wagenseil was highly regarded throughout Europe. He was a virtuoso organist and harpsichordist. His keyboard concertos and sonatas helped transition the harpsichord toward the early fortepiano. When the six-year-old Wolfgang Amadeus Mozart performed for the Empress in 1762, he famously asked for Wagenseil to be present at the keyboard to turn pages, acknowledging him as a master of the craft.
Wagenseil was a pioneer of the Galant style, which replaced complex Baroque counterpoint with light, elegant melodies and clear phrasing. He is also credited as a founder of the Viennese Pre-Classical School. His early symphonies (numbering nearly 100) were instrumental in developing the four-movement symphonic structure later perfected by Haydn and Mozart.
