Johann Kuhnau

The Biblical Sonatas, published in 1700, established a legacy for Johann Kuhnau by depicting intricate narratives from scripture through programmatic keyboard music. Though many of his large-scale vocal compositions have vanished, his influence as a polymath and his extended tenure as Thomaskantor in Leipzig define his essential role in the landscape of German Baroque music.

Formative Years and Legal Training

Born in 1660 in Geising, Kuhnau received early musical instruction in Dresden after moving there around 1670. His education encompassed keyboard performance, composition, and the study of Italian and French. Following a return to his home region during a local outbreak of the Great Plague of Vienna in 1680, he pursued further studies at the Johanneum in Zittau and subsequently enrolled at Leipzig University to study law. He began his professional career in 1684, accepting the position of organist at the Thomaskirche in Leipzig, a role he balanced alongside his legal practice after completing his dissertation in 1688.

The Thomaskantor Tenure

In 1701, Kuhnau succeeded Johann Schelle as Thomaskantor, a demanding post he occupied for 21 years until his death in 1722. His tenure involved directing musical activities at the Thomaskirche and teaching at the Thomasschule. Throughout these years, he faced significant professional challenges, including declining health and active opposition from contemporary rivals such as Georg Philipp Telemann and his own former student, Johann Friedrich Fasch. Despite these pressures, he remained prolific in his output of keyboard works and translated various texts from Italian and French into German.

Development of Keyboard Literature

Kuhnau’s published output includes several collections of keyboard works between 1689 and 1700. His Clavier-Übung collections explored major and minor keys through suites consisting of preludes, fugues, and traditional dances. The volume Frische Clavier Früchte, containing six sonatas, proved his most popular work during his lifetime. His contribution to the keyboard sonata is marked by his use of varied textures and his experimentation with the fugue as an extended form. Furthermore, his satirical novel, Der musicalische Quack-Salber, published in 1700, provides a unique look at the contemporary music world through the story of a charlatan posing as an Italian virtuoso.

Legacy and Lost Works

The loss of significant portions of Kuhnau's vocal music, including the opera Orpheus, a Te Deum, and several masses, obscures the full extent of his creative reach. Surviving cantatas, such as the Christmas work Uns ist ein Kind geboren, demonstrate his unified approach to form through the use of instrumental preludes and the alternation of arias and recitatives. Following his death on 5 June 1722, he was succeeded at the Thomaskirche by Johann Sebastian Bach, who faced similar administrative and professional difficulties in the same role.
