Johann Gottfried Walther: Notes and Commentary

Johann Gottfried Walther, the cousin of Johann Sebastian Bach’s son, was a German music theorist, organist, composer, and lexicographer of the Baroque era. He was most well known as the compiler of the Musicalisches Lexicon (Leipzig, 1732), the first dictionary of musical terms written in the German language and the first to contain terms and biographical information about composers and performers up to the early 18th century. In all, the Musicalisches Lexicon defines more than 3,000 musical terms. Walther is thought to have drawn on more than 250 sources in compiling it, including theoretical treatises of the early Baroque and Renaissance. The single most important source for the work was the writings of Johann Mattheson, who is referenced more than 200 times.

In defining musical composition, Walther described it as a form of mathematical science. “Musica Poetica or musical composition is a mathematical science through which an agreeable and correct harmony of the notes is brought to paper in order that it might later be sung or played, thereby appropriately moving the listeners to Godly devotion as well as to please and delight both mind and soul,” he wrote. “It is so called because the composer must not only understand language as does the poet in order not to violate the meter of the text but because he also writes poetry, namely a melody, thus deserving the title Melopoeta or Melopoeus.”

Walther was the music teacher of Prince Johann Ernst von Sachsen-Weimar. He wrote a handbook for the young prince with the title Praecepta der musicalischen Composition, 1708. It remained handwritten until Peter Benary’s edition (Leipzig, 1955). As an organ composer, Walther became famous for his organ transcriptions of orchestral concertos by contemporary Italian and German masters. He made 14 transcriptions of concertos by Albinoni, Gentili, Taglietti, Giuseppe Torelli, Vivaldi and Telemann. These works were the models for Bach to write his famous transcriptions of concertos by Vivaldi and others. On the other hand, Walther as a city organist of Weimar wrote 132 organ preludes based on Lutheran chorale melodies. He lived from September 18, 1684, to 23 March 23, 1748. —Excerpted from Wikipedia
