Johann Gottfried Walther


Johann Gottfried Walther was a German music theorist, organist, composer, and lexicographer of the Baroque era.
Walther was born at Erfurt. Not only was his life almost exactly contemporaneous to that of Johann Sebastian Bach, he was the famous composer's cousin.
Walther was most well known as the compiler of the Musicalisches Lexicon, an enormous dictionary of music and musicians. Not only was it the first dictionary of musical terms written in the German language, it was the first to contain both 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 evidently drew on more than 250 separate 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.
Some further information on Walther can be found in the book Musica Poetica by Dietrich Bartel. On page 22, Bartel quotes Walther's definition of musica poetica, or musical rhetoric, as:
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. 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 exactly 132 organ preludes based on Lutheran chorale melodies. Some free keyboard music also belongs to his legacy.
