Editing Johann Friedrich Agricola (section)

===Author===
In 1754 he co-authored, with [[Carl Philipp Emanuel Bach]], [[Bach's Nekrolog|J. S. Bach's obituary]]. His 1757 ''Anleitung zur Singekunst'' (''Introduction to the Art of Singing'') is a translation of [[Pier Francesco Tosi]]'s 1723 treatise ''Opinioni de' cantori antichi e moderni'' with Agricola's own extensive comments. He edited and added extensive commentary to the 1768 (posthumous) edition of [[Jakob Adlung]]'s ''[[Musica mechanica organoedi]]'' ([http://digitalcommons.unl.edu/zeabook/6/ English translation]). His annotations are considered an important source of information on J. S. Bach's views on the [[fortepiano]] designs of [[Gottfried Silbermann]], on the [[lute-harpsichord]], and on organ building.<ref name="Jones1999">[[Richard D. P.
