Bach cantatas (Teldec)

J. S. Bach - Das Kantatenwerk is a classical music recording project initiated by the record label of Telefunken in 1971 (first recordings have been made in December 1970) to record all 193 sacred Bach cantatas. The project was entrusted to Nikolaus Harnoncourt and Gustav Leonhardt. Each conductor had his own instrumental ensemble, based in Austria and the Netherlands respectively.

The project was the first attempt at a complete recording of the sacred cantatas, but Harnoncourt and Leonhardt were still working on the cantatas when a project which started later, led by Helmuth Rilling, Gächinger Kantorei and Bach-Collegium Stuttgart completed a recording of the sacred cantatas and oratorios on Bach's 300th birthday, 21 March 1985. Since Rilling recorded on modern instruments the Telefunken (then Teldec) project could at least claim, when the project completed in 1990, to be the first recording using historical instruments, with boys' choirs and boy soloists for most soprano and some alto parts. An exception to the use of male voices was made for cantatas nos. 51 and 199, which were intended for a female soprano voice.

Harnoncourt conducted his Concentus Musicus Wien with either the Wiener Sängerknaben or the Tölzer Knabenchor . Leonhardt conducted his Leonhardt-Consort with the Tölzer Knabenchor, Knabenchor Hannover and the adult Collegium Vocale Gent.

Shortly before the project finished Telefunken sold the Teldec label to Warner in 1988.
