This page contains what I will call Schemelli 4-voice chorales, that is, my own 4-voice realizations of the 75 songs for solo voice to which Bach added figured bass, as commissioned by publisher Georg Schemelli in 1736. Bach and Schemelli expected a harpsichord or organ continuo accompaniment according to the figures published, so four-voiced realization was not the intent (although others, apparently including Bach students, and musicians such as the late Sir David Willcocks, have done so, too), and thus sometimes minor modifications to either voice or bass are necessary, so these are not the BGA (Bach-Gesellschaft-Ausgabe) scores.
Realizing a four-voice chorale texture from a melody and bass with continuo figures is not the same task as realizing the latter as continuo per se. In the continuo case, three needed voices each have a degree of freedom, while constrained be consistent with and contrapuntally independent from the bass. In the chorale-building case, the two needed voices have only two degrees of freedom, and must be contrapuntally consistent with not only the bass, but the extant voice. This requires a different technique, and is (of course) more akin to chorale-composing than figured-bass realizing.
As with any figured-bass realization, the composer and realizer share credit in a complex way. You are free to use/share these non-commercially. The numbering system (left column in the table below) is the same as in the Schemelli-songbook of the BGA. Much pleasure on this site! (Do me and yourself a small favor and listen with headphones on please).
All 75 (NEW!) Schemelli chorales for four part mixed voices (made by me) will be added in this table:
