Homilius's choral preludes are rooted in the contrapuntal tradition propounded by his teacher Bach; not, however, without characteristics belonging to the more affective aesthetic movement of Empfindsame Stil for which Bach's son CPE is now best known. Thus there are some bold modulations which Father Bach would never have imagined or countenanced, such as the oscillation between C minor and C sharp minor in Ach Herr, mich armen S�nder, or the (then still) unusual B flat minor key of Wer nur den lieben Gott l�sst walten. This appears to be the first recording to include all the great organ chorales so far authenticated as the work of Homilius - many of them remain unpublished. It is made by a Venetian keyboard musician specializing in early music, on a modern (2007) instrument tuned to Werckmeister III - as close as is practicable to the tuning that Homilius would have known.
