224 lines of the choral as a canto fermo at such points as may be found most convenient. A fugue of this kind is very seldom strict as to the intervals of entry. Of the numerous specimens to be found in Bach's 190 Church Cantatas, there is not a single one which would not be more accurately described as a fugato with a choral. As these have nearly always an independent orchestral accompaniment, we prefer to select as an illustration the first twenty bars of a fugue on a choral taken from one of the motetts. The movement is too long to be quoted in full.
