[3] A week later, Bach composed the famous cantata for bass solo, Ich will den Kreuzstab gerne tragen, BWV 56, also concluded by a chorale.

[4] Bach used the first movement of the concerto, in da capo form, as an extended instrumental introduction, assigning the solo part to the organ, the tutti to the strings and three oboes which he added for the cantata.

Bach followed the careful wording of the poet by setting the lines from the following aria as a motto and conclusion of each thought as an arioso, the reflection which they frame as a secco recitative.

[2] The repeat of the essential line "Gott soll allein mein Herze haben" "acts like a rondo motif", according to Gardiner.

[1] The music of the aria, marked "siciliano" as the slow movement of the harpsichord concerto, has been regarded as a "farewell to worldly life",[4] in "a mood of heart-stopping intensity",[3] also as a mystic contemplation of a heavenly love.

Conductors have included Rudolf Barshai and Ludwig Güttler and singers Aafje Heynis, Birgit Finnilä, Jadwiga Rappé and Monica Groop.

Andreas Scholl recorded it in 2010 with Julia Schröder leading as concertmaster the Kammerorchester Basel with Junko Takamaya, Michael Feyfar and Raitis Grigalis singing the chorale.
