Spitta (ii. 620, 718) mentions a Birthday Cantata written in 1717-1721(?), the title of which is lost.
The references are to Peters' edition.
The D minor contains the famous Chaconne.
The references are to Peters' edition. In the B.G. edition the Orchestral music is included in the Chamber Music volumes.
Pirro, p. 228, holds that the first two (C major and B minor) were written at Cöthen and the last two (D major and D major) at Leipzig. Schweitzer (i. 402) regards it as not clear in which period the Overtures were written.
In A minor, E major, G major. The G major figures as the fourth Brandenburg (bk. 264) and as the Clavier Concerto in F major (bk. 248). The A minor and E major were also converted into Clavier Concerti (G minor and D major) (bks. 249, 251). The D minor Clavier Concerto (bk. 264) preserves a lost Violin Concerto in the same key, and the one in F minor (bk. 250) corresponds with a lost Violin Concerto in G minor (bks. 3068, 3069).
Also arranged as a Concerto for two Claviers (C minor) in P. bk. 257b.
Bach wrote another Magnificat, the music of which is lost. See Spitta, ii. 374.
All except the Sanctus in D major are of doubtful authenticity. See Schweitzer, ii. 328 and Spitta, iii. 41 n.
The Concerto in C minor (P. bk. 257) is an arrangement of one for two Violins now lost. The third, also in C minor, is identical with the D minor Concerto for two Violins and is published in that key in the Peters edition. The remaining Concerto, in C major, is the only one originally written for the Clavier. See Schweitzer, i. 413.
