Johann Sebastian Bach: His Life, Art, and Work

by Johann Nikolaus Forkel

A fingered exercise.

The Appendices of the volume contain variant readings of movements elsewhere contained in it, and of the first, third, and sixth Preludes and Fugues in the second part of the “Well-tempered Clavier.”

See B.G. XLV. (1) Appendix.

Only nos. 2 and 3 are derived from Vivaldi.

A variant text is in B.G. XLII. 282.

Vivaldi's text of the first movement is in the Appendix (p. 229).

See B.G. XLIII. (2) sec. 1 no. 2.

The fugal subject is taken from the Allabreve.

Bach's instrumental accompaniments are in the Appendix (p. 143).

C. P. E. Bach's collection of his father's Choral settings was published by Immanuel Breitkopf in four volumes between the years 1784-87. They are all inoluded in Breitkopf and Haertel's edition (1898) of Bach s “Choralgesänge”; the numerals in brackets in the above list indicate the position of each Choral in that collection. The latter includes also the simple four-part Chorals from the Oratorios and Cantatas; hence the numeration of that volume and B.G. XXXIX. is not uniform.
