The Inventions and Sinfonias, BWV 772–801, also known
as the Two- and Three-Part Inventions, are a collection
of thirty short keyboard compositions by Johann
Sebastian Bach (1685–1750): 15 inventions, which are
two-part contrapuntal pieces, and 15 sinfonias, which
are three-part contrapuntal pieces. They were

Bach titled the collection: "Honest method, by which
the amateurs of the keyboard – especially, however,
those desirous of learning – are shown a clear way
not only (1) to learn to play cleanly in two parts, but
also, after further progress, (2) to handle three
obligate parts correctly and well; and along with this
not only to obtain good inventions (ideas) but to
develop the same well; above all, however, to achieve a
cantabile style in playing and at the same time acquire
a strong foretaste of composition."
The two groups of pieces are both arranged in order of
ascending key, each group covering eight major and
seven minor keys and were composed in Köthen; the
sinfonias, on the other hand, were probably not
finished until the beginning of the Leipzig period.

Although originally composed for Harpsichord, I created
this arrangement of the Sinfonia No. 13 in A Minor (BWV
799) for String Trio (Violin, Viola & Cello).
