Sinfonias (Three Part Inventions 1, 9 & 13) for Three Trombones by J.S. Bach, transcribed by Ralph Sauer, pub. Trigram

Item Details

Ralph Sauer has transcribed three of Bach's 3-part inventions (originally written for keyboard).

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 originally written as musical exercises for his students.
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.
