XV simphonies pour le clavecin - Bach, Johann Sebastian 1685-1750; Forkel, Johann Nikolaus 1749-1818 (Leipzig Peters, 1801)
Early edition
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 "Praeambula" and "Fantasiae" in the Klavierbüchlein für Wilhelm Friedemann Bach, a Clavier-booklet for his eldest son, and later rewritten as musical exercises for his students. The two groups of pieces are both arranged in order of ascending key, each group covering eight major and seven minor keys.
