Tacked onto the end of the third book of Clavier-Übung
(Keyboard Practice), his monumental compilation of
music for harpsichord published in 1739, the Duetto (4)
of Johann Sebastian Bach (1675-1750) are in essence
two-part inventions. The first Duetto in E minor, BWV
802, features invertible counterpoint and imitative
textures. The work opens with a statement scale-like
theme in the right hand with a simple accompaniment in
the left hand followed by the theme in the left hand
with the accompaniment in the right hand. The first
development section is imitative counterpoint between
both hands, followed by the second statement of the
theme as a canon in both hands. The second development
for both hands is fuller and more detailed, followed by
the third statement of the theme in a more elaborate
form for both hands. The third development section
features the opening phrase of the scale-like theme for
both hands, followed by a fourth and final statement of
the theme spread in imitation between both hands before
the final cadence.

Although originally composed for Harpsichord, I created
this arrangement of the Duetto No. 1 in E Minor (BWV
802) for Oboe & Cello.
