Of course not all of Bach's music was strictly contrapuntal. The Concerto For Oboe d'Amore has the solo instrument play a melody with as much as against the string parts. Like all of Bach's concertos, there exists different versions of the work for different instruments. This concerto also exists in the form of a harpsichord concerto, but unlike most of Bach's other concertos it was not originally written for violin. There has been research done by Sir Donald Tovey proving that the concerto was originally written for the oboe d'amore. The harpsichord version is the only one extant, but with the evidence supplied by Tovey the solo part was reconstructed from the harpsichord part.
The concerto for oboe d'amore has the traditional three movements:
I. Allegro - Bach has the full string orchestra play the opening of the concerto. The oboe d'amore adds its melodic statements in between the returning motive played by the strings. The movement has the grace and balance of a dance between the two.
II. Allegretto - The difference between the opening movement and this one is like day and night. Where the mood was carefree and light, it has now turned sad and melancholic. The oboe d'amore plays one of Bach's most emotional, heart-felt tunes while being accompanied by a chromatic descent in the bass.
III. Allegro ma non tanto - The finale returns to the feelings of a dance and happier times.
