BWV 783 Invention No 12 by Johann Sebastian Bach (1685-1750)
It is believed that Bach’s intention was to bring the 15 inventions together as a single work along with his three-part piece known as the Sinfornias, confirmed by the way that they are presented in a manuscript penned in his own hand in 1723. These inventions demonstrate contrapuntal technique and explore musical expressions while developing motids in a logical fashion.
Bach use the term “invention” as a play on words. In today’s musical practice, invention pertains directly to this body of work; however, Bach uses it to describe an idea that could be used as a compositional theme with the intention that this type of technical exercise could inspire those who studied these pieces to develop a more musical approach.
