The Two-Part Invention No. 1 in C Major, BWV 772, is the opening work of J.S. Bach's celebrated collection of fifteen two-part inventions, composed around 1720. Originally written for the musical education of his eldest son Wilhelm Friedemann Bach, this piece serves as an ideal introduction to the art of two-voice counterpoint.
The invention opens with a memorable ascending scale motif that becomes the foundation for an intricate dialogue between the two voices. Through invertible counterpoint, Bach demonstrates how a single musical idea can be developed, inverted, and exchanged between hands to create a complete and satisfying musical structure. The simplicity of C Major allows the contrapuntal writing to shine without the added complexity of sharps or flats, making it the perfect starting point for the collection.
As perhaps the most widely recognized of all the inventions, BWV 772 remains an essential study piece for developing independent hand coordination, articulation, and an understanding of Baroque counterpoint. Its elegant simplicity and pedagogical brilliance continue to make it a cornerstone of piano education worldwide.
