Two-part Inventions by J. S. Bach, Thematic Hypostases

Johann Sebastian Bach can be considered the greatest pre-classical composer of keyboard instruments, respectively piano, his works being universally present in concert programs. Also, due to his experience as a teacher, the creation of J. S. Bach also has a great pedagogical importance: among the compositions intended for musical education, we mention: Two- and Three-part Inventions (1723). The invention is a small free-form polyphonic composition, written in an imitative style, with a pronounced improvisational character. The two-part inventions that we have focused on (the first six), true jewels in terms of perfection of form, Bach's fundamental works for the piano, do not contain features of outward virtuosity, but music full of content and depth, the various thematic hypostases emphasizing their emotional substance. Another important aspect is the didactic function of this music, Bachian inventions constantly accompanied the training and improvement of pianists, being ideal due to their complexity, for deepening musical thinking.
