Keys and Modulations in the Two-part Inventions of Johann Sebastian Bach
An illustration of the keys and modulations in all fifteen of J. S. Bach's TWO-PART Inventions. This worksheet identifies the chords on each note of the scale of each piece, based on the key of each Invention. It also confirms Bach's awareness for modulation of the 'six closely-related' keys. A remarkable fact that throughout the Inventions, Bach was able to restrict modulation to the keys based upon the chords I - VI.
