What is a ground bass? A theme or tune stated repeatedly and continuously in the lowest voice.
If that sounds tedious, just listen to the magic Bach performed above the ground. One theme embroidered and embellished with magnificent, mysterious, awe-inspiring figurations each radically different from the rest, yet organically intertwined and perfectly related to the whole.
The Fugue takes the main theme and develops it further by repeating it at different levels with accompanying counterpoint in each voice then moving it through a variety of keys with different "episodic" material heightening the intensity each time till it returns to the original key
and comes to a grand climax.
The hideously overworked term "AWESOME" must have been invented to describe the great organ works
of Johann Sebastian Bach.
Helmut Walcha, the great German organist, was blinded at age nineteen. Nevertheless he continued his studies and mastered the complete organ works of J.S. Bach and many other masterworks for the instrument as well. His recordings are among the very finest ever made of these marvels of ingenuity, complexity, wonder, glory, mystical significance and deep commitment to faith in Our Lord, Jesus Christ.
