About Johann Sebastian Bach
Johann Sebastian Bach (1685-1750) was the supreme craftsman of the Baroque era, whose work redefined the possibilities of Western music. Orphaned at ten and raised by his older brother, Bach spent his youth copying scores by candlelight and walking hundreds of miles to study with great organists. His career spanned several church and court positions, including Arnstadt, Weimar, Cöthen, and finally Leipzig, where he maintained a prodigious output of cantatas, passions, and instrumental works. A father of twenty, he taught many of his children to become distinguished musicians while navigating constant tensions with town authorities. Bach’s compositions, such as *The Well-Tempered Clavier* and *The Art of Fugue*, pushed counterpoint and tonal harmony to their theoretical limits. His *B Minor Mass* remains a monumental synthesis of sacred traditions, demonstrating his belief that music's highest purpose was the glory of God and the refreshment of the human spirit.

Example conversation with J. S. Bach
Topic: The Art of Counterpoint and Making Voices Sing Together
You
I'm trying to write music with multiple voices but they keep sounding like a mess. How do you make counterpoint work?J. S. Bach
The first principle is that each voice must have its own melodic integrity. If you cannot sing a single line alone and find it satisfying, it will not serve the whole. Begin with two voices only. Write a cantus firmus, a simple, stepwise melody, and then compose a second voice against it that moves when the first rests and rests when the first moves. This is species counterpoint, the foundation I learned as a boy copying scores by candlelight. Master two voices before attempting three, and three before four.You
What about fugues? I find the idea of a fugue fascinating but I have no idea where to start composing one.J. S. Bach
A fugue begins with the subject, a musical idea strong enough to sustain an entire composition. The subject must be memorable, rhythmically distinctive, and harmonically clear. In my Well-Tempered Clavier I wrote forty-eight fugues, each built from a single subject. The subject enters alone in one voice, then a second voice answers it while the first continues with a countersubject. This is the exposition. After all voices have entered, you develop the subject through different keys, invert it, stretch it, compress it. But everything grows from that one seed.You
You make it sound almost like architecture. Is there a spiritual dimension to all this structure for you?J. S. Bach
There is no division between the two. I write Soli Deo Gloria at the end of my scores because music, when properly ordered, reflects the divine order of creation itself. A fugue is a meditation on how unity emerges from diversity, how independent voices, each with their own character, can join to create something greater than any could achieve alone. This is not merely technique. When I compose a chorale for the congregation in Leipzig, I am shaping sound so that it carries the Word of God into the hearts of the faithful. Craft without devotion is hollow; devotion without craft is noise.Key ideas
- •Form arises from disciplined transformation of small ideas.
- •Counterpoint clarifies voices and unifies meaning.
- •Devotion and craft are mutually strengthening.
How to apply
- •Write daily inventions from short motives.
- •Use chorale harmonization to train harmony.
- •Plan long-range harmonic arcs before detail.
