Overview

Johann Sebastian Bach is widely regarded as one of the greatest composers in the history of Western classical music. Born in Eisenach, Germany, on March 21, 1685, he came from a long line of musicians and quickly developed exceptional skill in composition and performance.

Bach's work combined technical mastery, emotional depth, and profound religious devotion. Though underappreciated during his lifetime, his music experienced a revival in the 19th century, cementing his legacy as a central figure in Baroque music.

Over 1,000 works are attributed to Bach, including cantatas, concertos, and organ pieces, with more than 200 sacred cantatas still performed today.
He served as Thomaskantor in Leipzig from 1723, directing music at St. Thomas Church and teaching at the associated school.
Bach was a master of counterpoint, a compositional technique involving interweaving independent melodies, which he perfected in works like The Art of Fugue.
Despite his fame today, Bach was primarily known as an organist during his life, not a composer, and many of his works were unpublished.
He fathered 20 children with two wives, and several of his sons, including C.P.E. and J.C. Bach, became influential composers in their own right.

How It Works

Bach’s music is studied for its structural precision, harmonic richness, and emotional resonance. Each composition demonstrates meticulous craftsmanship, often built on mathematical patterns and deep religious symbolism.

Fugue: A fugue is a complex polyphonic composition where a main theme (the subject) is introduced and then imitated in different voices, creating layered textures. Bach’s Well-Tempered Clavier contains 48 preludes and fugues demonstrating this form.
Counterpoint: This technique involves combining multiple independent melodies; Bach’s mastery is evident in works like The Art of Fugue, composed entirely in strict counterpoint.
Well-Tempered Tuning: Bach championed tuning systems allowing music in all 24 keys; his Well-Tempered Clavier (1722, 1742) showcased this innovation.
Chorale Harmony: He harmonized hundreds of Lutheran hymns, setting each with rich four-part textures that remain models for music students today.
Ornamentation: Bach used intricate trills, mordents, and turns, especially in keyboard works, to enhance expressiveness and technical brilliance.
Stile Antico: In the Mass in B minor, Bach employed the ancient church style, blending Renaissance polyphony with Baroque instrumentation for dramatic effect.
