Johann Sebastian Bach (1685-1750) was a master of counterpoint and harmonic language whose works remain central to music education and performance across all levels. His compositions span sacred and secular genres, and his harmonic innovations continue to influence how musicians understand voice leading, chord progression, and musical architecture. Charles Gounod (1818-1893), a French composer and conductor, created this famous arrangement by adding his own melodic line over Bach's Prelude in C Major from the Well-Tempered Clavier, transforming it into one of the most recognizable religious songs in Western music.
