Johann Sebastian Bach (1685-1750) stands as one of music history's most prolific and technically sophisticated composers. His vast output spans sacred and secular works across nearly every Baroque genre, from the Well-Tempered Clavier to the Brandenburg Concertos, all written during his roles as court musician, cantor, and church composer across Germany. For piano students, Bach's music offers an unmatched education in counterpoint, voice leading, and structural clarity; his compositions train the ear and hands in ways few other composers can match.
