Sonate "Undine" for flute and piano, Op. 167

Carl Reinecke (1824-1910) was a towering figure in 19th-century German music, serving as a composer, conductor, virtuoso pianist, and one of the most influential pedagogues in history. He is best remembered today as the primary guardian of the Classical-Romantic tradition during the rise of modernism.
Born in Altona, then part of the Duchy of Holstein (under Danish rule, now part of Germany), he initially studied with his father, Johann Peter Rudolph Reinecke, a respected music theorist and teacher. Unlike many of his peers, Carl never attended a formal conservatory; his father’s rigorous curriculum focused on the works of Bach, Mozart, and Beethoven.
He began composing at age seven and made his public debut as a pianist at age eleven. In 1843, a concert tour led him to Leipzig, where he met Felix Mendelssohn and Robert Schumann, both of whom became his mentors and profound stylistic influences.
In 1860, Reinecke was appointed the conductor of the Leipzig Gewandhaus Orchestra, a position he held for 35 years. Under his leadership, the orchestra became a bastion of traditionalism, famously premiering Brahms’s A German Requiem.
As a professor at the Leipzig Conservatory, he taught many of the future masters, including Edvard Grieg, Isaac Albéniz, Leoš Janáček, Max Bruch, and Arthur Sullivan.
His music is characterized by its elegance, clarity of form, and "Mendelssohnian" lyricism. While he lived to see the dawn of the 20th century, he remained a staunch conservative, rejecting the "New German School" of Liszt and Wagner.
