The majority of Romantic composer Robert Schumann's works are written for, or prominently featuring, the piano. This specific piece is for piano and flute. The composer does an extraordinary job in the interactions between the two instruments, as they both seem to act with one mind throughout. The melodic lines are offered up by one instrument and subsequently commented on by the other, with the two voices echoing each other to great effect throughout the work. Schumann's Sonata In A Minor is a spectacular display from one of the most famous composers of the 19th Century, so be sure to check it out.
