Samuel Barber's Essay for Orchestra, Op. 12, completed in the first half of 1938, is an orchestral work in one movement. It was given its first performance by Arturo Toscanini with the NBC Symphony Orchestra on November 5, 1938 in New York in a radio broadcast concert in which the composer's Adagio for Strings saw its first performance. It lasts around 8 minutes and is dedicated "To C.E." The essay is now known as the First Essay for Orchestra after Barber wrote his Second Essay for Orchestra in 1942. He also wrote a Third Essay in 1978.
