Adagio da 7ª Sinfonia de Bruckner

«Symphony No. 7 in E major was the most beloved of Bruckner's symphonies with audiences of the time, and is still popular. It was written 1881-1883 and revised in 1885. During the time that Bruckner began work on this Symphony, he was aware that Wagner's death was imminent, and so the Adagio is slow mournful music for Wagner, and for the first time in Bruckner's oeuvre, the Wagner tuba is included in the orchestra.»
