This is a flash-mob classical rendition of Ode to Joy (Beethoven Symphony No.9), incredibly well performed.
The Symphony No. 9 in D minor, Op. 125, is a choral symphony, the final complete symphony by Ludwig van Beethoven, composed between 1822 and 1824. It was first performed in Vienna on 7 May 1824. The symphony is regarded by many critics and musicologists as Beethoven’s greatest work and one of the supreme achievements in the history of music.[1][2] One of the best-known works in common practice music,[1] it stands as one of the most frequently performed symphonies in the world.[3][4]
The Ninth was the first example of a major composer using voices in a symphony.[5] The final (4th) movement of the symphony features four vocal soloists and a chorus. The text was adapted from the “Ode to Joy“, a poem written by Friedrich Schiller in 1785 and revised in 1803, with additional text written by Beethoven. (source: wikipedia)
