Symphony No. 1 (Mozart) in the finale of his "Jupiter" symphony, No. 41. The four notes, Do, Re, Fa, Mi, make an appearance in several of Mozart's works, including his Symphony No. 33. This theme is stated by the horns in his first symphony. In his book on the Piano Concertos, Cuthbert Girdlestone pointed out the similarity between the opening of this symphony and that of Mozart’s Piano Concerto No. 22 K482, composed some twenty years later. Symphony No. 1 (Mozart) The Symphony No. 1 in E major, K. 16, was written in 1764 by Wolfgang Amadeus Mozart at the age of eight years.
Symphony No. 2 (Rachmaninoff) Rachmaninoff wrote not only his Second Symphony, but also the tone poem "Isle of the Dead". Rachmaninoff was not altogether convinced that he was a gifted symphonist.

He was very unhappy with the first draft of his Second Symphony
