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 (Borodin) himself, and is considered to be one of his greatest. It has many melodic resemblances to both "Prince Igor" and "Mlada", which were two theatrical works that diverted Borodin's attention away from the B minor symphony between 1869–75. According to the account of Borodin's friend Nikolay Kashkin, the symphony's striking and abrupt opening theme originated from the abandoned chorus of Polovtsians, and the Soviet biographer Serge Dianin notes that there is a common thread present in all three pieces. According to Dianin, "it is for this reason that we find certain similarities in the themes Borodin uses in these works."
