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. 3 (Glazunov) when Glazunov shared his reminiscences of Tchaikovsky, he said, "He also knew my "Third Symphony", which is dedicated to him. Much in it found his approval and, at his request, I often played the scherzo of the symphony to him on the piano. When I asked him what he would regard as the most significant weakness in my works, he said: 'Some longevities and the lack of pauses.' Later, when Pyotr Ilyich had long departed this world, I always remembered his words, and in my subsequent production I always took pains to pay heed to them." Symphony No. 3 (Glazunov)
