Title: Symphony No. 3 (Wirén)
Content:  The Symphony No. 3, Op. 20, is a three-movement orchestral composition by the Swedish composer Dag Wirén, who wrote the piece from 1943–44. Despite its numbering, the Third Symphony represents Wirén's second contribution to the form as a professional (the composer withdrew the Symphony No. 1, Op. 3—a 1932 experimental "study work" from his student years in Paris—and prohibited its performance), arriving five years after its predecessor, the Symphony No. 2. Swedish conductor Sixten Eckerberg premiered the new symphony with the Gothenburg Symphony Orchestra in Gothenburg on 28 September 1944.

Title: Symphony No. 3 (Rachmaninoff)
Content:  Sergei Rachmaninoff composed his Symphony No. 3 in A minor, Op. 44 between 1935 and 1936. The Third Symphony is considered a transitional work in Rachmaninoff's output. In melodic outline and rhythm it is his most expressively Russian symphony, particularly in the dance rhythms of the finale. What was groundbreaking in this symphony was its greater economy of utterance compared to its two predecessors. This sparer style, first apparent in the Rhapsody on a Theme of Paganini, enhances the emotional power of the work. The symphony was premiered on November 6, 1936, with Leopold Stokowski conducting the Philadelphia Orchestra. Critical opinion was divided and public opinion negative toward the work. Rachmaninoff remained convinced of the piece's worth, however, and conducted the Philadelphia Orchestra in the first recording of the work in 1939. Following the reevaluation of Rachmaninoff's work in the 1970s, the symphony has been viewed in a more favorable light and has been frequently played and recorded.

Title: Symphony No. 3 (Rautavaara)
Content:  Finnish composer Einojuhani Rautavaara wrote his Symphony No. 3 in 1959-60. Although employing serial procedures, the harmonies are firmly tonal throughout. In fact, the romantic gestures of the symphony, the majestic use of brass (including Wagner Tubas), as well as the use of German tempo markings, owes much to the symphonies of Anton Bruckner, and the symphony has been termed by critics as neo-Brucknerian in style.
Title: Symphony No. 3 (Glazunov)
Content:  Alexander Glazunov composed his Symphony No. 3 in D major, Op. 33, in 1890, and it was published by 1892 by the Leipzig firm owned by Mitrofan Belyayev. The symphony is dedicated to Pyotr Ilyich Tchaikovsky and was first performed in St. Petersburg in December 1890 under the baton of Anatoly Lyadov. The symphony is considered a transitional work, with Glazunov largely eschewing the influences of Balakirev, Borodin, and Rimsky-Korsakov inherent in his earlier symphonies for the newer influences of Tchaikovsky and Wagner. Because of this change, the Third has been called the "anti-kuchkist" symphony in Glazunov's output (kuchkist from kuchka, the shortened Russian name for the nationalist music group The Five). He would tone down these new influences in his subsequent symphonies as he strove for an eclectic mature style. The Third also shows a greater depth of expression, most evident in the chromatic turns of its third movement, reminiscent of Wagner's opera Tristan und Isolde.
