List of compositions by Sergei Rachmaninoff: The compositions of Sergei Rachmaninoff (1873–1943) cover a variety of musical forms and genres.  Born in Russia, he studied at the Moscow Conservatory with Nikolai Zverev and Anton Arensky, and while there, composed some of his most famous works, including the first piano concerto (Op. 1) and the Prelude in C-sharp minor (Op. 3, No. 2).  Although spread over three different opuses, he did go on to complete an important set of 24 preludes in all the major and minor keys.  His Symphony No. 1 (Op. 13) was one of his first compositions as a "Free Artist" after graduation, and subsequently his first critical failure.  The derision he received sent him into depression.  After being sent through autosuggestive therapy, he composed his second piano concerto (Op. 18), which is still part of the major orchestra repertoire today.  In 1909, he made his first tour of the United States, and composed Piano Concerto No. 3 (Op. 30), notable for its difficult cadenza.  After this, due to migration from Russia in 1917 and his busy concert career, his output as a composer decreased, and during this period, he completed only six compositions.  His last work, "Symphonic Dances" (Op. 45), was completed in 1940.

Piano Concerto No. 3 (Saint-Saëns): The Piano Concerto No. 3 in E flat major, Op.  29 by Camille Saint-Saëns, was composed in 1869.  The concerto is written in 3 movements.  When the concerto was first performed by Saint-Saëns himself at the Leipzig Gewandhaus in 1869 it was not well received, possibly because of its harmonic experimentation.  Saint-Saëns's third concerto is not as often performed as his famous second concerto, or the fourth or fifth concertos, but it is still an important addition to the piano concerto repertoire.  It was dedicated to Élie-Miriam Delaborde, a pianist who is believed to have been the natural son of Charles-Valentin Alkan.

Piano Concerto No. 10 (Mozart): It is not known when Mozart completed his concerto for two pianos in E-flat major, K.  365/316a, but research by Alan Tyson shows that cadenzas for the first and third movements are written in his and his father's handwriting on a type of paper used between August 1775 and January 1777 .  However, most sources, including Alan Tyson's book "Mozart: Studies of the Autograph Scores" (1987) or more recent Lindeman's "The Concerto: A Research and Information Guide" (2006) indicate that it was composed in 1779.  This date was retained on Wikipedia pages for K.365/316a in any other language.  It is presumed that Mozart wrote it to play with his sister Maria Anna (“Nannerl”).  Years later he performed it in a private concert with pupil Josepha Barbara von Auernhammer.

Piano Concerto (Dvořák): The Concerto for Piano and Orchestra in G minor, Op. 33, is the only piano concerto by Czech composer Antonín Dvořák.  Written in 1876, it was the first of three concertos that Dvořák completed, followed by the Violin Concerto, Op. 53 from 1879 and the Cello Concerto, Op. 104, written in 1894–1895.  The piano concerto is probably the least known and least performed of Dvořák's concertos.

Rondo for piano and orchestra (Beethoven): Ludwig van Beethoven's Rondo for piano and orchestra in B-flat major, WoO, 6 was composed in 1793 and originally intended as the final movement for his second piano concerto.  Hans-Werner Küthen states this was probably the finale for the first and second versions of the second piano concerto, being replaced by the final version of the rondo in 1795.  He also notes that the most likely inspiration for the insertion of an andante section into the rondo is the concluding rondo of Mozart's twenty-second piano concerto.

Piano Concerto No. 24 (Mozart): The Piano Concerto No. 24 in C minor, K.  491, is a concerto composed by Wolfgang Amadeus Mozart for keyboard (usually a piano or fortepiano) and orchestra.  Mozart composed the concerto in the winter of 1785–1786, finishing it on 24 March 1786, three weeks after the completion of the Piano Concerto in A major.  As Mozart intended to perform the work himself, the soloist's part was not fully written down.  The premiere was in early April 1786 at the Burgtheater in Vienna.  Chronologically the work is the twentieth of Mozart's 23 original piano concertos.

Yellow River Piano Concerto: The Yellow River Piano Concerto () is a piano concerto arranged by a collaboration between musicians including Yin Chengzong and Chu Wanghua, and based on the "Yellow River Cantata" by composer Xian Xinghai.  Since its politicised premiere in 1969 during the Cultural Revolution, the Concerto has become popular in China and amongst overseas Chinese nationalists.  It is noted for a difficult solo part.  This piano concerto and the Butterfly Lovers' Violin Concerto, which tells the story of the Butterfly Lovers, are two internationally known Chinese works that combine Western music methodology with Chinese source materials.

Piano Concerto No. 3 (Tchaikovsky): Pyotr Ilyich Tchaikovsky's Piano Concerto No. 3 in E-flat major, Op.  posth.  75, was originally begun as a symphony in E-flat.  The composer ultimately abandoned this symphony, but, in 1893, started to rework it into a piano concerto, before abandoning all but the first movement, which he completed as a concert piece for piano and orchestra.  It was published posthumously, in 1894, as a single-movement "Allegro Brillante".  The Symphony No. 6 "Pathétique" was the last of Tchaikovsky's compositions to be performed in his lifetime, but the "Allegro Brillante", now known as the Piano Concerto No. 3, was his last completed composition.

Piano Concerto No. 2 (Chopin): The Piano Concerto No. 2 in F minor, Op.  21, is a piano concerto composed by Frédéric Chopin in 1829.  Chopin wrote the piece before he had finished his formal education, at around 20 years of age.  It was first performed on 17 March 1830, in Warsaw, Poland, with the composer as soloist.  It was the second of his piano concertos to be published (after the Piano Concerto No. 1), and so was designated as "No. 2", even though it was written first.

Maria Anna Mozart: Maria Anna Walburga Ignatia Mozart (30 July 1751 – 29 October 1829), called Marianne and nicknamed "Nannerl", was a musician, the older sister of Wolfgang Amadeus Mozart and daughter of Leopold and Anna Maria Mozart.
