Frédéric Chopin's Allegro de concert, Op. 46, is a piece for piano, published in November 1841.
 It is in one movement and takes between 11 and 15 minutes to play.
 The principal themes are bold and expressive.
 It has a curious place in the Chopin canon, and while its history is obscure, the evidence supports the view, shared by Robert Schumann and others, that it started out as the first movement of a projected third piano concerto, of which the orchestral parts are either now non-existent or were never scored at all.
 There is no evidence that Chopin ever even started work on the latter movements of this concerto.
She was born as Princess Caroline Murat in Paris and studied piano with Alfred Cortot and Samson François, Pierre Sancan, and later with Lev Oborin in Moscow.
 She was awarded her Licence de Concert when she was 14 years old from the Ecole Normale de Musique de Paris.
 Caroline started a lifelong career as teacher and performer aged 18 in Paris.
 She was the youngest laureat at the Marguerite Long international competition, won the Grand Prix at the Genève International Competition and the Terni Casagrande among other prestigious prizes.
 She cofounded with Martin Engstroem the Verbier Academy.
A piano piece or piece for piano (German: "Klavierstück" , ] ; French: "morceau [or] pièce pour (le) piano" , ] ) is a piece of music for piano.
 It is a generic name for any composition for the instrument, but when capitalised (Piano Piece, Piece for Piano) the name is used to indicate a (usually) single-movement composition for solo piano that has not been given a more specific name (such as Sonatina, "Allegro de concert" or "Le Bananier"), for example:
Three Concert Études ("Trois études de concert"), S.144, are a set of three piano études by Franz Liszt, composed between 1845–49 and published in Paris as "Trois caprices poétiques" with the three individual titles as they are known today.
Frédéric Chopin composed three piano sonatas, two being published in his lifetime, one posthumously.
 They are often considered to be among Chopin's hardest piano compositions both musically (along with his Polonaise-fantaisie, Op.
 61) and technically (along with his Allegro de concert, Op. 46).
 They cover a period of time from 1828 to 1844, reflecting Chopin's style changes.
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.
A concert piece (German: Konzertstück, also Concertstuck; French: pièce de concert, also morceau de concert) is a musical composition, in most cases in one movement, intended for performance in a concert.
 Usually it is written for one or more virtuoso instrumental soloists and orchestral or piano accompaniment.
Frédéric François Chopin ( ; ] ; born Fryderyk Franciszek Chopin, 1 March 181017 October 1849) was a Polish composer and virtuoso pianist of the Romantic era who wrote primarily for the solo piano.
 He gained and has maintained renown worldwide as a leading musician of his era, whose "poetic genius was based on a professional technique that was without equal in his generation."
 Chopin was born in what was then the Duchy of Warsaw and grew up in Warsaw, which in 1815 became part of Congress Poland.
 A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.

Albert Chamberland (12 October 1886 – 4 April 1975) was a Canadian violinist, composer, conductor, music producer, and music educator.
 As a violinist he was highly active as a chamber musician with a number of notable ensembles, including the Beethoven Trio with whom he made some early recordings for His Master's Voice during the first decade of the 20th century.
 For HMV he also made a few solo recordings and was active as a concert soloist as well.
 He was an orchestral performer with a variety of orchestras, notably serving as the Montreal Symphony Orchestra's first concertmaster.
 His compositional output was relatively small, consisting of an "Allegro militaire" for band, a "Sérénade" for violin and piano, an "Étude de concert d'après Rode", and a "Fantaisie" on the tune "Un Canadien errant".
 He notably performed the latter work at the Monument national on 13 April 1926.
