Norway constitutional monarchy in Northern Europe

Norway, officially the Kingdom of Norway, is a Nordic country in Northwestern Europe whose territory comprises the western and northernmost portion of the Scandinavian Peninsula; the remote island of Jan Mayen and the archipelago of Svalbard are also part of the Kingdom of Norway. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land.

Pianist musician who plays the piano

A pianist is an individual musician who plays the piano. Since most forms of Western music can make use of the piano, pianists have a wide repertoire and a wide variety of styles to choose from, among them traditional classical music, jazz, blues, and all sorts of popular music, including rock and roll. Most pianists can, to an extent, easily play other keyboard-related instruments such as the synthesizer, harpsichord, celesta, and the organ.

Composer person who creates music, either by musical notation or oral tradition

A composer is a musician who is an author of music in any form, including vocal music, instrumental music, electronic music, and music which combines multiple forms. A composer may create music in any music genre, including, for example, classical music, musical theatre, blues, folk music, jazz, and popular music. Composers often express their works in a written musical score using musical notation.



Thomas Tellefsen, the youngest of six siblings, [1] was born in Trondheim, Norway, where he studied with his father, the organist Johan Christian Tellefsen (17741857), and with Ole Andreas Lindeman. [2] Thomas gave his first public concert in his home town in the spring of 1842. Shortly after, he went to Paris, where he became the pupil of his compatriot Charlotte Thygeson, and later attended some of Friedrich Kalkbrenner's classes. During the years 1844 to 1847, he was taught periodically by Frédéric Chopin, who also became his personal friend and had considerable influence on his musical taste, style of playing, and compositions.

Trondheim City in Norway

Trondheim is a city and municipality in Trøndelag county, Norway. It has a population of 193,501, and is the third-most populous municipality in Norway, although the fourth largest urban area. Trondheim lies on the south shore of Trondheim Fjord at the mouth of the River Nidelva. The city is dominated by the Norwegian University of Science and Technology (NTNU), the Foundation for Scientific and Industrial Research (SINTEF), St. Olavs University Hospital and other technology-oriented institutions.

Organist musician who plays any type of organ

An organist is a musician who plays any type of organ. An organist may play solo organ works, play with an ensemble or orchestra, or accompany one or more singers or instrumental soloists. In addition, an organist may accompany congregational hymn-singing and play liturgical music.

Paris Capital of France

Paris is the capital and most populous city of France, with an area of 105 square kilometres and an official estimated population of 2,140,526 residents as of 1 January 2019. Since the 17th century, Paris has been one of Europe's major centres of finance, commerce, fashion, science, and the arts.

Duchess Marcelina Czartoryska took him to the Hôtel Lambert in Paris, where he made his debut as a pianist with great success on 29 April 1851. [3] Soon after that, Tellefsen became regarded as one of the outstanding pianists of his time, and was especially admired as an interpreter of Chopin's music. When Chopin died in 1849, Tellefsen took over some of his teacher's pupils, including Jane Stirling. [3] In the 1850s and 1860s, Tellefsen was regarded as a very successful pianist, and he toured several times in England, Sweden, and Norway. He died in Paris, and is buried at the Cimetière d´Auteuil.

Hôtel Lambert hôtel particulier

The Hôtel Lambert is a hôtel particulier, a grand mansion townhouse, on the Quai Anjou on the eastern tip of the Île Saint-Louis, in 4th arrondissement of Paris. In the 19th century, the name Hôtel Lambert also came to designate a political faction of Polish exiles associated with Prince Adam Jerzy Czartoryski, who had purchased the Hôtel Lambert.

Jane Stirling Scottish amateur pianist

Jean ("Jane") Wilhelmina Stirling was a Scottish amateur pianist who is best known as a student and later friend of Frédéric Chopin whose two nocturnes are dedicated to her. She took him on a tour of England and Scotland in 1848, and took charge of the disposal of his effects and manuscripts after his death in 1849. While there is no evidence they were lovers, she was often referred to, after Chopin's death, as "Chopin's widow".

England Country in north-west Europe, part of the United Kingdom

England is a country that is part of the United Kingdom. It shares land borders with Wales to the west and Scotland to the north-northwest. The Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight.


Among his published works, Tellefsen wrote sixteen mazurkas, five chamber music works (two sonatas for violin and piano, a sonata for cello and piano, a sonata for two pianos, and a trio for piano, violin and cello), composed between 1854 and 1867. He also wrote two piano concertos, the first in 1848 and the second in 1853, six waltzes, four nocturnes, three études, and a number of larger works and salon pieces, which were written for the teaching of his pupils. This list is sortable by title, key, tempo markings, genre, and year of composition, but non-sortable by opus number and notes.

Works without opus number

Tellefsen's works without opus number are either piano studies or liturgical pieces. His Moderato, written in 1842, is one of his first attempts in composition. Another collection of works consists of twenty-one short fughettas, versetti and cantabile pieces, suitable in length in Roman Catholic and Lutheran services during the time they were written. The versetti are organ verses played in alternation with sung verses of hymns. The preludes were played for organ or piano with pedal. They were used as preludes and postludes, while a cantabile piece might also appear after the sermon as an introduction to the next hymn. Variations on hymn tunes are a much-used form in church services as well. This list is sortable by title, key, tempo markings, genre and year of composition, and non-sortable by number and notes.

Miscellaneous solo piano compositions (Rachmaninoff) group of piano pieces by Sergei Rachmaninoff that were either lost, unpublished, or not assigned an opus number

The composer Sergei Rachmaninoff produced a number of solo piano pieces that were either lost, unpublished, or not assigned an opus number. While often disregarded in the concert repertoire, they are nevertheless part of his oeuvre. He composed sixteen such pieces, and all others are lost. Ten of these pieces were composed before he completed his Piano Concerto No. 1, his first opus, and the rest interspersed throughout his later life. In these casual works, he draws upon the influence of other composers, including Frédéric Chopin and Pyotr Tchaikovsky. The more substantial works, the Three Nocturnes and Four Pieces, are sets of well-thought out pieces that are his first attempts at cohesive structure among multiple pieces. Oriental Sketch and Prelude in D minor, two pieces he composed very late in his life, are short works that exemplify his style as a mature composer. Whether completed as a child or adult, these pieces cover a wide spectrum of forms while maintaining his characteristic Russian style.

Doctor of Musical Arts doctoral academic degree in music

The Doctor of Musical Arts (D.M.A.) is a doctoral academic degree in music. The D.M.A. combines advanced studies in an applied area of specialization with graduate-level academic study in subjects such as music history, music theory, or music pedagogy. The D.M.A. degree usually takes about three to four years of full-time study to complete, preparing students to be professional performers, conductors, and composers. As a terminal degree, the D.M.A. qualifies its recipient to work in university, college, and conservatory teaching/research positions. Students seeking doctoral training in musicology or music theory typically enter a Ph.D. program, rather than a D.M.A. program.
