The Polar Music Prize is a Swedish international award founded in 1989 by Stig Anderson, best known as the manager of the Swedish band ABBA, with a donation to the Royal Swedish Academy of Music.
 The award is annually given to one contemporary musician and one classical musician.
 Exceptions were made in 2001, when it was awarded to three musicians (one composer, one contemporary musician and one inventor), and 2003, when it was awarded only to one musician.
 Without any restrictions of nationality, the prize is to be "awarded for significant achievements in music and/or musical activity, or for achievements which are found to be of great potential importance for music or musical activity, and it shall be referable to all fields within or closely connected with music".
 The prize has been called the "Nobel Prize of Music" in Sweden.
The Wihuri Sibelius Prize is a music prize awarded by the Wihuri Foundation for International Prizes to prominent composers who have become internationally known and acknowledged.
 The Wihuri Sibelius Prize is one of the biggest and most prestigious music prizes in the world of classical music.
 The first Sibelius Prize was awarded to Finnish composer Jean Sibelius, whom the prize was named after, in 1953.
 By 2015, the Wihuri Foundation for International Prizes has awarded altogether 16 Wihuri Sibelius Prizes, the latest award climbing up to €150.000.
 The Wihuri Sibelius Prize winner is selected by a five-member committee that consists of experts from Finnish music institutions.
 The prize may be awarded to private individuals or organizations regardless of nationality, religion, race or language.
The Viola Concerto by William Walton was written in 1929 for the violist Lionel Tertis at the suggestion of Sir Thomas Beecham.
 The concerto carries the dedication "To Christabel" (Christabel McLaren, Lady Aberconway).
 But Tertis rejected the manuscript, and composer and violist Paul Hindemith gave the first performance.
 The work was greeted with enthusiasm.
 It brought Walton to the forefront of British classical music.
 In "The Manchester Guardian", Eric Blom wrote, "This young composer is a born genius" and said that it was tempting to call the concerto the best thing in recent music of any nationality.
 Tertis soon changed his mind and took the work up.

Hungarian Rhapsody No. 5, S.244/5, in E minor, is the fifth in a set of 19 Hungarian Rhapsodies by composer Franz Liszt.
 It is marked "Lento, con duolo".
 The piece was given the nickname "Héroïde-élégiaque" by the composer himself.
 It is very different from his other Hungarian Rhapsodies, as it does not follow the "intro" - "lassan" - "friska" structure and is perhaps the darkest and most melancholic of the set.
 It was later arranged for orchestra.
