(bStockholm, 19 Dec 1879; d Stockholm, 1 Sept 1964). Swedish organist and composer. At the Swedish Royal Academy of Music he studied organ with Lagergren (examination 1896) and theory and composition with Dente (examination 1899). Subsequently he joined the conservatory staff, teaching harmony (1908–24) and organ (1924–45, from 1926 as professor). He also held the post of organist at the Gustav Vasa church in Stockholm. One of the great organ virtuosos of his time, he had a particular reputation for French music, in which he continued the tradition of Emil Sjögren. His teaching influenced several generations of Swedish church musicians, and he helped to develop church music in Sweden, after a long period of decline, as a member of official committees set up to supervise the liturgy and hymnology.
In his compositions Olsson was strongly influenced by French organ music, but he had a sure feeling for counterpoint and so was able to give a firm foundation to his late Romantic style. A growing interest in earlier music is displayed in the six Gregorianska melodier op.30 (1910), in which the plainchant themes are treated with a well-balanced interplay of spare counterpoint and melodic-harmonic fullness. The Sex latinska hymner op.40 for chorus (1919) also show a firm combination of polyphony with conventional harmonic progressions, though Olsson’s use of polytonality brings them to a stage of technical advance not found in other Swedish choral works of the period (nor in any other compositions of his). His largest and best-known work is the Te Deum op.25 for chorus, string orchestra, harp and organ (1906), a masterpiece of Swedish church music.
Apart from this, Olsson’s best pieces are for the organ, the earliest of them being the Suite in G op.20. The Fantasy and Fugue op.29, a composition in Phrygian E on the chorale Vi lofva dig, o store Gud, introduced a new style into Swedish organ music, notably in its polyphonic treatment of an old church hymn. The development initiated by this work culminated in the Credo symphoniacum op.50, a three-movement symphony on Gregorian themes written for the ecumenical meeting at Uppsala in 1925. Other pieces, such as the great Sonata in E op.38 and the three preludes and fugues, show Olsson retaining late Romantic traditions. His remaining works include a fine quartet (op.10) and other instrumental pieces; some of his folksong arrangements and original pieces for male chorus have remained in the repertory.

(b Budapest, 2 April 1931). Hungarian ethnomusicologist and composer. He studied at the Liszt Academy of Music under Kodály, Szabolcsi, Lajos Bárdos and Endre Szervánszky, taking diplomas in musicology (1956) and composition (1958). In 1958 he became a research fellow of the Folk Music Research Group (later a department of the Institute of Musicology of the Hungarian Academy of Sciences) and worked with Pál Járdányi on the systematization of Hungarian strophic folksongs (1958–66), developing a strictly musical method based on tune types. On the basis of this system he edited the sixth and seventh volumes of the Corpus Musicae Popularis Hungaricae. In 1966 he spent nine months in Egypt, studying Egyptian folk and art music. His research has centred on the development of variants of basic melodic patterns in Hungarian folk music, particularly in that of the Trans-Danubian area. His intensive fieldwork (1947–65) resulted in the transcription of about 8000 tunes from 150 villages in Hungary and Hungarian-speaking areas of Slovakia and Yugoslavia. His compositions include a Rondo for violin and piano (1954), a Piano Sonata (1956), some choruses, and arrangements of folksongs, mostly with folkdance choreography.
