  the royal scottish national orchestra (rsno) is scotland's national symphony orchestra. based in glasgow, the 89-member professional orchestra also regularly performs in edinburgh, aberdeen and dundee, and abroad. formed in 1843 to accompany the glasgow choral union (today known as the rsno chorus) and recognised formally in 1891 as the scottish orchestra, the company has performed full-time since 1950, when it took the name scottish national orchestra. it was awarded royal patronage in 1991. shortly after the award it briefly used the title royal scottish orchestra before reverting to its present name. under its first scottish-born, and longest serving conductor, sir alexander gibson, the orchestra began to develop an international profile. in line with gibson's own specialities, the orchestra became known for its interpretations of scandinavian composers, notably jean sibelius and carl nielsen. this was consolidated in the tenure of neeme jÃ¤rvi, who also led the orchestra through its first complete gustav mahler cycle. the second scot to lead the orchestra, bryden thomson, maintained the nordic link with a cycle of nielsen symphonies. the rsno's base is at henry wood hall in glasgow and is also used as its recording venue; a new base is being constructed within the royal concert hall, buchanan street. the rsno also performs throughout scotland, at such venues as the glasgow royal concert hall, usher hall (edinburgh), caird hall (dundee), aberdeen music hall, perth concert hall and eden court inverness. the orchestra had a long-standing recording contract with chandos records in the 1980s and 1990s which has recently been re-established. today, it chiefly records for naxos records, most notably in a cycle of anton bruckner symphonies with the late georg tintner, cycles of arnold bax symphonies with david lloyd-jones, and several recordings of american works (including the complete orchestral works of samuel barber) conducted by marin alsop, who was the rsno's principal guest conductor from 2000 to 2003. in may 2007, the rsno made their first recordings with stÃ©phane denÃ¨ve, of music of albert roussel, for naxos. the first recording{{cite news | url=http://www.guardian.co.uk/music/2007/jun/08/
