In 1985 the CPO's regular performing venue became Jack Singer Concert Hall in the Calgary Centre for the Performing Arts (now EPCOR Centre for the Performing Arts).
An amalgamation (1955) of the Calgary Symphony Orchestra and the Alberta Philharmonic, the latter established earlier in 1955 under the Dutch conductor Henry Plukker (b Dornbirn, Austria, 14 May 1908). Plukker served as the CPO's conductor until 1962. Initially the CPO presented 10 concerts annually at the Palace Theatre and some school programs. Later the orchestra played in the Alberta Jubilee Auditorium. By 1963, when Haymo Taeuber became conductor, attendance had grown from an average of 900 per concert to over 2500. Under Taeuber (b Graz, Austria, 1 Jan 1908; a pupil of Felix Weingartner and a former conductor of the Vienna Boys Choir and of orchestras in Austria, Turkey, and Iran), junior, intermediate, and senior youth orchestras were established to encourage and train young musicians. Taeuber was succeeded in 1968 for one year by the noted pianist José Iturbi (b Valencia 28 Nov 1895, d Hollywood 28 Jun 1980), during whose term the orchestra for the first time augmented its ranks with 27 full-time musicians (increasing that number to 45 by the 1977-8 season). After Iturbi and a year of guest conductors, Maurice Handford (b Salisbury, Wiltshire, England, 29 Apr 1929, d there 16 Dec 1986) led the orchestra 1970-75, followed again by guest conductors; Franz-Paul Decker was artistic adviser and principal guest conductor 1975-7. Arpad Joo (b Budapest 1948, a protégé of Kodály) was music director 1977-84, succeeded by Mario Bernardi. By the 1990-1 season the orchestra had 63 full-time players and a season of 42 weeks, including lecture concerts; chamber music concerts; a pop series led by principal pop conductor Richard Hayman, Susan Haig (staff conductor 1988-91, succeeded in 1991 by André Jutras), and guest conductors; a 'Young People's Series'; '20th Century Classics' (begun in the 1986-7 season); as well as company-sponsored, community, and school concerts. The orchestra has also accompanied Calgary Opera productions. The Calgary Philharmonic Chorus was formed in 1963 by Haymo Taeuber who conducted the 70-voice choir until his departure in 1968, when it was disbanded. Lloyd Erickson conducted a revived chorus, active 1970-5; after another hiatus 1975-7 the choir was again revived under Erickson's direction. Terence Fullerton became chorusmaster in 1979. In 1988 the choir comprised 125 singers. The orchestra has also collaborated with the Vancouver Bach Choir and the CBC Vancouver Orchestra.
Bernardi is credited with raising the orchestra's artistic standards and with promoting its recognition as an artistically mature orchestra of national importance; under his direction it has broadcast extensively on CBC radio and has made its first recordings. In May 1989 it toured to Thunder Bay, Ottawa, Joliette, St Catharine's, Hamilton, Toronto, and Kitchener.
