Schola Cantorum has from the very start played an important role in the Icelandic music scene with a repertoire that consists mainly of Renaissance, baroque and contemporary music, including numerous première performances of works by Icelandic composers. Schola Cantorum has given concerts in Norway, Sweden, Finland, Italy, Spain, Germany, Switzerland, France, Japan and the United States. In 2017, Schola Cantorum was invited by the Los Angeles Philharmonic to perform four concerts at the Walt Disney Concert Hall at the Reykjavík Festival in Los Angeles.
Upcoming concerts are scheduled at the Oslo International Church Music Festival, the KLANG Festival in Copenhagen and in France. Schola Cantorum can be heard on many recordings, among which are the complete choral and orchestral works of Icelandic composer Jón Leifs, issued by Swedish label BIS.
The choir has worked with artists such as Björk, Sigur Rós, Jóhann Jóhannsson and Swedish experimental band Wildbirds & Peacedrums. Schola Cantorum has been active within many genres; for instance, the choir performed on the soundtrack of the action-adventure video game God of War, released by Sony in 2018 and 2021. Two new albums featuring the choir will be released by BIS in 2022 and 2023. In 2007, the choir was nominated for the Nordic Council Music Prize.
In 2009, it was named the Official Musical Ensemble of the City of Reykjavík. In March 2017, Schola Cantorum received the Icelandic Music Awards as the Performer of the Year. Schola Cantorum is supported by the City of Reykjavík and the Icelandic Ministry of Culture.
