It is one of two profile choirs at Adolf Fredriks musikklasser i Stockholm (Adolf Fredrik's music classes in Stockholm), the other is Adolf Fredriks Flickkör. The boys 'choir was formed in 1965 by music director Jan-Åke Hillerud, who led the choir until 1997. The boys' choir's activities were down until 2001, when the choir started again under the direction of Christoffer Holgersson. From the autumn of 2009-spring 2017, the choir was led by Pelle Olofson and during these years the choir was a pure treble choir with only soprano and alto parts. The current conductor and artistic director is Tony Margeta.

The choir today consists of about 60 boys and young men in grades 5-9 and is divided into soprano, alto, tenor and bass.
