The institute provides music education for many age groups, including infants and children, school-aged adolescents, and undergraduate and postgraduate students.

[1] The institute's motto is "From music kindergarten to concert podium," which sums up the philosophy that constitutes the foundation on which their education system is built.

This education model has enabled Barratt Due to establish itself as an important institution and contribute largely to the Norwegian classical music industry at least for the past three generations.

Stephan Barratt-Due is the Barratt Due's artistic director, and leads the institute's ensemble-in-residence, Oslo Camerata.

Both musicians were well-established and acknowledged during their time, and the family moved into Lyder Sagens gate 2 on 26 October 1931, where the institute is located today.
