Between 1640 and 1720 the immigrant German Düben family produced three generations of Capellmeisters at Sweden’s wealthy and fashionable Royal Court, where they amassed a huge collection of printed music and manuscripts. The meticulous cataloguing of this collection at Uppsala University has allowed Spiritato’s Kinga Ujszászi to fulfil the ensemble's avowed aim of exploring a vast and little-known repertory.

Of particular interest to the group was music that appears to show the first collaborations of the royal Capelle with the separate trumpet corps, bringing trumpets into the context of courtly music and allowing the players to push the boundaries of their instruments and skills.
