Given that the reformed liturgy typically does not allow for independent instrumental music, the complete arrangements of the Geneva Psalter, edited here according to the sources by the Basel teacher and organist Samuel Mareschal (1554-1640), are noteworthy. Furthermore, the pieces, with their improvisational style, provide rare insights into the practice of music-making and instrumental pedagogy in the context of universities and schools. Last but not least, Mareschal's tablatures also serve as testimonies of private piety in the post-Reformation period in Basel and Moravia. This volume contains an edition of the three autograph tablature manuscripts, supplemented by a brief historical overview, source descriptions, notes on notation and transcription, as well as a list of readings with additional information about the writing process.
