Since my study years, I have participated in concerts held at 

Kloster Wienhausen. In these events, the Wienhausen Songbook was always accompanied by fitting music. 

In 2006, I finally approached the archivist of the Lüneburg monasteries to inquire about additional music manuscripts. 

However, it had never been investigated whether similar materials were preserved in the six so-called Heath monasteries 

(Ebstorf, Isenhagen, Lüne, Medingen, Walsrode, Wienhausen).


A preliminary examination revealed that numerous musical works were preserved as waste (bindings), as well as in agendas, etc. 

With the assistance of the Klosterkammer Hannover and 

other supporters, I initiated an extensive project. 

It included:

•    Examination of all existing music manuscripts, including those particularly valuable and informative Medingen manuscripts distributed around the world, in collaboration with a specialized musicologist.

•    Systematic creation of a list of all incipits (chants) and their publication in book form and as a database.

•    Publication of all musical representations in book form.

•    Establishment of the ensemble devotio moderna.

•    Reconstruction of instruments based on Medingen depictions.

•    Recording selected chants on 6 CDs.

•    Publication of recorded chants in practical editions.

•    Conducting concerts on-site and elsewhere 

(e.g., Cage Festival Halberstadt).

•    Presentations at conferences and similar events.

•    Practical workshops with concluding concerts in the monasteries and elsewhere.

These activities received significant resonance, 

leading the curator of Kloster Ribnitz in Mecklenburg-Vorpommern 

to draw my attention to their holdings, and the 

St. Marien Barth Church Library pointed to their resources. 

The work in the Heath monasteries found a wonderful and intensive continuation in the commitment to the preservation and restoration 

of the Barth Library.

Content parallels between all these North German monasteries became apparent, prompting further recordings and sheet music editions. 

I also examined the holdings of the Geistliches Ministerium in Greifswald and practically perform much of the rediscovered treasures,

 bringing them back to life. 

This is done whenever possible in collaboration with local activists. 

For example, an early Resurrection story from the time before Schütz was first performed again in Greifswald Cathedral for Easter 2016. 

In 2023, we have recorded parts of the Ribnitz Requiem manuscript.
