DIAMM Publications

There are copies of most older DIAMM publications available at a significant discount as they are very slightly damaged (usually just very slightly bumped) from a warehouse move. These copies are shown on our shop page as ‘seconds’ separately from the main product listing.

The Anne Boleyn Music Book

Our latest facsimile publication, but already out of print. Copies are still available from the library of the Royal College of Music though.

The Ferrell-Vogüé Machaut MS

The most hidden of all the Machaut manuscripts is now the most available. Winner of the American Musical Society 2015 Claude V. Palisca Prize for the most outstanding scholarly edition or translation in the field of musicology published in 2014.
