Interlude Music Productions… an unusual publishing house of unique sheet music


Saving forgotten, but valuable music from oblivion; that is the prime objective of Interlude Music Productions.

Since the 1970’s, publisher Willem Poot has scoured the Dutch and European libraries for forgotten pieces from both well-known and obscure composers. In addition, he arranges compositions for unusual combinations of instruments. A good example being his arrangement of Mozart’s Gran Partita for 8 cellos.

Interlude Music Productions began as a publishing house for organ music. The organ catalogue consists mainly of lesser known, but interesting organ music – from the early 17th century organ tablature by Bernhard Schmid, via well known and lesser known 18th century composers, continuing through the unknown 19th and early 20th century organ works.

Interlude Music Productions has an unusual view pertaining to the choice of repertoire. Alongside of organ music, Interlude Music Productions also publishes unique music for the harpsichord, choir, strings and wind instruments. Ensemble editions always include a full score and parts.

The editions are of the highest quality and legibility, yet they are fairly priced.


During his student years, musician Willem Poot spent his free time searching through libraries for interesting, yet forgotten compositions. At that time research consisted of scouring through card-indexes and book shelves. Poot copied the music by hand or made photocopies of his findings.

At the end of the seventies Willem Poot found a collection of six fugues by Carl Philipp Emanuel Bach for which he made a transcription in modern notation. At the beginning of the eighties he found a Publisher for these fugues. After his appointment as a full time teacher at the Conservatory he no longer had time to pursue his research in the libraries. Interlude Productions was started in 1997 by Poot together with his (then) wife, thus enabling them the opportunity to publish sheet music independently. Interlude’s first editions, Krebs’s Eine Nachahmung der Nachtigall (Imitation of the song of the nightingale) and Rinck’s Organ Variations op. 90, were published in 1998.

Pavana care Lachrimae in tablature

  Organ tablature
Willem Poot came upon a manuscript in the archives of a library containing an organ tablature from 1609. Although he was not able to read it, the manuscript appeared to be an arrangement of a piece he knew. This prompted him to learn how to read tablature notation. Once an edition of this tablature had been transcribed, he then became interested in the organ tablature by Bernhard Schmid, printed in 1607. This tablature consisted largely of arrangements of period, choral music. He detected a lot of printing errors in Schmid’s tablature. As a result he began searching for the original pieces. He travelled from Brussels to Gdansk, and from London to Rome to study the original scores. The knowledge obtained allowed him to make the necessary corrections in Schmid’s tablature. He then (re)published the original choir music.

Further investigations

Having accompanied his cello playing daughter in the well known Sonata in g minor by Henry Eccles, Willem became astonished by the bad taste in which the available accompaniment had been arranged. In London he found the original score of Eccles’ music. The original piece appeared to have been scored for violin and basso continuo. This became the basis for the Interlude publication of Eccles’ Sonata for the Violin. Subsequent versions for cello, viola and oboe were published, always containing a simple continuo part, instead of an extravagant, romantic piano accompaniment. Thanks to Eccles, Willem Poot discovered the ‘Allettamenti’ by Valentini.

From card-index box to computer
With the arrival of the computer, the traditional card-index box became outdated. From that moment it became possible to search in on-line catalogues of libraries throughout the entire world. At the same time, the computer rendered pencil and music paper superfluous, with music notation software taking its place. Willem Poot uses Capella software to make his scores.

As of 2005 Interlude Music Productions had only 10 editions in its catalogue. Shortly thereafter the amount of publications expanded enormously. At the beginning of 2011 the Interlude catalogue consisted of more than 110 editions, with many more being planned!
