Overview
Internationale Musikverlage Hans Sikorski is a German music-publishing company whose activities center on the publication, licensing, and administration of musical works. Founded in 1935, the firm developed a catalogue spanning both entertainment music and contemporary serious music, with a stated emphasis on new music from a wide range of countries. Its repertoire is broader than a conventional classical sheet-music list: it includes chamber and orchestral compositions, stage works, musicals, and film music, alongside popular and entertainment-oriented material. The company has historically been associated with Hamburg, where it was formerly headquartered, and is now based in Berlin. Its international orientation is reflected in the breadth of its represented repertoire and its work with composers and works from outside Germany. The Sikorski name is therefore used both as a publishing identity and as a rights-management presence in the professional music ecosystem, serving composers, performers, conductors, ensembles, theatres, broadcasters, and other users who require authorized scores, parts, editions, or performance rights. A notable characteristic of the company is its commitment to contemporary composition. Rather than limiting its catalogue to established repertory, Sikorski has maintained a role in bringing newer works to performers and institutions. Its catalogue structure connects the practical needs of professional music-making—such as orchestral materials, chamber editions, and stage scores—with the commercial and media applications of music for musicals, entertainment productions, and film. The company’s history also intersects with the complicated history of German music publishing during the twentieth century. Scholarship on music publishers during the National Socialist period has examined the activities of Hans C. Sikorski and the role of the Cautio Treuhand in the process described as “Aryanization.” That historical context is part of the broader record surrounding the Sikorski publishing enterprise and should be considered separately from the company’s later catalogue and international publishing activities. As of June 2019, Internationale Musikverlage Hans Sikorski had become part of Concord, an international music company with interests in publishing and recorded music. The transaction placed the Sikorski catalogue within a larger global music-rights group while preserving Sikorski as a recognizable publishing imprint. Publicly available reference material does not establish a separate current chief executive, detailed financial results, or a complete account of all catalogue acquisitions, so those fields remain unspecified here.
History
Internationale Musikverlage Hans Sikorski was established in 1935 as the music-publishing firm of Hans Sikorski. From its beginnings, the company operated across more than one musical category. Its repertoire included entertainment music as well as contemporary serious music, positioning the publisher between the commercial music market and the professional concert-music world. The firm’s historical development belongs to the wider story of German music publishing in the twentieth century. The activities of Hans C. Sikorski and the relationship between the publishing enterprise and Cautio Treuhand have been examined in scholarship on music publishers during the National Socialist period and in exile. That research discusses the process commonly referred to as “Aryanization,” making the company’s early history a subject of historical inquiry as well as publishing history. The available reference material does not provide a complete chronological account of individual transactions, ownership changes, or catalogue transfers, so those details are not expanded here. In the decades after its establishment, Sikorski built a catalogue that reached beyond a single national or stylistic market. The publisher has been associated with works by composers from many countries and with a continuing interest in new music. Its catalogue encompasses chamber music, orchestral music, and stage works, while also extending to musicals, film music, and entertainment repertoire. This combination gave the company relevance to concert organizations, ensembles, theatres, performers, broadcasters, and other users of licensed musical material. The company was formerly headquartered in Hamburg and later became based in Berlin. The change in location did not alter the central identity of Sikorski as an international music publisher. Its business has been organized around the development and dissemination of musical works, including the provision of scores and performance materials and the administration of associated publishing rights. A major corporate turning point came in June 2019, when Sikorski became part of Concord. The integration connected the long-established German publisher to a larger international music company. Sikorski nevertheless remained identifiable as a publishing name and catalogue within the broader Concord structure. Public reference material does not document a subsequent rebranding, closure, public listing, or detailed change in the company’s publishing scope. The business is therefore treated as active, with its contemporary status understood through its continuing association with Concord.

Classical music publishing
Chamber music
Sikorski publishes chamber repertoire for small ensembles and professional performers.

The repertoire is connected to the publisher’s wider commitment to contemporary music and international composers.
Classical music publishing
Orchestral music
The orchestral catalogue includes large-scale concert works and associated performance materials. Such publishing typically serves orchestras, conductors, festivals, and concert institutions that require licensed scores and parts. Orchestral music is one of the principal categories identified in descriptions of the Sikorski repertoire.
Stage and musical-theatre publishing
Stage works and musicals
Sikorski’s catalogue includes stage works and musicals, extending its business into theatrical performance. These works may require coordinated licensing and performance materials for theatres and production companies. The category illustrates the publisher’s combination of contemporary serious music, entertainment music, and dramatic repertoire.
Screen-music publishing
Film music
Film music is another identified area of the Sikorski repertoire. The company’s role in this field involves publishing and rights-related support for music connected with film and audiovisual use. Public reference material does not specify a complete film catalogue or individual titles in sufficient detail for listing here.
Entertainment-music publishing
Entertainment music
Alongside contemporary serious music, Sikorski publishes entertainment music. This broad category complements the firm’s concert, stage, and screen repertoire and gives the catalogue reach across multiple professional and commercial uses. The available sources do not provide a comprehensive breakdown of styles, artists, or individual product series.
Controversies
Historical examination of publishing activities during the Nazi era

Sikorski and the role of Cautio Treuhand in the process described as “Aryanization.” The available sources identify this as a subject of research and historical context, but do not provide enough detail here to characterize a specific contemporary scandal or a complete sequence of events.
