ROSE PETAL JAM is a cross-disciplinary, year-long project encompassing performances of Harry Partch’s earliest chamber music, mainly from 1930 to 1950, as well as commissions of new compositions influenced by Partch’s legacy. It also has an important research and education component, involving the adaptation of existing instruments and building of replicas of Partch’s unique sonic creations. Since 2017 we have added the following instruments to our growing ensemble - Adapted Guitar II and III (adaptation by luthier James Mumford), Tin Oboe (developed Lucas van Helsdingen), Mazda Marimba (various contributors), Diamond Marimba (Aart Strootman) and Harmonic Canon II aka ‘Castor’ (David Lavis). Investigations into the myriad manifestations of Partch’s early scores and biographical contexts inform the group’s constantly developing approach to performing his music. Scordatura has also presented many workshops for musicians and non-musicians alike, constantly exploring how Partch’s work can exist as a source of inspiration for new generations of composers, audiences and performers. Rose Petal Jam is supported by a.o. Performing Arts Fund NL, Fonds 21, Prins Bernhard Foundation, AFK (Amsterdam Fund for the Arts) Gaviniès Society, VSB Foundation.
