Ellen Arkbro - For Organ and Brass (2017)

For organ and brass is comprised of two works by the Stockholm-based composer Ellen Arkbro. Both works focus on tuning, intonation and harmonic modulation. In previous projects, Arkbro composed for early music ensembles, wrote a series of durational pieces utilising synthetic tones and processed guitars, and, most recently, presented a work lasting 26 days at the Stockholm Concert Hall. for organ and brass looks back to Arkbro’s studies in Just Intonation with La Monte Young, Marian Zazeela, and their disciple Jung Hee Choi in New York, as well as with kindred spirit Marc Sabat in Berlin.
The title composition was written for an organ with a specific kind of historical tuning known as meantone temperament. It was only after locating an appropriate instrument—-the Sherer-Orgel dating back to 1624 in St. Stephen’s Church in Tangermünde, Northeastern Germany—-that Arkbro set about recording both for organ and brass and its counterpart, three.
“Hidden within the harmonic framework of the Renaissance organ are intervals and chords that bare a close resemblance to those found in the modalities of traditional blues music,” explains Arkbro. “The work can be thought of as a very slow and reduced blues music.”
The work moves gradually through a series of long, sustained tones played by the organ and in parallel by a brass trio comprised of horn, tuba, and trombone. Arkbro’s treatment of pitch resembles the tuning strategies of La Monte Young. The brass parts were performed by microtonal brass trio Zinc & Copper, a group whose repertoire has included works by C.C. Hennix and Christian Wolff.
