Kos, Božidar: Spectrum 

 

 

Basic information

 

Notes

  • Program notes: 

    The title refers to the harmonic or overtone spectrum, which forms the basis for
    the vertical organisation of pitch in this work. Musical material has been mapped
    onto the harmonic spectrum of 32 harmonics. Each successive material has been
    mapped onto aspectrum of a different fundamental, creating thus a succession
    of incomplete or defective spectra, each belonging to another fundamental.
    This composition is based on an earlier work with the same title for bass clarinet,
    marimba and tape, where the tape material consist of pure harmonics on one
    hand and of complex FM sounds-on the other. Whereas the harmonics are in
    perfect harmonic relationship with each other, the organisation of FM sounds is
    based on the chromatically tempered spectrum, creating thus some incongruity
    between the two systems. The same principle is used in this work whereby some
    instruments of the orchestra are playing pitch material that belongs to the
    harmonic spectrum and others material that belongs to the chromatically
    tempered spectrum. Correspondingly such incongruence appears also between
    the pitch material played by the bass clarinet and the one played by the
    marimba.
