Description: Spectrum of the tenor bell at Winchester Cathedral as analyzed using FFT by Jonathan Harvey for his piece Mortuos Plango, Vivos Voco. Note that the major third in the second octave (F rather than E♮) is closer to the perfect fourth as is supposedly common in more modern bells. Sources Roads, Curtis, ed. (1992). Harvey Jonathan. "Mortuos Plango, Vivos Voco: A Realization at IRCAM", The Music Machine, p.92. ISBN 9780262680783. Harvey added, "a clearly audible, slow-decaying partial at 347 Hz with a beating component in it. It is a resultant of the various F harmonic series partials that can be clearly seen in the spectrum (5, [6], 7, 9, 11, 13, 17, etc.) beside the C-related partials." Downes, Michael (2009). Jonathan Harvey: Song offerings and White as jasmine, p.22. ISBN 9780754660224.
