PROGRAM NOTES: When Voyager 2 passed by Uranus in January of 1986 it returned photographs of a big, blue-green ball of gas with few readily discernible features. More recent observations from Earth-orbit have confirmed evidence of great winds and related meteorological phenomena in the atmosphere that is Uranus. More detailed conceptions of the Uranian environment, however, must remain in our imaginations, at least for now. |

TECHNICAL NOTES:
Vaporis Congeries Magnae (Great Gobs of Gas) was realized
in Csound on a Macintosh G4 laptop computer. The digital instruments used
to create the sounds include both formant wave synthesis (FOF) and frequency
modulation synthesis (FM) components. The pitches of the piece are tuned
in a 7-limit just intonation, with a few microtonal alternations in some
places where the arithmetic provides two or more possible tunings for a
given note. The virtual space in which the digital instruments are played
includes a reverberation created by convolving the sounds of the digital
instruments with the recorded impulse response of Wellin Hall in the Schambach
Center at Hamilton College, in Clinton, New York.
