Physical design based upon a 19th century ornamental globe, this celestial, networked instrument connects to and interprets solar messages received from the planets within our solar system, creating a virtual solar soundscape. The actual geographical position of the instrument and player on earth relates directly to a reference point on the instruments surface. Physically rotating the globe (which has a full x/y/z rotational range) alters your reference point in relation to the current position of the planets, and so alters the signals received. These signals are then processed through the instrument, with the players ability to influence the sound with wooden slides and stops modelled on old church organ operatives. Due to the vast density of solar information the instrument will receive a typewriter, again modelled on 19th century design, has been installed to be able to input parameters that filter the array of signals received. Other sounds used include the stylus placement for initial boot up along with electrical throbs of the tubes heating up; the movement of the globe and operation of the stops and slides corresponding with the changes in sound produced; and the subtle creaks of the wooden frame containing the globe itself. Solar information is received and interpreted by the instruments processors, giving the emitted sound its own unique colour and style. The aural ambience produced ranges from the colossal Jupiterian bass rumbles to the distance sporadic Plutonian signals that manage to reach planet earth. Due to the nature of these sounds the dynamic range of this instrument is vast, with sonic capabilities covering the full range of human hearing. For this to be apparent, the sound presentation must be listened to on a system able to handle this range. Space and atmospheric interference plays a part with signals received and processed varying in clarity and resolution. The sound piece presented aurally demonstrates the instrument in action. Initial boot up is followed by a short demonstration of the instruments capabilities along with operational sounds of the performer. The piece concludes with powering down.
