Performance Instructions
Notes:
Electronics:
Two channels of electronics are available on a Compact Disk. A high
quality system is to be used during performance. Any of the six versions
(timings are exactly the same) on the CD may be used. Differences are
only in mixing and timbre.
Performance:
A version is selected and the CD machine is put into play mode on a
cue from the performer. Once playback has begun, no further action is
required except to enter stop mode at the conclusion of the composition
(about 10:25).
Program
Notes:
A steering gear
is a unit of extreme simplicity. The steering tube revolves a cam, which,
in turn, engages with a taper peg fitted to a rocker shaft. This assembly
is enclosed in an oil tight casing which carries two ball bearings at
either end of the cam. These bearings are designed to carry radial and
thrust loads. When the steering wheel is turned, the tube revolves the
cam, which causes the taper peg to move over a predetermined arc, thus
giving the rocker shaft its desired motion. Attached to the rocker shaft
is a steering side and cross tube level, which links up with the steering
linkage. The steering is of the "three cross tube" type, having
a centre cross tube connecting the steering side and cross tube lever
to the arm on the idler shaft. Two shorter side tubes, one on either
side, connect the steering arms to the steering gear and idler levers
respectively. The composition was written for and is dedicated to Jesse
Langen.
