His recognition that pitch and duration could considered as part of the same acoustic phenomenon led him to experiment with simultaneous layers of tempi, for which three separate ensembles, each with its own conductor, were required.
Nine musicians and a conductor were required to recreate the complicated arrangements, including the four members of the Dave Brubeck quartet (which played a nimble, spirited set to open the show) and William O. Smith, the adventurous clarinetist who was a key member of the original octet.
It's a work in which the two speakers, the soloist, and the conductor are required to take part in a gestural, physical "action", to stamp their feet and perform star-jumps, to assume the lotus position while reciting passages from Ecclesiastes and the Grand Inquisitor's monologue from Fyodor Dostoevsky's The Brothers Karamazov.
Two conductors were required: MacMillan and Eamonn Dougan, associate conductor of the Sixteen (guest artists at the Tryst).
Additionally stretchable conductors are required which do not significantly impart the mechanics of the actuator.
Sea return is required but the overall solution is far less expensive than using a bespoke multi-conductor umbilical design.
Metal boxes must be grounded; so a ground conductor will be required at least to be extended into a box to re-establish ground continuity to the box and in the case of a circuit leaving a grounded box via knock out with reducing washers.
Upper crustal conductors (C2, C3) are required to explain the short period data.
This conductor is also required by both of the modes.
The C-4 conductor is possibly required to explain out-of-quadrant phases in the YX component at sites Y200, Y210, and Y220 because the anomalous large phases are not explained when the C-4 conductor is filled with 300 Ω m (Figure 3).
