The Electric Piano part calls for an instrument with variable tremolo or vibrato. Recommended is the Fender Rhodes electric piano. Volume levels between electric piano and grand piano should be comparable. Electric piano should not dominate the ensemble. Certain parts of the score call for improvisation.
Instructions are self-explanatory.
The instruction to imitate another improvisation implies approximate imitation, relating more to figuration and style, than to actual pitch or range. Movement VII incorporates a 12th century plainsong hymn as well as a Pavanne by Pierre Attaignant. The ragtime fragments in the piece are original. Dynamics should be closely adhered to, even if in places some instruments may be briefly covered by other louder instruments. All instruments are notated at playing, i.e., transposed pitch where applicable.
