Did you see that? What was it? Students will have no problem imagining mysterious shadows with this lively yet mysterious-sounding solo. Written in D minor, the left hand is an excellent study of harmonic fifths and sixths. The right hand has root position triads, clusters and broken thirds. In A-B-A form, the two hands alternate with an ostinato rhythm in the A sections. The eight-measure B section is sequential, both rhythmically and melodically. The last four measures are faster and bring the piece to an exciting close.
