Originally conceived as a vocal solo for a classically trained soprano. Now, the vocal palette has been expanded for both SSAA and SATB choirs. Along with the expanded number of voices, the style has also expanded to include a folk-like style for the lower voices, an angel-like quality for the upper voices and an accordian, wind instrument and percussion accompaniment to embellish the piano part. This can also be accompanied using the chord symbols for a more free and improvisatory affect.
