This arrangement focuses on the jazz-infused sentimentality of Gershwin’s aria. It is distinctive for its use of colorful harmonic extensions and the requirement for a highly idiomatic, bluesy touch.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: a true singing tone, with the melody floating above the accompaniment; rubato that must breathe naturally without losing the pulse; and chord voicing — bringing out one note inside a handful of others.
Beyond that, expect careful pedaling — clarity depends on the foot as much as the fingers.
The performer must utilize advanced pedaling and touch to recreate the vocal phrasing and blues nuances of the original.
