. In the woodwind quintet, the Horn takes the role of the bass, the bassoon and clarinet cover the cello and viola, and the flute substitutes for the violin.

Analysis

Susan Feder's program notes of the St. Louis Symphony recording of this piece include imagery given by Tower regarding the title:
"The Island is remote, lush, tropical with stretches of white beach interspersed with thick green jungle. Above is a large, powerful, and brightly colored bird which soars and glides, spirals up, and plummets with folded wings as it dominates but lives in complete harmony with its island home."

Tower's analysis of Island Prelude divides it into three main sections, possibly fitting the sonata form

 begins its solo in measure 10 with sustained notes over the ebbing major 2nds, 4th, and 6ths. The use of consonant intervals maintains the sense of a "consonant landscape". Tower describes the oboe's presence as a "slightly more prominent and melismic line which in turn activates the surrounding held chords." Measure 12 breaks the consonance with the clarinet sounding a G# against the A in the bassoon and horn. Dissonant tension builds until the release at measure 15, then the tension begins again (m.21). The counterpoint develops into a second section, or B section, with more complex rhythm and independence of lines. At measure 54, superimposed tritone

 then begins to move downward (m.63), and the oboe recaps the running sixteenth and thirty-second patterns before resting (m.73). Chromatic steps, repetition, and dissonant leaps build to m90 where the oboe begins its flight of complex rhythm over spasmodic chords in the bass. The bass then imitates (m.97) parts of previous rhythmic ideas as the melodic line soars higher, building to measure 108 where all instruments hit a unison on C. A falling fifth pattern in the clarinet, horn, and bassoon brings the range back down and heavy counterpoint continues until the oboe returns on a high Eb trill (m.129). Three short chords sound under the trill and oboe plays the trill down an octave with each chord, ending on a low Eb. Here, the oboe begins its cadenza
