I Can't Believe That You're In Love With Me (arr. Kirby Shaw): Choral Instrumental Pak

Shaw's arrangement channels the infectious energy of classic jazz standards while keeping the rhythm section engaged and essential to the groove. The instrumental parts transform this tune into a vehicle where your rhythm section can shine, offering the kind of sophisticated comping and walking bass lines that make ensemble members want to come to rehearsal. For jazz choirs, this is the rare piece that balances accessibility with legitimate musicianship.

The arrangement radiates warmth and swing, with instrumental parts that establish a relaxed but locked groove underneath the choir's lines. There's a sense of sophistication and ease, the way good jazz feels when everyone is listening to each other and playing with intention rather than rushing through the changes.

Jazz choirs and show choirs looking for repertoire with serious instrumental grooves and authentic jazz styling. Directors who want their rhythm section actively involved in the musical conversation rather than simply providing accompaniment will find this arrangement particularly rewarding.

• Lock the eighth-note feel between piano and bass before rehearsing with the full choir; a slight push or drag in the rhythm section will expose the whole arrangement.
• Give your rhythm section room to breathe and interpret the changes. Shaw's charts thrive when musicians add articulation and dynamics choices that feel conversational rather than locked in.
• Use dynamics in the horn parts (if included in full instrumentation) to frame the choir's entries, creating call-and-response moments that pull the audience into the performance.
• Encourage your soloists to reference classic jazz singers performing this standard; the phrasing and time feel in those recordings will inform how your ensemble voices the melody.

Pair this with other standards-based material for a jazz-themed concert segment, or use it as a showcase moment that highlights your ensemble's instrumental capability. The familiar standard appeals to audiences while the arrangement's musicality keeps experienced musicians engaged.
