Light in The Piazza Key Change?

Hello! As I know that many on these boards are fan of the show (and that Adam Guttel is a lurker here), I felt like this was the best place to ask.

So I was doing some repbook work, going overstuff, you know the drill, when I came across something a little confusing. I was practice ‘The Light In The Piazza’ when I realized the sheet music (which came from the score) I was working off of was in the key of C major and, in the cast recording, Kelli sings it in D major.


Did the key change when it went on tour to be more easily attainable for the actress? It makes sense as it’s happened before (two examples I can think of is Pulled from The Addams Family and So Much Better from Legally Blonde). I was just wondering if anyone could verify this?

(also Mr. Guttel, if you’re reading this, thank you for creating the masterpiece that is Light in the Piazza)

Keys are often adjusted when published for the mass market in order to make them more accessible to a wider range of musicians/singers. Heck, they're adjusted a lot throughout the writing/rehearsal process to play to the strengths of the cast originating the piece.
