Was Grieg's incidental music to Peer Gynt meant to be played WITH the play?

The Wiki entry on incidental music points to several examples. Mendelsohn’s Mid-summer night’s music was meant to be played along with and during the play, for example. But it’s not clear to me if that was the case with the incidental music to Peer Gynt. Is there a source that clarifies how the music was intended to be performed, with regard to the play? I can’t find anything that tells me. Thanks, dopers. xo,

Yes, Grieg composed the music to accompany the play, and they both premiered at the same performance.

The much-loved and familiar Peer Gynt Suites are later re-workings, but they draw on the original score for the play.

The Wikipedia article for In the Hall of the Mountain King says it was “composed by Edvard Grieg in 1875 as incidental music for the sixth scene of act 2 in Henrik Ibsen’s 1867 play Peer Gynt,” so clearly it was performed during the play. Anyway, that’s what incidental music means:

Not only is is the Peer Gynt music supposed to be heard in the play, it’s practically a wall-to-wall score. Ibsen wanted a ton of music in the play, and wrote a long letter to Grieg with detailed descriptions of what scenes required music. Here’s an excerpt:

(I’m quoting from this article, which is available on JSTOR if your local library provides it.)

Yeah, I own a CD of the complete incidental music for Peer Gynt.. The Suite is much more easy on the ears.

This. And the play itself needs a condensed version.
