GR translation: during recitatives or releases

[Mike Jing]

V129.28-32, P132.1-5   So the pure countertenor voice was soaring, finding
its way in to buoy Jessica’s heart and even Roger’s, she guessed, risking
glances at his face sideways and up through brown ghosts of her hair,
during recitatives or releases. He wasn’t looking nihilistic, not even
cheaply so. He was . . .

Is this the correct meaning of the word "release" here?

*g.* *Jazz*. A passage of music that serves as a bridge between repetitions
of a main melody.

I know it's not Jazz, but I can't find anything else that's more
appropriate.
