Some audience members jeered during Ms. Mohawk’s performance of her “Appointment With a Dream,” which involved her own ethereal take on scat singing.

The vocal improvisations of scat singing greats like Louis Armstrong, Ella Fitzgerald and Cab Calloway provided inspiration, though here, of course, the effect is precisely scripted.

On the one hand: the young genius-artist-virtuoso, who perfected the arts of swing, scat singing, and improvisational solos, hitting trumpet notes so high they tickled God’s toes.

And later in the suite, during the explosive, uptempo penultimate movement, “Resilience,” she channeled the fiery sense of artistic expression made possible by the school, with an inventive solo of scat singing.

Fitzgerald’s scat singing rivaled the improvisations of instrumentalists.
