How to pronounce“perturbedly”in English

“[T]o those who are much alive to the effects of music, airs and tunes often come back, in the commonest pursuits of life, to vex, as it were, and haunt them. The music, once admitted to the soul, becomes also a sort of spirit, and never dies. It wanders perturbedly through the halls and galleries of the memory, and is often heard again, distinct and living as when it first displaced the wavelets of the air.”
