The author first portrays Scotty as timid on stage. He is sitting on his stool and performing without a great deal of energy. However, when the energy and positive reaction from the crowd hit him like a wave, he gains his confidence. He stands up and begins to perform with energy and enthusiasm. He is first described as a "quavering husk". It gives the image of him almost hiding like an ear of corn inside its protective husk. Then he is described as strong, charismatic and fierce - a significant change from when he first took the stage.
The best answer I see would be, "Language".
