The most important part of Chapter 17 is trying to understand the music that Bud is hearing. Here are two videos. The first one is a man named Duke Ellington and his orchestra playing a song called It Don't Mean a Thing (If It Ain't Got That Swing).
Next is a video featuring Billie Holiday and Louis Armstrong. Listening to Ms. Holiday sing will give you an idea of what Miss Thomas may have sounded like. And the beginning of the video sort of starts with Mr. Armstrong "saying" something with his trumpet and Ms. Holiday answering him. (I'm not sure why the end gets cut off.)
