This document discusses structural musicality in swing dancing. It explains that structural musicality involves fitting dance moves to the overall structure and patterns of music, such as changes in tone, texture, and recurring rhythmic ideas, rather than interpreting music note-for-note. Common song structures for swing like 12-bar blues, 32-bar AABA form, and verse-chorus form are described. The document provides tips for dancers to identify changes in a song's structure through listening for chord changes, builds, breaks and hits in order to match these structural changes in their dancing.
