The Ballad Repertory created by the Society typically includes a diverse range of materials that reflect the rich tradition of balladry. This can encompass:

1. Traditional Ballads: These are narrative songs that have been passed down through generations, often telling stories of love, tragedy, or historical events.

2. Original Compositions: New ballads written by contemporary songwriters that may draw inspiration from traditional forms but incorporate modern themes and styles.

3. Adaptations: Reinterpretations of classic ballads that may alter the lyrics or music to fit new contexts or artistic visions.

4. Cultural Variations: Ballads from different cultures and regions, showcasing the global nature of balladry and its various forms.

5. Performance Pieces: Works specifically designed for performance, which may include choreography or theatrical elements alongside the music.

6. Educational Materials: Resources aimed at teaching the history and techniques of ballad writing and performance, often used in workshops or community programs.
