Conversation so far:
What is high step?
HBCU bands utilize the traditional "ankle-knee" high step and music selections are largely based on R&B, hip-hop, and contemporary popular music.
What else did they utilize in band?
In addition to traditional drill formations, HBCU bands feature heavily choreographed dance routines as part of their performances.
What are some other traditional drill formations?
Many of these bands may have a twirler line and/or a dancer line, but not necessarily flag twirlers.

Question: What else does the line consist of in the band?
Self-contained rewrite: What else does the line consist of in the marching band, other than High Step?
