What characteristic aligns with the behavior expected during the singing of the hymn?

The behavior expected during the singing of the hymn aligns with maintaining a respectful and dignified demeanor, which often includes not swaying. This characteristic promotes an atmosphere of reverence and focus on the lyrics and meaning of the hymn, allowing individuals to engage in the moment collectively.

Standing still emphasizes the importance of the hymn, reinforcing its significance rather than turning it into a casual or overly animated event. This contrasts with more interactive or movement-based behaviors, which could detract from the solemnity and unity intended during such a moment in an organizational setting like that of Sigma Gamma Rho.
