Final answer:
Crossing arms during a hymn is a gesture found in various traditions, often symbolizing humility, penance, or spiritual connection. Different cultures and religious practices have their own specific gestures and postures during hymn singing that convey respect or supplication.
Step-by-step explanation:
The tradition of crossing your arms during the singing of a hymn can be associated with various cultural or religious practices. In some traditions, such as in certain Christian denominations, crossing one's arms across the chest is a sign of humility or penance during the reception of blessings or sacraments. The gesture might also symbolize a personal or spiritual connection to the content of the hymn being sung. For instance, the orant position, with arms outstretched or uplifted, is an ancient posture of prayer and can be seen in early Christian art, symbolizing an appeal to the divine. Other traditions might prescribe specific gestures associated with liturgical practices, such as the raising of arms in expressions of joy or supplication as seen in Shaker dances, or maintaining more formal postures as recommended by Quintilian for orators. While the context and the hymn itself can influence the specific way arms are crossed, the underlying intent is to engage in a posture of reverence, respect, or worship during the hymn.
