In some cultures the balafon was (and in some still is) a sacred instrument, playable only by trained religious caste members and only at ritual events such as festivals, royal, funerial, or marriage celebrations. Here the balafon is kept in a temple storehouse, and can only be removed and played after undergoing purification rites. Specific instruments may be built to be only played for specific rituals and repertoires. Young adepts are trained not on the sacred instrument, but on "free-key" pit balafons.
