In a 2018 study of traditional Andean music, ethnomusicologist Sofia Morales analyzed the *caja*, a small hand-held drum played during agricultural festivals. Many scholars have argued that the instrument's primary function is strictly rhythmic, acting as a simple metronome for communal dances. However, Morales observed that players adjust their striking technique to produce specific resonant overtones that mimic the calls of highland birds during planting seasons. This subtle acoustic imitation does not merely accompany the ritual; rather, it actively integrates the natural environment into the performance. Thus, the *caja* serves a complex symbolic role, mediating the community's relationship with their ecological surroundings.
