The harp is a string instrument whose strings are plucked directly with the fingers. Mexican harps vary in size, tuning, construction, and musical role: regional traditions include the arpa jarocha and the larger harps used in parts of western and southern Mexico. Depending on the ensemble, a harp may carry a melody, outline harmony, or articulate rhythmic patterns. Its sound should not be treated as evidence of one particular region or genre without additional documentation. This category brings together recordings associated with harps and offers a point of comparison between local playing techniques, ensemble combinations, and the ways string instruments have been adapted across Mexican musical practices.
