The harp is a plucked string instrument whose construction and musical role vary across regional traditions. In Mexico, harps appear in different ensemble settings, including son jarocho and arpa grande traditions, with distinctive sizes, playing techniques, and relationships to singers or other instruments. A catalog label such as “Arpa” does not by itself identify which regional type is heard. This category preserves the wording of the existing English-language term while grouping recordings associated with the harp. More specific recording notes, where available, help distinguish local instruments, performers, tunings, and repertoires without treating all Mexican harp practices as interchangeable.
