Yma Sumac
Yma Sumac (1922–2008) was a Peruvian-American singer known for an exceptionally wide vocal range and theatrical recordings inspired by Andean music.
Moises Vivanco: A Peruvian guitarist, composer, and bandleader who collaborated with Yma Sumac and helped shape her stage career. Vivanco was Sumac’s husband, musical collaborator, and manager during her rise to fame.
Vocal range: The span between the lowest and highest pitches a voice can produce or sing. Sumac’s reported range was central to the publicity and listening experience surrounding her records.
Peruvian music: The diverse musical traditions developed in Peru, shaped by Indigenous, African, European, and regional influences. Sumac’s repertoire and stage identity drew on musical forms presented as Peruvian.
Voice of the Xtabay: Yma Sumac’s 1950 debut studio album, arranged and conducted by Les Baxter. Its commercial success introduced her dramatic vocal style to a broad American audience.
Exotica revival: A later renewed interest in mid-century music that evoked imagined distant places and cultures. Collectors and musicians revisited Sumac’s orchestral albums as part of exotica’s reassessment.
Les Baxter: An American composer and bandleader associated with exotica and orchestral popular music. Baxter arranged and conducted Sumac’s early Capitol Records albums.
Whistle register: The highest vocal register, produced with a small opening of the vocal folds. Her rapid shifts into very high notes helped make performances such as “Chuncho” distinctive.
Andean music: Musical traditions from the Andes, including Indigenous instruments, regional styles, and later hybrid forms. Her recordings were promoted as evoking Andean culture, though they were theatrical arrangements rather than field recordings.
Chuncho: A composition recorded by Yma Sumac, featuring rapid vocal changes and orchestral accompaniment. The track is a concentrated example of her theatrical vocal and instrumental style.
World music: A broad marketing and listening category for music associated with cultural traditions beyond Western popular music. Sumac’s international circulation anticipates debates about how non-Western music is packaged for global audiences.
