The Peruvian singer Yma Sumac had a vocal range of four or five octaves – far beyond most singers, and one of the widest ranges on record.
But back to Sumac. Her voice had a rich warmth that could stretch from very low breathy notes through to very high ones. Her song “K’arawi” (see below) jumps five octaves in eleven seconds. Sumac had an impressive career, including #1 hits, performances at Carnegie Hall, on film and in television.
