Yma Sumac was a Peruvian soprano. In the 1950s, she was one of the most famous proponents of exotica music. Sumac became an international success based on her extreme vocal range, which was said to be "well over five octaves at the peak of her singing career. Sumac recorded an extraordinarily wide vocal range of 5 octaves, 3 notes and a semitone ranging from E2 to Bb7. Recording restoration expert John H. Haley favorably compared Súmac's tone to opera singers Isabella Colbran, Maria Malibran, and Pauline Viardot. He described Súmac's voice as not having the "bright penetrating peal of a true coloratura soprano", but having in its place "an alluring sweet darkness...virtually unique in our time". I have always loved her music, as it brings memories of childhood back from my grandmothers house, who raised me till middle school, when both my parent were working. Travel Penguin's post got me to listening to Yma today, so why not share it. I can't think of a more beautiful sound flooding the joint on this sunny morning.
