Nana Mouskouri (Greek: Nάνα Μούσχουρη, ), born Iōánna Moúschouri (Greek: Ιωάννα Μούσχουρη, ) on October 13, 1934, in Chania, Crete, Greece, is a Greek singer who is believed to have sold more than 350 million records worldwide. She was known as "Nána" to her friends and family as a child. (In Greek her surname is pronounced with the stress on the first syllable – MOOS-hoo-ree – rather than the second.)
Mouskouri was sometimes described as Europe's answer to Barbra Streisand; her distinctive, angelic soprano voice was the result of having been born with only one vocal cord. Her repertoire supported the mainstream appeal she aimed for: jazz standards, well-known pop tunes from before and after the rock era, French cabaret chansons, movie songs, classical and operatic repertory, religious music, folk songs from her native Greece and elsewhere.
She has recorded songs in many languages, including Greek, French, English, German, Dutch, Italian, Portuguese, Spanish, Hebrew, Welsh, Mandarin Chinese, Maori and Turkish.
