Yiannis Chryssomallis, known professionally as Yanni, is a Greek composer, keyboardist, pianist, and music producer who has spent his adult life in the United States. He displayed musical talent at a young age, playing piano at the age of 6. His parents encouraged him to learn at his own pace and in his own way, without formal music training. The self-taught musician continues to use the "musical shorthand" that he developed as a child, rather than employing traditional musical notation. His breakthrough concert, Live at the Acropolis, yielded the second best-selling music concert video of all time. Yanni's compositions have been used on commercial television programs, especially for sporting events. Influenced by his encounters with cultures around the world, Yanni has been called a "true global artist" and his music is said to reflect his â€œone world, one peopleâ€ philosophy.
