LIVERMORE – Hailing from the Spanish Canary Islands, timple virtuoso Germán López will bring the traditional music of the islands, flavored with his own contemporary style, to the Bankhead Theater on Friday evening, Sept. 30. A diminutive five-stringed instrument intrinsic to the music of the Canary Islands, the timple (pronounced tim-play) is similar in size to the more familiar four-stringed ukulele but has a rounded shape and a fuller resonance. López is renowned for his performance on the timple and his music has been described as “small jewels ... ballads full of wonder and sensitivity” that express the joyful spirit of his native islands.
