Playing mandolin - 4K 影片檔

A mandolin is a stringed musical instrument in a pear-like shape, and can have a bulging or straight back. From the cordophone family, it has double-colored, that is, four pairs of strings, and its tuning is in the same way as the violin: Sun, D, A, Mi. The origins of the mandolin date back to 16th-century Italy, and link it to the premier.
