The ukulele is the most widely recognizable Hawaiian musical instrument. However, many more Hawaiian instruments have been used in traditional and modern Hawaiian music, including the slack-key guitar and the steel guitar. Traditional Hawaiian musical instruments have included percussion, string, and wind instruments created from plant materials. Dried gourds, bamboo, wood, coconuts, and shells are common materials. Other natural materials, such as shark skin, have also been used.
