Hapa haole music (lit. 'half foreign' in Hawaiian) is a genre of Hawaiian music which utilizes primarily English lyrics with themes and instruments attributed to Hawaii, such as the ukulele and steel guitar. Although it has its beginnings in the early 20th century with influences traditional Hawaiian music and American ragtime, the term "hapa haole" now comprises a wide variety of styles, including swing, rock and roll, and rap. It became greatly popular in the mainland United States in the 1910s, appealing to touristic perceptions of Hawaii as an exotic paradise.
