A dolceola is a musical instrument resembling a miniature piano, but which is in fact a zither with a keyboard. It is used in traditional holy blues and has an unusual, angelic, music-box sound. Dolceolas were made by the Toledo Symphony Company from 1903 to 1907.
Paul Mason Howard accompanied Lead Belly on dolceola on some of his 1944 Capitol Records sides. A listen to those recordings, collected under the title Grasshoppers In My Pillow, reveals the characteristic clatter of the dolceola's three-level keyboard action.
The gospel and gospel blues musician Washington Phillips (1880–1954) has been said to have played a dolceola on his recordings, but his instrument was in fact called a "dulceola", and was a home-made fingered fretless zither.
