A sheet music page turning device includes a base which supports a vertical shaft upon which a plurality of page holder elements are rotatably mounted in an annular guide member. A number of sleeves are mounted rotatably on the vertical shaft and are operatively connected to the page holder elements. A retaining pin prevents advance of the page holder elements along the guide member. A foot controller or alternatively, an electric motor is operatively connected to the retaining pin to permit manual or automatic release to thereby enable the page holder elements to advance and the pages to turn.
