This device provides a stable platform for sheet music or instructional materials while playing a keyboard instrument. It typically attaches directly to the keyboard or its stand, positioning the music at an optimal viewing angle for the musician. These supports come in various designs, ranging from simple wire frames to more elaborate, adjustable models made of metal or plastic.
The use of such a support enhances practice and performance. It allows musicians to maintain proper posture, reducing strain and fatigue. Furthermore, it streamlines the reading process, enabling focus to remain on technique and musical expression. The availability of hands-free reading has significantly improved the efficiency and accuracy of keyboard playing throughout history.
