ABSTRACT:
The holders are attachable to the edges of planar support surfaces for music and serve to hold the music in place against the effects of wind, gravity and characteristics of the music material. Each holder comprises attachment apparatus and a spring arm extending from it to contact the music. In a preferred embodiment the spring comprises an arm portion and a pivot portion which, when the spring is relaxed, is at an 80.degree. angle to the arm portion. The pivot portion is carried in a hole in the attachment apparatus, the hole and pivot portion being inclined at a 3.degree. angle off of normal to the planar support surface angled toward the leafed material. The arm portion can thus be pivoted so that its end is either in or clear of the locations in which music is placed to be held. Height of the arm portion is adjustable by sliding the pivot portion in the hole in the attachment apparatus, thus accommodating variations in the thickness of the music material and allowing the arm to be positioned to lie flat against held material to allow free turning of unheld material.
