A tripod includes a body, three legs, a connecting bracket and a post. The body has a top surface, and the connecting bracket is attached to the top surface of the body. The post has a top end and a bottom end, and the bottom end of the post is pivotally attached to the connecting bracket. The three legs are attached horizontally to the body. Two of the legs are pivotally attached to the body such that the legs can be pivoted away from each other within an angular displacement. Consequently, the tripod will stand firmly on the ground to support an object such as a sheet music holder.
