The roof 28 includes a front roof 280 that covers a front portion of the interior of the grand piano 20 and a large roof 282 that covers other portions. The front roof 280 is supported by the large roof 282 so that it can be folded rearward.

The grand piano music stand 10 includes a music score placement unit 12 that is arranged on a frontal 22 of the grand piano 20. A music score is placed on the front side of the music score placement unit 12. The material constituting the musical score placement unit 12 is not particularly limited, and for example, a metal material such as Al or Ti, a carbon material, or wood can be used.
The musical score placing part 12 has, for example, a flat plate shape. This makes it easy to reduce the weight of the grand piano music stand 10. Moreover, the planar shape of the musical score placement part 12 is designed so that the lower side becomes a linear shape, for example. Thereby, it is possible to stably arrange the music score placing portion 12 on the front heel 22. Here, the planar shape of the musical score placement unit 12 refers to a planar shape in a plan view viewed from the normal direction of the musical score placement unit 12 plane.
