If you zoom on in these photos, you can see that the toy harp is made by Schoenhut Piano Co. A quick google tells us the 15-string toy harp with its bench costs $150. According to the company’s website, Schoenhut has been making toy pianos since 1872. The brand boasts that its miniature instruments have been used by the “who’s who in music” and by “fine-tuned toddler[s].” Based on photo evidence in the site’s “Gallery of Stars,” this claim is very true. Bruno Mars, Pharrell Williams, Alicia Keys, The Lumineers, and Tom Waits are shown playing around on the tiny pianos, as well as the babies of stars like P!nk and Mariah Carey. Depending on the size and number of keys, Schoenhut grand pianos can cost anywhere from $65 to $250.
