I remember playing this terrible, clunky upright piano for a high school recital. My school at the time only had courses for traditional band instruments, but since I was in grade 9 piano at the time, the music teacher invited me (well, more like volunteered me) to perform on the piano at the annual performing arts recital, even though piano wasn't part of the curriculum back then.
The venue had the aforementioned piano, which we used. It was old, not tuned (at least, not very well), and the loudest I could achieve from it was probably a mezzo-forte (which pains me, because I've always been complimented for my expressiveness and use of dynamics). The keys were clunky and difficult to press, and every time I used the damper pedal, the keys shifted noticeably. Speaking of the pedals, for some reason they were unusually high off the floor, meaning every time I had to lift my foot off the pedal, I had to physically lift my entire foot off the floor.
It was universally agreed upon after the recital that the piano was terrible was never to be used again by our music department.
