The piano lamp on our grand piano provides the proper lighting to read the sheet music.
Why do I call it a "tipsy" piano lamp? A few hours after using the lamp, the right side (where the on-off switch is) has tipped down and ends up about four inches LOWER than the left side. I raise the right side so that the lamp is again level and it stays there -- for another few hours. And then the right side again ends up about four inches LOWER than the left side. Said another way, on its own, the lamp rotates clockwise about thirty degrees over the period of a few hours and comes to rest in that tipped position.
I know, you don't believe me. No one else does, either.
The grand piano lamp was shipped promptly and well packaged. I have a 100 year old grand in my living room and the lamp looks great on it. I added a line-dimmer and that works well. Now the sheet music lights up the world - only wish my playing was as good - I'll try harder now that I can see the notes.
