The lamp arm does swivel about 30 degrees left and right. The problem I think you might have using it at your piano is, the base must be set firmly on a horizontal surface. It might be difficult to adjust it out in front of your music and then tilt it back so the light isn't shining in your eyes. If this is the only use you have in mind for this lamp, you may want a different style. The light output, though, would be wonderful for music.
