I'm not sure about the insides of the piano but you might try consulting:

1) J.T. Schwartz, M. Sharir, "On the Piano Movers Problem I: The Case of
   a Two-Dimensional Rigid Polygonal Body Moving Amidst Polygonal Barriers,"
   Communications on Pure and Applied Mathematics, Vol. XXXVI, 1983.
2) J.T. Schwartz, M. Sharir, "On the Piano Movers Problem II: General
   Properties for Computing Topological Properties of Real Algebraic
   Manifolds," Rept. 41: New York University Department of Computer Science,
   Courant Institute of Mathematical Sciences, N.Y., 1982.
3) J.T. Schwartz, M. Sharir, "On the Piano Movers Problem III: Coordinating
   the motion of Several Independent Bodies: The Special Case of Circular
   Bodies Moving Among Polygonal Barriers," Rept. New York University

   N.Y., 1983.

Take this advice with a grain of salt, but it really is an interesting problem!
