The 3rd and last "Studio V" podcast episode exploring the grand piano is now available. It features piano technician Reid Schaefer, who is an expert on piano maintenance and tuning. He has cared for my pianos for over 3 decades, as together, we have tried to fine "tune" the sound and performance of the various pianos I have had during my career as a recording engineer. 
This episode gets inside the instrument and examines the materials and inner workings of the grand piano and the variety of sounds it can generate. It is a bit technical and extremely informative.
