Dear Pianoexpert, my son Christian has recently bought a second-hand Yamaha C7 grand piano, I was asking you if there is an orientation direction that the wheels of the three legs must have, i.e., should they be arranged radially or parallel to the ground?
Thank you for your response regarding this matter.
The wheels must be arranged towards the outer diagonal (relative to the center of the instrument viewed from above). Best wishes for the new instrument
