Why factory construction matters

An acoustic piano combines wood, felt, metal, tension and precision mechanics. Moving one safely means respecting the instrument as a musical machine, not furniture.

Parts buyers should understand

  • Soundboard: affects resonance and can be sensitive to humidity history.
  • Pinblock and tuning pins: determine whether tuning can hold.
  • Action: keys, hammers and regulation affect touch and response.
  • Cabinet and plate: contribute weight and moving complexity.
