Why does my Piano buzz?

The buzzing sound of a piano can be due to multiple reasons. Here are the key reasons on why this problem could occur to your upright, grand or acoustic pianos:

Foreign Objects Inside Mechanical Parts

  • Many a times, small objects such as pins, needles, clips, hard paper pieces or other smaller decorative objects are unknowingly kept on the piano lid or the body of the piano.
  • Younger kids learning piano might keep pens, pencils or pieces of paper which might eventually fall into the piano strings or get clogged in the action portion of the piano.
  • In such cases, such foreign objects interfere with the vibrations of the strings, hammers or the soundboard thereby causing a Buzzing effect on the piano sound.

Loose Parts of Your Piano

  • Sometimes, the piano strings are not tight enough and they might have loose ends.
  • Consequently, the sound of the piano notes are de-tuned and the player gets a buzzing effect while playing those notes.
  • Among the other parts, soundboard screws, action screws or even the pedal board hinges could be loose causing excess vibrations and thereby creating the similar buzzing effect on the sound.

Ageing Effects on Older Pianos

  • Due to cracks on the soundboard, rusting of steel strings or the action or pedal board hinges, the buzzing sound is often heard from your piano.

Room Objects Resonance and Vibrations:

  • Sometimes the various objects placed in the piano room vibrate when a piano is played.
  • Any loose items such as hangings, rings, artificial shelves etc. are prone to vibration and resonance in the same way as the piano strings vibrate during a playing session
  • These are therefore sources of external buzzing sounds not directly related to piano.
