Why Does My Instrument Buzz When I Play It?


If you’ve begun to notice a buzzing sound while bowing or plucking one or more of your strings, your instrument might be in need of a sound post adjustment. Situated inside the instrument, the sound post makes contact with both the front and backplates, transferring vibrations between them and facilitating resonance. Because the sound post is held in place by tension alone and its precise position is crucial, an accidental jostling of your instrument could cause the sound post to shift, thus adversely affecting sound quality. Most violin shops are easily able to make the necessary adjustments to eliminate that pesky buzz and restore a smooth, beautiful tone!
