Over time, as your piano ages and is affected by changes in its materials and the effects of fluctuating temperatures and humidity, it will fall out of tune. This can lead to a minor change that’s subtle and hard to detect or a major one that can land harshly on even an untrained ear. Either way, a skilled tuner like John will help resolve the issue.

Piano tuning involves adjusting the tension of each string, ensuring each is in harmony with the others. Each of the more than 200 strings is attached at one end to a hitch pin and the other wrapped around a tuning pin. John turns the tuning pin with a lever until the desired pitch is reached.

The action or moving parts of your piano may require periodic adjustment to compensate for compaction, wear, and changes in the wood due to humidity. Piano regulation ensures each moving part operates as it should, and your piano remains responsive to your touch.

This process allows you to continue enjoying playing your piano and gives the feel of being fresh from the factory.


Your piano is a unique creation, regardless of how mass-produced it may be. Each one has a different tonal profile than another, and piano voicing keeps yours true and melodic.

Voicing adjusts the tone of your piano. A variety of techniques, such as reshaping, proper realignment, treating the hammers with chemicals, and sticking needles into them, are used to soften them and adjust the tone of your instrument.
