Piano tuning and maintenance...

Pianos that are tuned regularly experience less stress during the tuning process. This results in a more stable and longer lasting tuning.

The key to a stable tuning is to (1) equalize the tension between the 4+ segments of a piano string, (2) properly set the tuning pin and (3) maintain a controlled environment.

Usually a standard tuning is required. However pianos that are not tuned regularly often require more work, ie. additional tuning(s) in order to reach acceptable stability - this is commonly known as a pitch raise.

If a piano has not been tuned in many years, expect that it will likely require a pitch raise.


  • Do not place pianos in direct sunlight, tuming instability and sun bleaching may occur.
  • Do not place in front of or next to a heating / cooling source.
  • Place an upright piano at approx. 10 cm from the wall.
  • No plants on the piano.
  • Place cups underneath all metal casters to protect your floor.
  • Adjust bench height so the pianist's forearms are slightly higher than the keys.


  • IT IS OK to place the piano on an outside wall.
  • IT IS OK to put a piano in a basement.
  • IT IS OK to let young children "play". They can't break it!
  • DO NOT use milk or vinegar to clean ivories / keytops (use a slightly damp cloth - no chemicals).
  • Waxing / stripping / painting the piano will not make it sound better.
  • Pianos that are not played still require periodic maintenance.

New pianos are not always better. Many are great instruments, however many are also known as a PSO (Piano Shaped Object). Older pianos are still great choices and are available at a much lower cost.

Often, partial or complete restoration of a good old piano is much more economical than buying a new, low-quality instrument. Once restored, it probably will have much better tone than the average new piano.

Before the tuning...

  • Remove all objects placed on the piano.
  • Make some room around the piano as some case parts will have to be removed.
  • Identify any problematic notes.
  • Avoid loud background noises during the tuning.

New pianos...

New pianos require a different tuning schedule. The settling of the wood structures such as the soundboard, bridges, pinblock etc. may cause the pitch to drop between tunings. Most manufacturers recommend 2-4 tunings during the first two years of ownership.

Why upgrade from digital...

  • Tone: You simply cannot beat the presence of an acoustic piano. Yes, the new digital pianos have sampled sounds obtained from top acoustic pianos, but their tonal qualities are lacking the soul of the traditional instrument.

  • The appearance, prestige and tradition.

  • Longer keys of acoustic pianos provide that balanced touch and control.

  • All acoustic pianos can be refined to improve the touch as well as the tone and are often adjusted to the pianist's requirements.

Facts about pianos...

Pianos are delicate instruments that require periodic professional attention...

Although there are only 88 keys, a piano has over 200 strings - one per note in the low bass, two per note in the upper bass, and three per note in the tenor / treble.

Tension averages approximately 160 lbs. per string. All together, the strings are stretched to a tension of 18 to 20 tons (close to 30 tons in a concert grand).

The strings gradually increase in thickness and length from treble to bass, and bass strings are wrapped with copper (older pianos may have steel wrapped bass strings) to produce a lower frequency by increasing the mass of the string.

There are often 5000 or more parts in a piano.

Humidity Control...

The room where your piano sits should be humidity-controlled.

Pianos that are subject to large humidity variations will usually go out of tune much more rapidly. Especially true in southern Quebec with our high humidity summers and very cold and dry winters.

Humidity control can be achieved by installing a Dampp Chaser system or by stabilizing the piano's environment; ideally around 20°C and 45% humidity.

Once under control, an annual tuning / verification is recommended.
