The 3 important steps for the perfect piano tuning


I’m Jens Witter, your piano doctor (having an actual PhD in Musicology).
My passion is bringing harmony to people’s lives.

Tuning a piano is a specific process that adjusts the tension of the strings using special tools. The strings must be stretched to a certain point so that they vibrate in harmony with each other according to acoustic laws and customs.

Fine tuning requires an assessment of the vibration interaction among notes, which is different for every piano.

Pianos are usually tuned to an equal temperament, involving the Pythagorean Komma.The result is well known in "Das wohltemperierte Klavier" from Johann Sebastian Bach.

The foundation of piano tuning is usually a chosen fixed pitch which is A440 Hertz.

I am tuning by ear and can adjust a sharper treble or flatter bass to your preferences or visa versa. Any tuning can be done to accompany other instruments.

And yes, they can be tuned,
if you own the right tools
and know how!

It doesn’t matter how modern or sophisticated an electronic tuning device might be, you will hear the difference and you will not be satisfied with a tuning done with an electronic device.

If you own an antique piano, square piano, antique or new harpsichord, pump organ, or any other rarity I will tune such pianos as well. And yes, they can be tuned, if you own the right tools and know how!

In some cases, the tuning might not hold due to the age of the instrument. Then I will restore your treasure and family heirloom, it most definitely has not to go to the dumps! I am equally excited to work on your regular upright or grand piano – any age, any size, any brand as long as it is an acoustic keyboard instrument.

The average piano has 225 strings. Each string has a different frequency and pitch and must be tuned to the other strings of the piano. These strings produce the sound of your piano.

Over time the strings stretch due to tension and humidity fluctuations which causes the soundboard to shrink and expand. The movement of the wood is in direct correlation with the humidity and causes the piano get out of tune.


In the 1980s, I tuned for the German Central Broadcasting Station in Leipzig (East Germany).

From 1990 – 2002, I was the piano tuner for the Royal Courts for His Majesty Prinz Phillip Konstantin zu Hohenlohe-Schillingsfuerst in the castle of Schillingsfuerst.

Here in Tucson, I tuned the pianos for the Emphi School District for many, many years. Currently, I am tuning and servicing the former White House piano from President Calvin Coolidge in Los Angeles.

My customers range from professional pianists to piano students at any ages from every walks of life.

Remember, anyone can pick up a tuning hammer and advertise themselves. These are not necessarily experienced or trained piano technicians. It requires knowledge, skills, passion, and attention to details to extract the very best from every piano.


A regular tuning takes about one hour. Concert tunings can take more than twice the time.

A piano should be tuned once a year. More often depending on demands and hearing.

If you tune your piano regularly your piano will be more likely to stay in tune for longer periods of time. It is important for students to play on an instrument that is in tune so they can correctly learn the pitches.

It is hard to be motivated to learn to play the piano when you don’t know if you are playing a wrong note or if the piano is just out of tune.

If the piano has not been tuned in a long time, the tuner has to raise the pitch of the piano which makes the pitch stay sharp and hopefully cause the piano to stay in tune when the strings naturally stretch over time. One or more follow-up tunings may be required. It will be more expensive and time-consuming to get the piano back into tune.

The best time to tune your piano is about a month after the season or weather has changed, usually after the monsoon here in Arizona.
Humidity is by far the biggest cause for tuning changes. Moving a piano, even from room to room, will definitely cause it to get out of tune and it will need to be re-tuned after it has acclimatized in about 4 weeks.

The piano should be kept away from direct sunlight, open doors and windows, fireplaces, evaporative cooler vents and such. A humidity control device is highly recommended.

In many cases, your piano requires more than just a tuning. Often a regulation, repairing of the action, or restoration of the acoustic system (cracked soundboard, loose pins) is necessary. Since I am a German certified piano maker, you are very fortunate that I offer these services, too!

I am proud to be a master piano maker with German diplomas and feel very privileged to serve you!

If I would be born a second time, I would be a piano maker again!
