To adjust, and repair if necessary,

 the piano to the original factory settings

so the owner can fully enjoy the piano experience. 


Hammer Alignment

One of the things done when regulating is to align the hammers.  These two photos represent before and after pictures of hammer spacing.

Hammer Shaping

Another step done when regulating is hammer shaping.  This photo shows the deep grooves the hammer had before it was shaped and how the hammer should look after shaping.  The goal is to give the hammer a narrow striking point with no groves from the strings.

Damper Regulation

The keys have been removed from this grand piano to show the damper levers.
The damper levers are regulated using a Spurlock leveling tool.
This assures the dampers lift at the correct time.

Key Spacing and Leveling

Under each key, there are paper and felt punchings, and a pin. 
If adjusted properly, every key will be the exact same height and the spacing between the keys will be the same.

Felt Replacement

These photos depict the procedure for replacing felt, which is present wherever wood contacts steel pins.



REGULATION - this adjusts all the moving parts of the piano, back to the factory settings

REPAIR - broken strings or hammers can be replaced or repaired.  Missing or damaged felt can be replaced.


The pitch of the piano will be brought back to an A-440 pitch.  It may be necessary to perform a "Pitch Raise" if the piano hasn't been tuned regularly.   It will take 1-3 hours to tune a  piano.

Success! Message received.


We moved the piano business to Indianapolis in 2016 to be near our grandchildren.  I tune and service pianos in homes, schools, and churches.  I was trained and learned the latest techniques at NIU under David Graham and was mentored by Mark Foss of Elburn, IL, and further trained by Randy Potter of Bend, Oregon.  I have passed exams offered by the Piano Technicians Guild to assure all repairs are done correctly and  I am also a Certified Piano Life Saver Installer.


As the world slowly moves toward reopening, the Piano Technicians Guild and the Centers for Disease Control and Prevention (CDC) have specific suggestions for keeping piano owners and piano tuners safe.  You can view these at the following websites:

Your upcoming piano appointment – the Zanellato Piano Tuning and Repair Company wants you to know we value you and your business and look forward to serving your piano soon.  As we begin to schedule appointments and provide services, we ask that all our customers review the following information.  It’s our way of letting you know what we’re doing to help keep you safe and what you can do to help us do our job safely.

Rescheduling due to illness – If anyone in our family has a fever or other symptoms, we will contact you to reschedule the appointment.  We ask you to do the same regarding your family.

Here’s what we’ll be doing to keep you safe during your appointment.  Your safety is our highest priority!

  • Sanitization of all tools before and after each appointment.

  • Sanitizing hands prior to entering your house.

  • Cleaning and sanitizing your piano per the PTG guidelines.

  • Wearing a facemask and practicing social distancing.

  • An invoice can be emailed, rather than leaving a paper copy, if preferred

Here’s what you can do to make your tuning appointment productive and pleasurable and also help keep all of us safe.

  • Please make sure you and all others maintain social distancing.  Please keep the area where the piano is located free of children and pets.

  • Make a list of any piano issues you would like addressed and share them ahead of time.

  • Please remove all objects placed on top of the piano.  Remove all sheet music, knick knacks, pictures, and any other items from the piano.

  • If you prefer to remain contactless, please leave payment on the piano.

  • If you need extra precautions, please let us know.  We will gladly work to find a solution or reschedule your appointment to a future date.


Pastor S. - "Bill Z. did a  great job tuning our pianos at Thompson Road Baptist Church.  He is skilled, professional, and punctual.  We would highly recommend Bill to any church or individual needing piano tuning services."  

Dave K. - "Just got a chance to play my piano since you tuned it. It sounds great! The D key, that I was talking about, sounds great also!  It's been muddy for 12 years and you're the first one to fix it."

Kate M. - "Thanks so much Bill for bringing my girl back to life.  I played for hours last lost in the music; she sounds wonderful!  I'm so happy that our paths crossed."

Tony M, Nextdoor Neighbor - "I met Bill when he came over to check out my archaic piano.  He is super professional, matter of fact, and eager (very knowledgeable) to answer questions.  I would recommend him.  (I own a recording studio and am a lifetime professional musician.)"

Kelly H. - "We have a baby grand that has seen more moves than is good for it.  After the last move and some time spent in storage, it finally found its new home, reassembled incorrectly and badly out of tune.  Bill took such extra pains to correct the assembly issue and made it sound better than it EVER has.  I would highly recommend him."


David H, of Life Point Church - "Bill has been tuning our pianos (an upright and two baby grands) here at LifePoint Church since the summer of 2016 and I am super pleased with his work. He is very conscientious and takes the time necessary to get it right. We use brass, winds, and stings along with a rhythm section in our worship service so tuning is very important. Most of the individual players tune with their own tuner and when I double check it with the tuning of the piano, the piano is always dead on. Bill is friendly, kind, as well as professional and I highly recommend him for any of your piano needs!"
