Q Questions &  ANSWERs


How did you decide to get in your line of work?

  • Raised in a family of all musicians and piano tuners I began learning very early about the business. After high-school I realized it was a profession that would keep me close to music while learning a skilled trade for income.Then I discovered I was good at it,and my interest in piano service grew.I enjoy what I do.If you can enjoy yourself at work,well, I think its a good thing.Makes for good results as well.I have Brothers, uncles,cousins, nieces and nephews scattered across the lower 48 who are piano repair service tradesmen\women.Shall I say, it runs in the family

What questions do customers most commonly ask you?

  • Why do pianos go out of tune? A well maintained piano(tuned a minimum of twice yearly)is primarily affected by changes in humidity and temperature.High humidity is absorbed by the wood frame and soundboard itself which causes the wood to swell and the soundboard to flex upward towards the strings.causing the piano to pull sharp,the opposite is true when the humidity drops to low levels which results in the pitch dropping and the piano becomes flat of concert pitch. The change in seasons of the year is probably the highest contributing factor to the changes of the environment in the home.Summertime the A/C is on which removes humidity in the air. In winter the heater tends to also remove moisture from the air. Both seasons are usually times of high humidity levels depending on location,i.e. coastal vs.desert regions etc. Spring and Fall usually brings frequent thunderstorms (again subject to location) which brings about rapid fluctuations in humidity and temperatures,The net effect is still the same the piano begins to go out of tune.Each time the piano goes through these changes ,the pitch rises then drops,it rises a little less each time and drops a little more,until it has become to flat to correct with a single tuning. Now we must ruff tune to restore the piano to concert pitch of "A" 440 by actually pulling it a little sharp of pitch and then going over a second time to fine tune to "A" 440

What advice do you have for a customer looking to hire a provider like you?

  • Professional and Qualified service is critical to the longevity and maintenance of your piano.Although I am not currently a registered piano technician in the guild(was at one time)in most cases since there are no Licensing laws governing the piano service business i.e electricians,plumbers etc. Your best bet for getting qualified service is to call me:-) or by locating a registered piano tuner near you.At least you have some assurance they know how to work on pianos and and are not do it yourself'ers claiming to be a piano service Co..

If you were a customer, what do you wish you knew about your trade? Any inside secrets to share?

Professional service is the key. The first year your piano should receive the break in service of 4 tunings. No matter what make or type,all pianos require this service to compensate for the stretching of the new strings.Steinway is the only manufacturer I know of that provides this service prior to leaving the factory. After the first year, the piano should be tuned at least twice each year Add years of playing satisfaction. Follow these few, simple directions and you will keep your piano in superb condition. Contact Len Hess Piano Service regarding regular maintenance of your piano, or search www.pianoworld.com under "tuners" for your state or region.

What important information should buyers have thought through before seeking you out?

What is the Make and model of your Piano? When was it last tuned or serviced? How many times has your piano been tuned since you have owned it and if possible, before you owned it?How many hours of use weekly do you use the piano?Have you ever had anything other than tuning done to the piano?

Describe the most common types of jobs you do for your clients.⦁  


 The number 1 most common job comes from a neglected or un-serviced piano.

These are pianos which range from 10 to 50 years old which have not received any service since purchased.Factories recommend 4 tunings minimum in the 1st year to compensate for the stretching of the new strings.Some regulation is usually needed within the first 5 years depending on the amount of use, as the felt, leather,springs and other materials begin to seat and compact, allowing the factory diminsions to change which affects the touch tremendously.Most pianos interior parts are made of wood which is affected by changes in humidity and results in loose parts on the action from enduring 5-10 to 15 years and on of seasonal changes and fluctuations in humidity .The hammers become grooved and cut by the strings and require re-conditioning after a certain amount of use.If done at the proper intervals this can double or triple the life of the hammer. A thorough cleaning of the case and action is usually needed at this time.And finally the piano must be pulled back to slightly above concert pitch "A"440 and then a second fine tuning to "A" 440
