 The Melodious  &  The Harmonic

Basic maintenance is the key of the life for your piano. Yearly tuning will save you money in tuning and repair costs.  A yearly tuning keeps the pitch stablized allowing the tuner to spend less time adjusting the strings, which in turn, helps save you from spending more tuning time to put it right. As the tuning  deteriorates over time, the piano requires extra time to bring it back into good harmony. The tuning adjustments become grosser rather then finer so the piano does not hold its tune like it should requiring it to be tuned sooner then expected. Pianos do not hold their tune forever and they need your periodic attention to keep them performing well. Over time, the piano wears down; yes, even if not played. Pianos need cleaning as they are great dust collectors, the parts can stick, break, as well as measurements changing between the parts, which happens because of playing, Over time the piano requires regulation work to adjust for this deterioration. These things can be remedied while having a yearly maintenance routine.



There is nothing sweeter then a beautiful melody and the sweet harmonies that accompany it. What kind of world would this be without music? We all know the answer, so we do our best, to bring sweetness into the world with whatever our skill specialties may be.       This is how I do it.

Understanding the theory, mechanics, and physics of how a piano should function and sound, then applying it to the piano, is my way of bringing enjoyment to others thru my work.  In turn, their playing brings enjoyment to their family and friends and spreads love through the world one piano at a time.

My love for pianos stems from the  beauty that is inherent in this magnificent instrument. Read my inspirational verse on the "about us " page.

Tuning your piano to this frequency, "A-440 " , will maintain the required string tension on the piano making the yearly tuning less costly as it reduces the time needed for tuning. Also, it enables the piano to hold its tune for longer periods of time which is a big benefit for the player as well as the caregiver.

Cleaning the action benefits the player because it keeps the moving parts of the piano from freezing or becoming sluggish, in other words, it won't have the response needed to allow for good finger technique and dexterity which is needed to transfer emotions from the keys to the ears.
Many pianos are in need of repairs due to lack of attention over the years. There are thousands and thousands of parts in a piano and any one of them can fail in one way or another as a direct result of playing or not playing. Maintenance is so important for the well being of your instrument which is why all piano manufactures suggest, at least, a yearly tuning because at this time the instrument will be examined as well as tuned.
Playing the piano naturally produces wear and tear on the parts. Many pianos are so worn down the parts need to be corrected or changed out. Pianos are constructed of wood, felt, and metal. Wood can stain, warp, rot, and be bug eaten, calling for refinishing, refurbishing, or even replacing. The felts can be bug eaten as well from moths, mice. Etc. but the felt will wear down just from normal usage, causing tolerances between the parts to be compromised making piano playing not much fun for the player.
Regulations are the procedures for restoring the correct measurements established by the factory during manufacturing. Regulation and refurbishing, converts an old used piano into a great playing and sounding piano again.
Refinishing of course will take old looking wood that's chipped, stained, sun damaged, or a finish that's cracked or crackled with age; removing the old finish, cleaning and refurbishing the wood, and applying a new finish, thus restoring the case to its original beauty again.

The tonal qualities of pianos are a result of the size and scale of the instrument, the soundboard size and the woods used it its manufacture. The hammers that strike the strings are the main action parts that are easily accessible to actually change the quality of sound, or, its voice.  Hammers can be softened, hardened, fluffed, steamed, reshaped, chemically treated, or changed altogether, which all falls into the category of "voicing," which is a sub set of regulation. Hammer heads are made of felt and they take quite a punishment. Over time, hammers are continually pounded into metal wire strings causing eventual compacting and hardening of the felt heads, wearing, tearing, and mis-alignment injuring the tonal output of its sound.  Fortunately, a good technician can prolong and enliven the hammers by using these diverse remedies mentioned above.

The piano is quite an instrument, and as such, it is deserving to be maintained and respected or it will deteriorate. The further it deteriorates the more it costs to bring it back to life. In many cases a restoration is in order. Restoring a piano to its original glory is quite a task but certainly worth doing to certain pianos. Some people do it because it's a family heirloom; others, because they love their instrument and would rather restore then to buy another new or used.
There are many reasons to buy, to sell, to repair, to refurbish, to refinish, to rebuild, or to restore; and each person, of course, has their own choice and reason. I can provide good advice and years of experience in these matters and hopefully help you have the right outcome.
