The Perfect Touch

The hunt to find the piano with a perfect touch would be a very tough assignment. On a 10 point checklist of qualities required for consideration, very few pianos would achieve 10 out of 10.

Though wonderful specimens of the piano maker's art, even expensive new pianos, are often short on the magic that sparkles when the action and keys supply the player with the wings of creative inspiration - allowing flight to that mysterious zone where, the player is released from the confines of unsatisfactory playability, and enjoys the timeless pleasure of music making purity. This zone is home to the perfect touch. Playability fulfilled!

A tuner/technician's experience will agree that perfection in a piano is almost unheard of! My old boss, when I was an apprentice, often used to say, "Pianos are imperfect instruments!" - of course, back in the 1970s, he was right - the pianos of the time were generally very poor and always, had issues. I think he got tired of having to find new things to say to customers who rightly felt disappointed with their purchases.

Surely today, pianos must be somewhat closer to the ideals of the piano designer's blueprint! Throwing money at the problem is not always a complete solution - indeed, unless the those undertaking the challenge of sorting it out, know exactly what they are doing, the finished piano might still only be an expensive disappointment.

We, in the trade must strive for excellence and then, go the extra mile, make an art of the job, sprinkle with gold dust and unlock the wonders of a well regulated action and give the 'Perfect Touch' within, the chance to inspire further generations of keen pianists!

Old Piano Tuning Tools

Over the years, a tuner will meet older tuners who learned their trade maybe a generation or two ago. Invariably, these old guys - certainly in the UK they are almost always guys - are full of stories, and often a great source of tips and ways of doing the routine and time-consuming jobs of restoring a piano.

When they retire - they still hang on to their tuning kit for as long as possible! Occasionally younger tuners inherit these old tools and they become memories of the person who used them for so long. Really, some of the tools belong in a museum but it is always fascinating to hold these relics of former times. 

Here are some of the old tools that have been passed on to me: 
A 'T' Hammer and a wooden 'papps-type' tuning wedge. 

A few regulating tools - key spacers, set-off regulator, a not-quite-so-old check-bender and spoon-bender.
Tuning lever
This very old tuning lever I now use as part of my own kit - my normal lever has detachable heads which is perfect for most pianos but I found that the head for smaller tuning pins was not small enough for some of the old pianos I tune from time to time. One day I thought I'd look through the box of old tuning tools and discovered this little wonder! It has a small star head and is the perfect lever for these old pianos with tiny tuning pins. After a good clean and varnishing the handle, it is now a valuable part of my own kit!

New Pianos

Surely, buying a new piano should to be straightforward enough, shouldn't it? As there are not so many piano shops around, if you wish to compare prices or try pianos in more than one shop, your hunt for a new piano will mean a good deal of travelling.

A piano can seem perfect in the shop, but at home in your music room, the sound hardens into a strident, in-your-face tone which is difficult to control and hard on the ears. Second thoughts, regret and disappointment are not easy to overcome when you have bought an expensive piano. Surely a piano costing so much should be satisfactory from Day One!  

It is not uncommon, as a technician, to be called in to deal with a brand new, expensive and newly-delivered piano that is terribly out of tune and/or the action is very heavy and difficult to play. Promises that the action would loosen up or the tone would mellow after being played for a while, prove to be disappointingly empty. The owner is very unhappy - and understandibly cross that there is a problem at all!

These issues can all be sorted but not in about 10 minutes. It is not rare to find a brand new piano which is so heavy to play the action needs re-centring. Frequently one finds keys that are sluggish, hammer-felts that are as hard as nails, notes going wildly out of tune or pedals that squeak every time they are pressed down. 

I have a great deal of sympathy for New-Piano-Buyers who feel so let down by their new piano. Piano brochures - without exception, make bold claims about the quality and care of manufacture. But sadly, too often, modern pianos never quite live up to expectations. 

In an ideal world, all pianos would be ready and 'match fit' long before it is delivered to the home of an excited pianist who has invested their hard-earned money in their dream piano. 

Perhaps 50 - 60% of new piano owners would say they are totally satisfied with their purchase. Possibly, the tuner/technician's satisfaction rate would be rather less, but the reality is that if brochures were written by the purchaser there would be less use of extravagant superlatives to describe the piano. 

Buyers should insist on standards that match the price they pay for a piano. One expects the quality of a cheap piano to match its low price. Equally, the quality of an expensive piano ought to be at least as high as the price - certainly, no lower!

Piano Repairs

Repairing a piano will involve considerable expense - some of the new parts are relatively inexpensive but, for example, if you wanted a set of new hammer-heads fitted, suddenly the price for the work soon begins to look like a serious amount of money. Sentimental reasons may push aside fears of overspending but if, after parting with a whole load of cash, the piano is still an untuneful and uninspiring instrument then the cost to honour a memory will seem to have missed the mark.
 
Of course, opinions will vary from technician to technician, but here are some guidelines for the careful piano owner who wishes to avoid overspending on their piano:
  1. Assuming the piano to be repaired is an average, mid-range quality, regularly used and up to pitch. ...in this case there is scope for fairly extensive repair - some refelting, replacing of springs etc. but unless it is a family heirloom, do not have it completely rebuilt.
  2. If the piano to be repaired is less than an average piano, straight-strung, overdamped, difficult to keep in tune, has numerous broken parts. ... in this case, spend any money upgrading the piano. If funds really don't stretch that far, find a tuner who will help you keep it going without charging you the earth. Any serious money spent on these pianos is money down the drain!
  3. If the piano to be repaired is a top quality, named piano, total rebuilding, though expensive is not out of place. If the existing condition of the piano is tired and worn out, sometimes rebuilding is the only way to restore its sparkle. However, on a personal note, the older the piano, take extra care. ...in my opinion, only this kind of piano stands as a sensible candidate for the cost of rebuilding!
Are there exceptions to the rule?  

As ever, yes! Occasionally I meet with a piano which does not neatly fit into the categories mentioned above, but if it has enough of that difficult-to-define piano charm to set it apart from the ordinary, then go ahead. The last such piano for me was a very fine old French piano. Rare, and well-preserved, it did not need a complete rebuild. New hammerheads, new damper felts, kept the original strings and the result? All things considered, a good value-for-money option for the owners.

Replacing Hammer Heads

Replacing Piano hammers is not a quickly done job. It can appear easy and straightforward to take off the old hammers and and replace them with new ones, but like everything else to do with a piano action, unless the job is done neatly and evenly, the end result will be a poorly sounding piano and a miserable technician! Not what you want after an expensive and time-consuming project.

The cost of a set of piano hammers is more than most people would like to spend on an interesting experiment. If the experiment goes wrong, you will have to spend more money get someone to fix it. A set of new hammer heads must match the old ones. A 5mm difference here or a slight change of angle there, will only guarantee you yet more hassle and grief to get the piano to play properly when you've done all the work.

The first job is to dismantle the action. (The job is similar for a grand piano but for the sake of clarity, the instructions here are for an upright piano.) Disconnecting tapes and taking off the levers will give good access to the hammer flange screws. Take the hammers off, place them on a tray and number them – just in case they, for some reason, get mixed up. Most new hammer heads come already bored - if your set is not already bored, you have yet another 'mountain' to climb. The secret of success in action work is in the precision and care with which it is carried out.  
Removing the old hammer heads from the shanks is done one at a time, using a special tool called a shank extractor. Some technicians like to leave guide hammers on the action so that the new hammers can be lined up to keep the same line as the old ones. Other technicians prefer to take exact measurements from the each hammer as it is being dealt with. If guide hammers are used, it is important to fit the right hammer head to these guide hammers. 
With the old head removed, the shank cleaned of old glue, (any broken shanks replaced) it is quite simple to glue the new hammer head onto the shank. It helps if the fit is firm and snug without being too tight. If the fit is on the tight side, take care not to twist the shank when fitting the new hammer head. Brittle, old shanks break easily. 
When ready, refit the hammers back onto the action frame. The ‘noses’ of the new hammers heads should be in a nice straight line. There is a number of ways of replacing hammer heads, all of them are perfectly acceptable if done well. Fitting the hammer heads to new pianos is done in seconds, but away from the factory, dealing with replacement parts it is a much slower process. 

Putting the action back into the piano is the start of another set of very technical adjustments to ensure the proper working of the piano action.
Do not underestimate what is involved in getting a piano to work well. A change to any part in the fabric of the mechanism has a knock-on effect on the function of the action, how the piano plays, and how it sounds. 

If only replacing piano hammers were like replacing a failed light bulb! Then, any careful amateur could do it. But the reality is that replacing hammer heads is not really a job for the amateur - at least not without professional advice and help. 

At best, this article can only be an introduction to the very basics of the job. So please, be careful!

Straight Talk to Piano Owners

Pianos are to be cherished and enjoyed. Pianos give a family home a musical focus and a source of great pleasure. What can possibly go wrong?

When a tuner or technician, reporting on a much loved family heirloom gets to 'bottom line' as it were, sadly, too often there is not a lot of good news.

Piano owners hope that an old piano can be made good for as little as £50. If only this were possible! Frequently asked questions about the potential of a given piano, will quite understandably, raise the issue of cost. 
One piano was described as having been attacked by moth! "How much to fix this?" 
Another has a number of notes that stick - making the piano virtually unplayable! "How much to fix this?" 
"My piano has a number of broken strings! How much to fix these?"

The grim reality with all these problems is that none of them are properly sorted without spending a considerable amount of money. It is not easy to communicate that a piano is beyond viable hope.

Spending large amounts of money is advisable only on what is already a good quality, named piano. Even then, the money spent will be more than the eventual value of the refurbished piano. If the piano has a particular family history - precious memories of loved ones no longer present - then the cost becomes irrelevant and the project becomes one of preserving a cherished item of a family's history. This is priceless!

The development of the piano was largely complete by 1900. Since then, focus of further development has been more on materials and methods of construction. 

The use of plastic in the action and keys became quite widespread in the UK during the 1970s. These pianos cannot be described as being old but have serious problems. It is very difficult for the owners of these very poor pianos to understand why their beautiful little 'modern' piano should be written off so glibly, or given a value so low that they have to give it away. Alas, these pianos are simply beyond sensible repair. 

Thankfully, the better quality pianos of this period stuck to more traditional materials and consequently they still offer the piano owner great service and very good value for money. Repairs if they are needed, might seem expensive but should rejuvenate all the fine pianistic ideals of the piano maker's original creative flair.

The piano world is a confusing and unforgiving place. Buyer, beware! Before being persuaded to part with lots of money for a purchase or a repair, try to get quality, informed and impartial help. 

Pianos are to be cherished and enjoyed, they are not supposed to be a source of regret and dissatisfaction.

Piano Action and Keys

The piano action and keys are the great link between the pianist and the music heard by the listener. This sophisticated mechanism is capable of a vast range of dynamics and expression - it is a masterpiece of engineering. Every one of the eighty-eight notes has it’s own key, it’s own hammer, it’s own strings and it’s own set of levers. 
The movement created by depressing the key, is delivered to the hammer via a series of levers. The hammer strikes the string - thus generating the audible musical sound of the chosen note.

The design of the piano action has altered very little over the last 120 years or so, which means that the basic piano action design was perfected long before the computer was even thought of - let alone being brought in to help. Those who devoted themselves to the task of developing the piano action, used sheer inventiveness and dedication to get their ideas to work.


A grand piano action

A quote from a book about piano action design by Walter Pfeiffer: “...the action is that much closer to perfection the less the player is aware of it” 

The modern piano has the potential to achieve this lofty state of function. Pianists, not having to worry about the technical aspects of the mechanism, are free to give themselves to making music. 

Technicians strive to get the very best out of a given piano. With their detailed understanding of the workings of the action, the piano becomes far more than just a machine. The less the player is aware of the mechanism, the more able is the artist to explore that mysterious zone only a musician understands - and thus the piano is to closer to perfection.
