What is Piano Regulation, Voicing, and Fine Tuning?

This question encompasses quite a bit of information, but it has value in presenting it all in one video – as these topics have a lot to do with one another. They are all essential when it comes to getting the most out of your piano and making sure it plays its best. Each one of these subjects can be incredibly detailed, and I may create more detailed videos and articles for each one of them – but for now, I will provide an overview of all three!

First, we will deal with Regulation. Regulation encompasses the myriad adjustments on the action which is the entire mechanism from the key to the hammer and dampers. Each key in the action has about 100 parts. There are approximately 8 different adjustments for each key: from key height, key depth when depressed, let-off of the hammer after it’s struck, to other details of hammer movement, and other adjustments affecting repetition, power and more.

The basic explanation of regulation is getting an evenness of touch for all of the keys on the piano. In other words, all 88 keys should have an equal touch when playing – no key should be harder or softer than another; no key should be higher or lower than another; the response must be identical for all keys.

When it comes to Voicing, it’s the same principle in keeping a consistent state for all notes. However, voicing deals with the tone of the piano, not the mechanics. Every key should have a consistent sound from one another. If the touch is the same but specific notes are brighter or more mellow in tone, it is impossible to get a smooth musical line since some notes will be out of place in the melody, either not matching volume, or tonally different in some way.

How is voicing achieved? Through working the hammers to get a consistent volume and tone from all keys. The felt on the hammers needs to be accomplished to get consistent tone on all notes. Several things affect the hammers including the shape, how it impacts the strings, and the hardness.

There is a tremendous amount of work that goes into voicing a piano. For example, if the hammers on some notes are too hard they will need to be needled; if they are too soft, they will need to be treated with chemicals, typically lacquer. This treatment will need to be performed on each hammer, and the response of each string within each note should also be uniform in tone.

Last we have Fine Tuning. A piano can be tuned, but there is something referred to as concert tuning. A concert tuning encompasses not only making sure the tuning is pure but making sure it will stay in tune! It’s not nearly as easy as it sounds. Fine tuning will require a technician to pound on the keys and make sure the piano won’t go out of tune even with a tremendous amount of force of a concert pianist playing virtuoso music.

I’ve also seen tuners who will fine tune a piano and then close everything up, hold down the sustain pedal, and then hit all the keys with their arms to excite the soundboard. The hope is that the strings can be reset securely to hold during the performance.

The truth is, there is no end to how far you can go with a piano. You can continue to make finer and finer adjustments and never really reach a real level of perfection. Like one definition of infinity, you can get halfway closer to perfection again and again with diminishing returns on time spent.

If you have ever had the opportunity to play a piano after it has been voiced, regulated, and fine-tuned, you will never want to play anything else! It really is that big a difference on a great piano.

Piano Questions: Major and Minor Tonality – Pianos in Cold Weather

Hi Robert,

Where are the steps and half steps in the major scale?

I mean, why is the half step between the 3rd and 4th notes (E and F) and not between 4th and 5th, or 5ht and 6th…?

Ricardo

Ricardo,

This is a great question. In fact, centuries ago the half steps were found in different places. These were called modes. Basically, if you start a scale on different notes, the half-steps will occur in different places. Think of playing the white keys starting on D and ending on D instead of going from C to C. Instead of having half-steps between the 3rd-4th and 7th-8th notes, as in a major scale, they would be between the 2nd-3rd and 6th-7th notes creating what is called the Dorian mode. You can start modes on any scale degree creating different modes.

Eventually, the major/minor tonality caught on. One reason for this is the power of the raised 7th. While the minor scale is actually a version of the Aeolian mode (which are the notes starting on the 6th note of the major scale) it is most often found in 2 altered forms, the harmonic minor (which has a raised 7th) and the melodic minor (which has a raised 6th and 7th). What is so powerful about major/minor tonality is that some tones are stronger than others. There are active tones which must resolve to restive tones. Just try playing a slow major scale ascending and stop on the 7th note. You will feel incredibly compelled to play the last note. That is the power of tonality!

Hi Robert;
I have a 7 foot Steinway piano. During these terribly cold months, it has been going out of tune.

I have a damp chaser. Would a microfiber blanket be safe to cover the INSIDE of the piano?

Also, what temperature should my gas heater be kept at night?

please let me know. I read your e-mails; they are very helpful.

Thanks,
Mary

Mary,

Your piano will keep its tuning best in a stable environment. The rule of thumb is if the piano is sitting in a place you would be comfortable sitting day and night, your piano will probably be fine. A string covering blanket could be helpful. However, the underside of the soundboard will still be exposed. Fluctuations of temperature from the 60’s to 70’s shouldn’t present problems. Avoid direct sunlight on the soundboard. This can change the tuning rapidly.

Can You Play the Piano Too Hard? Playing the Piano Too Hard

Can You Play the Piano Too Hard?

This is a very common question I get all the time. However, it’s mostly a concern for parents with young children who are worried about the damage that might be done when their children bang on the keys of the piano. I find it very funny actually – as I see this quite a bit – where a young child will go to the piano and start banging on the keys and the parents tell them, “don’t do that; you’re going to break the piano!”

The truth is your kids won’t be able to harm your piano simply by playing it with their fingers. Now, it’s a complete thing altogether if they drop something heavy or sharp onto the keys – that can cause some serious damage. But just playing the piano with their fingers is little – to pretty much zero – risk of any sort of damage.

A concert pianist playing Liszt or Chopin or other composers will play the piano with such force that even if a child hitting the keys with their fists they would never be able to equal the power of the pianist. Pianos are designed to withstand a tremendous amount of force.

Now, the question of whether or not you can play the piano too hard is a bit more involved. When it comes to sound quality, it is possible to play the piano too hard – to the point where the sound quality is degraded. For example, a concert level Steinway or Baldwin or other top-tier pianos (voiced on the mellow side) would be able to withstand an extreme level of playing and produce a very nice and clear sound. However, a cheaper piano – or one not regulated properly with harder hammers – would not be able to withstand the same amount of force without sacrificing some of the quality of the sound; you will most likely get distorted tones.

The biggest factors when it comes to sound quality and playing the piano too loud are the quality of the instrument and the hardness of the hammers (or how the piano is voiced). A piano that is voiced bright will have to be played a little more gently. I find this to be common when it comes to European pianos. They tend to be voiced a little more on the bright side and it is easier to overplay them.

The best guide is to simply use your ears. There might be a Steinway that is voiced too bright and there might be a Bechstein that is voiced on the lower end – it’s all up to your ears and you as the player to tell what is working and what isn’t when it comes to sound.

Is there any indication that you can be playing the piano too loud? Other than looking around the room and seeing if anyone is covering their ears there is the possibility that room acoustics can play a very important role in the loudness of the piano.

This took me a very long time to learn properly but the room in which a piano is placed has a lot to do with how it sounds. There is a possibility of an undersized piano for a room – where it will sound too quiet and the pianist will play the instrument harder to get more sound – and there is a possibility of the piano being too big for a room as well – leading to sound degradation and unhappy listeners. This truly is a topic for another video, but again just listen and make your own judgment as to whether or not the sound quality is ok.

PIANO QUESTIONS: Becoming a Better Player – Sticking Keys

Hi Robert

I’ve been watching your tutorials on YouTube and found them inspirational, I too wish to one day play the piano professionally. I’ve just got a keyboard atm because my home can’t support a piano.

What do you suggest I practice on a daily basis to become better and more fluent in music? Do I need a tutor? I’m just really unsure on those topics and it worries me.

Thanks,

– Varis

I wish you great success in music! If you want to work as a pianist, there are many different possibilities. So, the preparation necessary will be determined by the specific goal you have. In any event, having great training is essential for the vast majority of people who make careers in music. I suggest immersing yourself in music and piano and developing some sort of vision as to what you want for yourself. Then you can work backward from that point. You may realize that having a piano and lessons are important facets to assure progress depending upon the nature of the career you aspire to.

All the best-

Hi Robert,

I asked about the Grotrian because there is one I’m considering in Chicago, a 2010 Charis model (6’10”), pre-owned. But I’m just not sure about the piano. It has a gorgeous sound, but it’s badly regulated, with uneven action, problems with p-pp playing in some registers, many keys remain sticking up when you push them up. I’m concerned about what happened to that piano when it was privately owned(in Colorado).

Is this normal for a new piano? Any guess on what happened to it?

Could you recommend a reputable tech in Chicago? Thank you again.

Brian

I would be very cautious about the Grotrian you are considering. It is not normal for an almost new piano to have these sorts of problems. It calls into question the history of the instrument. If it is being liquidated at a fire sale price, it could be worth the risk. Please let me know what they are asking for the piano. It would be wise to get a technician to look over the instrument to make sure there isn’t something severely wrong with it.

Best wishes-

Living Piano: Journey Through Time: Historic Concert Experience

Living Pianos: Classic Restored Pianos grew out of a live show I have been performing for a number of years, Living Piano: Journey Through Time: Historic Concert Experience.

I noticed that at so many of the concerts I performed that I was the youngster in the room! I felt their should be a way to bring young people into the fold. That is when I had the idea for Living Piano. In music conservatory, I majored in piano and French horn! In fact, through much of my career I was focused on music technology owning a recording studio producing music for film and video and presenting my Keyboard Showcase performance offering audiences a glimpse into how computers had impacted music.

Eventually the technology grew to the point where the live performance became almost irrelevant as looped based composition/music production replaced performing. So, I went back to my roots as a performer and acquired historical instruments, learned how to play them and began bringing them to audiences at universities, colleges, art centers, museums and even a Living Piano cruise!

Today I perform a wide range of musical events including Living Piano: Journey Through Time: Historic Concert Experience in which I bring young prodigy performers I work with in period costumes of Mozart and Liszt. It ceases to amaze me the universal appeal of the story of the development of the piano. I have performed Living Piano for audiences of all ages and offer my program in a variety of settings including fund-raising events for worthwhile causes including schools and arts organizations facing the challenge of acquiring concert level pianos.

If you are interested in exploring the possibility of having Living Piano: Historic Concert Experience hosted for your group or organization, please contact me, Robert Estrin at:

What is the MOST Important Part of a Piano?

There is really no ONE part of a piano that is more important than all of the others; however, there are TWO pieces of a piano that are absolutely fundamental to the health of the instrument.

The first piece is the cast iron plate. Structurally, the plate needs to be solid for the health of the instrument. There are over 20 tons of string tension exerted onto the plate – its integrity is essential for the proper function of a piano.

piano plate

Can piano plates crack? The answer is yes. It is very rare to find a cracked plate, however, there are certain models and designs with thin sections of the plate which are prone to cracking. Also, a piano that has been dropped may suffer cracks in the plate.

If you are looking to buy a piano that has a cracked plate, it can be a deal breaker. It can be like buying a house with a crack in the foundation. It’s usually fatal unless the crack is on the perimeter of the plate and is self-contained.

There is another part of the piano that in some ways is even more important because it gives the piano its unique personality – the soundboard of a piano. The soundboard is such an important part of the piano that in parts of Europe it is illegal to put the name of the original piano manufacturer on the front of a piano with a replaced soundboard! The soundboard truly is the lifeblood of the instrument. Nearly all of the sound of a piano is produced from this thin piece of wood that is built into the rim of the piano.

What should you check for in the soundboard to make sure it’s in good condition? Well, unlike the plate, cracks are not necessarily deal breakers. Cracks in soundboards are a normal part of the aging process in most climates. About the only way to fix a soundboard with severe problems is by rebuilding the piano which entails removing the strings and the plate. This gives an opportunity to rework the belly of the piano. Generally, the soundboard is gently heated for a couple of days (usually with some 100 watt light bulbs). Then the technician will place small shims of wood into the cracks, glue, sand and refinish the entire soundboard. Most cracks can be repaired using this technique. However, there are other problems facing soundboards which are more serious. If the soundboard warps and the ribs become detached, they can cause buzzing and must be fixed. If the warping is too severe and multiple, large cracks are present, it may be beyond repair. Replacing a soundboard is very expensive and the piano will have a completely new character of sound.

One aspect of a soundboard essential for a powerful, sustaining tone is called crown. The soundboard is built into the rim of the piano under pressure causing a slight, upward arching. This is called crown which is essential for proper piano tone. While some people attempt to run a string underneath the soundboard to measure crown, the ultimate test is the tone of the piano. Usually if crown is lacking, the treble notes will not last very long. This is very disappointing since it becomes nearly impossible to get a singing melody out of the instrument.

These two parts – the plate and the soundboard of a piano – are certainly important parts of the piano – but the instrument can be compromised by many other factors.
