Piano Lessons- Music Theory Lessons

Robert,
What do reshaped hammers mean? I have seen this in some of the pianos you have on your site and am wondering as to what this means.
Sonja-

Good question! When hammers impact the strings, over time they develop deep grooves which are compacted felt. It creates a brittle tone. Hammers that are really worn can even flatten a bit. So, you can bring new life to hammers by reshaping them to the egg-shape which produces the best tone. Better than that, you get down to virgin felt which has a warmer sound. You can only reshape hammers so many times until you get to the wood – then you have to replace the hammers. These hammers have plenty of good felt to work with, so years down the line they can be reshaped again a number of times.

I may use this question and answer in my next video newsletter!

Robert,
Why isn’t the pin block made of metal? It does not need to transfer sound and metal would not have to be replaced.
– Kenneth

You ask a very good question. In fact, before the turn of the 20th century, Mason & Hamlin did indeed produce a limited number of upright and grand pianos that had metal, threaded pinblocks – not wood! These were referred to as “sidewinders” because the pins were parallel to the strings, not at right angles like in traditional pianos. They abandoned the design in a few short years and I am not aware of any other piano manufacturer utilizing metal pinblocks.

There are several benefits to wood pinblocks. First, the pins are threaded very finely. This allows for precise tuning. It is difficult to have metal machine screws with the geometry and strength to allow for the extreme fine tuning necessary in a piano. The fact is, there are over 20 tons of combined string tension in a piano. With a traditional pinblock when you restring the piano, you can use slightly larger pins and get excellent tuning stability. With a metal pinblock, the machine screws don’t allow for that possibility. Worse yet, if the metal breaks, it can be very difficult repairing. In traditional pianos with a wood pinblock, you can even replace the pinblock if necessary.

So, there are good reasons why nearly all pianos have had wood pinblocks for hundreds of years.

This question is simple to answer; yet very complicated when explored.

The quick answer is that a composition is a piece of music written for a specific instrument or group of instruments.

An arrangement is a piece of music originally written for one instrument or group of instruments and then re-written for a different instrument or group of instruments.

Why is this important?

When approaching a composition or an arrangement, there is a big difference in how you learn and play the music.

Generally speaking, when it comes to compositions you will probably want to learn what’s written and play the piece exactly as written; because every note matters.

When it comes to an arrangement, the approach is much different. Many times there are going to be multiple different arrangements of the same piece of music. One is not necessarily better than another, but there could be significant differences between them.

Usually, when it comes to arrangements, you are free to experiment a bit with the music. Now that’s not to say that you will want to alter what’s written drastically, but there are many times where an arrangement is written and is pretty much impossible to play. Especially when it comes to the piano, many times pieces of music created on other instruments and arranged for piano will include too many notes making it next to impossible to perform as written. In cases like this, it is up to you play what notes you feel represent the piece best.

When it comes to an arrangement, I believe you have a certain level of freedom to simplify it or even embellish it. There isn’t one way to adapt a piece of music – especially a whole symphony. I like to think of arrangements as more of a guide or a starting point.

Now some arrangements are intended to be played exactly as written – they are called transcriptions.

This question pops up all the time when it comes to performing. I’ve been asked many times if I could play Beethoven’s Fifth Symphony. I kindly respond by telling them that it’s a piece of music written for an entire orchestra and proceed to play Beethoven’s 5th Symphony by ear! Liszt wrote four hand arrangements of all the Beethoven Symphonies.

For beginning students I find it’s much better to have them practice compositions – there are even compositions from Bach, Mozart, Beethoven, and Schumann that are great for a beginning level. It’s much more beneficial to have them learning and playing something as written rather than playing a watered down version of an entire orchestral work.

Hi Robert,

I just watched one of your videos, which I enjoyed very much, and would like to ask a question if that’s ok.

I’m considering purchasing a used upright Steinway from 1969. It looks beautiful and sounds great, and the dealer (it seems to be a reputable store) assures me that it is in excellent condition. The parts are all original. I’m just concerned that a piano that old will fall apart on me in the next few years – and it isn’t cheap.

Do you have any thoughts on this? I suppose I should have a technician look at the piano.

Thanks!

You have probably heard about a pinblock and you might have wondered what it is. The pinblock is a fundamentally important part of the instrument. In fact, without a solid pinblock, you simply can’t tune your piano!

The big problem with the pinblock is that if it’s in bad condition and needs to be replaced you have only one option; rebuild the piano. You can learn about the process of rebuilding a piano in my video:

What’s the Difference between Rebuilding and Reconditioning a Piano?

I live in the mountains of Big Bear Lake, California where the relative humidity is often in the single digit to no more than 20% or 30%. What are the risks of keeping a piano in this type of climate? Do you have any suggestions to help with any potential damage caused by the climate?
– Kyle

You bring up an excellent point. Extreme dryness can also present major problems for pianos. The high desert in California, as well as parts of Arizona, can experience single digit humidity! The real danger is in drying out the soundboard. Cracks can develop, or hairline cracks which present no problem in most parts of the country can open up and cause buzzing. Other wood joints can also potentially suffer particularly if the piano was previously in a humid environment and gets moved to an extremely dry environment. So, a moderate humidity level is important for the longevity of pianos. You can mitigate the effects of weather in a number of ways which I described in my humidity video except in reverse.

– Buy and install a humidifier and make sure that you keep all the windows closed.

– Put a large, shallow pan of water underneath your piano.

– Install a Dampp-Chaser humidification system.

Be sure there are no heating vents blowing up at the soundboard of your piano (or behind an upright piano) no matter where you live. The key to providing the right environment for your piano is, if you would be comfortable sitting in the room where the piano is day and night, then your piano will probably be O.K. However, you may check the humidity level of your home and make adjustments if necessary with the previously described techniques.

I’m wondering if you have ever done a video on the performance practice of JS Bach ornaments. I know the specific ornaments like mordent and trill, etc but was wondering if you’ve weighed in on where and when to use them. My understanding is performers could add ornaments like spice, whenever they wished. It’s considered a type of improvisation in a sense. Please advise if you’ve made a video or have a link to someone else that has covered this online.

Thanks,
Dana

Ornamentation is a great subject for a video! It is also extremely challenging. The fact is, ideas about what is authentic Baroque ornamentation goes in and out of style through the ages. What was considered authentic practice today is different from what was considered appropriate 30 years ago, and different again earlier in the century. On top of that, there are varying ideas today. In my opinion, it’s impossible to really know for sure what the performance practices were hundreds of years ago. However, there are accepted norms in performance and deviating from them in a significant way raises attention to the ornamentation to a high degree. I still believe that there is a wide range of creative license in ornamentation, and you are right that it can be a form of improvisation.

Much Baroque music was improvised beyond just ornamentation. The trio sonata was often written in figured bass, a lead sheet type of form where the keyboard and continuo parts were realized by the performers, not scored note for note. So, there is a good reason to support the idea of freedom with ornamentation. The bottom line is to do what works and sounds musical. Different performers have unique ideas as to what that may be, but when the ornamentation supports the music, that is what is ultimately important. As for historical accuracy, we may never know for sure.

Here is a question about huge bass from a 158 Sauter.. Why and how can a super large high tension Base produce a better base than many 9 foot? It has more clarity and more vibrations and it is not duplex (per Ulrich Sauter)

One theory is that the low end has so much power that you bring into the tone short vibrations from the very heavy wires despite being padded.

What I found was an interesting tonal quality not found on my Mason and Hamlin upright. As you stated before sometimes the piano gets better as it gets older. I also recall your love of the grand. The piano has worked very well for our small and very hard working Chamber Music group..

Bruce

There are many mysteries to pianos. One really interesting fact is that even the same make and model of piano, new or from the same vintage can have dramatically different qualities. It’s important to remember that pianos produce their sound from wood and no two trees are alike! Add in the variance of human labor and those factors alone are a big deal. Now, take scale design. You would think that a 9-foot piano would have a bigger bass than a smaller piano. But as you can attest, that isn’t always the case. Think of some small speaker systems that utilize creative technologies for getting huge bass out of a relatively small package. There are so many variables in design as well as in the preparation of a piano. Ultimately, your ears tell the whole story.

This is a very important subject; not just for music but for life itself.

When Thomas Edison was trying to create the light bulb he went through many attempts before he actually got it right. In fact, legend has it that one of his experiments actually ended up in the complete destruction of his lab – it literally blew up!

The story goes that Edison’s assistant asked him if he felt defeated; Edison responded by saying something to the effect of: “now I know yet another way NOT to make the light bulb.”

By being persistent and not letting failure get into the way, Edison was able to achieve more than anyone could have imagined. He used failure simply as a stepping stone to success; he used those negative experiences as positive learning experiences.

Edison is not the only historical figure to face failure. In fact, many of the world’s most successful people have faced enormous challenges and failure until they finally hit their mark.

The same theory rings very true for musical performances. For example, when I go to student recitals and I hear someone play through a piece without any problems I can’t help but be impressed. But what impresses me, even more, is how they handle mistakes.

Inevitably something will go terribly wrong during a performance. Whether it’s a wrong note, a memory slip, no matter the cause, mistakes do (and will) happen. Watching these students recover from something like this and not let it affect them is very impressive. One small mistake will not ruin a performance and it’s very important to remember that.

If you miss a note in a performance and you keep going, chances are nobody will ever know. However, if you make a mistake and then go back and try to correct it; everyone will know you messed up (no matter how schooled they are in music).

Every great performer won’t worry about every little mistake. Sure they might miss a note, start to rush, or play something completely wrong; none of it matters. What matters most is the performance itself and the energy and passion that comes from the performer. It’s never about perfection; it’s about emotion.

Remember that your audience is there to enjoy themselves. Learn from your mistakes but don’t let them defeat you.

You might have heard the term scale design used before and wondered exactly what it is. Well, the answer has a number of parts and can actually become fairly complex. I’ll do my best to explain exactly what it means and how you can spot the differences on your piano and others.

Scale design is something that is unique to each piano. It involves not only one aspect but the entire design of a piano in regards to how it produces tone. If you look inside a piano, you will notice that there are varying lengths of strings; the treble strings are shortest and then gradually get longer as you progress down to the bass strings.

Each piano actually has a slightly different geometry in how these strings get longer. Also, the strings have different diameters – the strings at the treble register are the thinnest and the strings along the bass register are the thickest. Some pianos will actually use what is called a high tension scale – which means that the strings are thicker but will have to be pulled with more tension in order to create the same pitch. Other pianos will have a low tension scale which is basically the opposite of high tension – the strings are thinner and require less tension. Is one better than the other? Not necessarily – these are just two different methods of achieving the desired tone.

This is not all when it comes to scale design; this is just the beginning!

Once you progress to the lower register of the piano you have copper wound strings. Where the copper wound strings begin is again part of the scale design of a piano. Believe it or not, the difference in where these copper strings start is different not only with different brands of pianos but in the different models of one manufacturer. For example, on the Steinway M I am using in this video, the copper strings start slightly before the register break.

What is a register break? This brings us to another important aspect of scale design. You probably notice that on your piano there is a section in which cross stringing occurs – where strings are crossed over one another; this happens in the lower register. The point at which the strings begin to cross over is called the register break.

Believe it or not, even the winding of the strings has something to do with scale design. Sometimes the copper wound strings start with the double strings and in the lower register become single wound. Other times there are even triple wound strings in the upper bass area as in my Baldwin SD-10 Concert Grand.

Another aspect of scaling is where the string is actually hit by the hammer. If you look at the action of your piano you will notice that the hammers strike the strings at specific points. This is done very deliberately to produce a certain tone. The exact point at which the strings are hit has a dramatic effect upon piano tone. If you have ever played guitar, you notice the different tones you get when plucking strings at different points from the bridge. It is the same with pianos.

There are other technologies when it comes to scale design as well. The non-speaking part of the string – the part beyond where the hammer strikes – can also have something to do with scale design. Some pianos have what is called duplex scaling. This allows the strings to resonate freely without muting them at these points – producing musically useful overtones. Other pianos have felt that will dampen the sound at these points because they are not designed to have them produce an additional tone. Is one better than the other? Again, not necessarily; while duplex scaling can enhance tone, it is not the only way that piano designers can achieve great results.

Another aspect of scale design is where the bridges are placed along the soundboard. This is again something that is very important in producing a certain tone in a piano. In fact, in the earlier pianos before cross stringing emerged, the bridges were placed along the edge of the soundboard. Modern pianos with cross stringing achieve better tone by having the bridges more centrally located on the soundboard.

The bottom line when it comes to scale design is what it sounds like. Sometimes pianos designed by computers are “perfect” in the mathematical sense but don’t necessarily offer beauty or warmth of tone that the slight imperfections may provide. This is truly part science and part art, but what’s most important is how the piano sounds and feels to you.

Welcome to my first in a multi-part series of videos about what makes each major piano brand unique. Every major piano company has something that separates them from their competition: whether it is Mason & Hamlin’s Tension Resonator System or the Steinway Accelerated Action, many major piano brands will have some sort of unique or patented design element that their competition doesn’t employ.

This might sound silly but this is actually a very complex question.

When I was growing up, my father Mortin Estrin was a Baldwin artist. When he was selecting new pianos for performances and recordings, we used to go into the Baldwin artist showroom in New York City and he would play all the pianos and choose the one he liked the best. Back then, whenever he would encounter a restored piano he would scoff at them and couldn’t see any value in them. For a large part of my life, I grew up with a similar mindset.

But now things are different for me; I sell restored pianos. So what changed? Well, pretty much everything when it comes to pianos. Back when I was growing up we had Baldwin, Steinway, Mason & Hamlin, Knabe, Sohmer, Chickering, and dozens of more piano brands still producing new pianos in the United States. Today, we only have 3 piano companies left making pianos in the US and the rest are mostly made in huge Asian factories at a fraction of the cost and quality of the handmade pianos of yesterday.

There are still some pianos being made today in America and elsewhere that maintain a very high quality – but unfortunately, they come with a very high price tag. However, the vast majority of new pianos are nowhere up to the standard of the handmade pianos.

At the turn of the 20th century, there were over 1800 companies producing pianos in the United States! Sure, we still remember some of the big names, but with hundreds of companies competing for the top spot, there were plenty of phenomenally high-quality pianos being produced during that time period. Every company had to compete against each other and while everyone was at the peak of production, the quality was at an extremely high level; it had to be. However, the vast majority of pianos ever produced in the US are very old now.

Right before World War II, there were still over 300 piano companies in the United States. They were producing lots of high-quality pianos but even this was a long time ago. Many of these instruments have not stood the test of time – whether they weren’t maintained properly, succumbed to the elements of nature, or just wore out.

Some old pianos have huge potential to be great. The craftsmanship and level of work were outstanding. However, a lot of their potential lies in the life that these pianos have had. How well have they been preserved? And how much work has been done to make them play like a new piano?

In a perfect world where money is no object, you could buy a brand new Hamburg Steinway or Shigeru Kawaii or other top brand and have a wonderful piano. For most people, however, if they are looking for a top tier piano they will most likely consider a vintage instrument that has been meticulously restored.

There is a wide range of tones possible with many of these vintage pianos. Even the old Mason & Hamlins and Steinways have a different quality than the ones being produced today. They have slight differences in the methodology of production. There were also countless, skilled workers from what was a huge industry. Some people think the quality and aging of the woods produces a richer tone like a Stradivarius violin.

From my experience, I have seen quite a bit of magic produced out of the great, vintage pianos. There is a difference in quality and tone that is rare on newer pianos. However, the question of whether or not they are better comes down to the individual pianos. You simply can’t compare the quality of Asian production pianos and handmade pianos. However, this is not to say that every handmade piano is better. Really the bottom line comes down to personal preference. Some people, particularly in rock and pop actually prefer the more strident tones produced by factory pianos today – it is a sound many people have become accustomed to.
