Welcome to LivingPianos.com, I’m Robert Estrin. The subject today is about how piano is a flawed instrument. Now, I love the piano. It’s incredibly expressive. It’s one of the greatest instruments of all time. So I’m not complaining about the piano in any way, shape, or form. But it’s important to understand the limitations of the piano. The piano is a tempered instrument, meaning it can play in all keys. So, every single interval on the piano, with the exception of the octaves, are out of tune.
There are no two notes you can play on the piano other than the octaves that are in tune with one another.
So when you play a perfect fifth, it is not perfectly in tune. How can this be? Well, years and years ago, keyboard instruments were tuned for the specific key they were playing. String players, singers, and other instrumentalists will naturally adjust their tuning to make every interval pure. It’s just not mathematically possible to do that on the piano to be able to play in all keys. Every interval is a little bit out of tune, but they’re all equally out of tune in all keys. That is what is meant by tempered tuning. And we’re so used to it now that it sounds in tune to us as long as the piano is in tune. It’s important to understand this fact.
I recently listened to a piano roll of Gustav Mahler playing his Fifth Symphony, the first movement. If you’re familiar with any Mahler symphonies you know that these are incredibly complex orchestrations. Piano rolls are actual performances of the great composers and pianists from years ago before audio recording existed. A lot of times they don’t sound quite right, because the playback instrument has to be regulated exactly the same as the instrument that it was recorded on for it to work properly. Well, this is an amazing recreation of Mahler’s piano playing, which is astounding! This is an orchestral work with lush strings and brass with a huge orchestration. So, in order to achieve the sustain of these rich sonorities, there are tremolos all over the place. Because if you’re trying to get the sound of sustained strings and you just play the notes, they will quickly fade away. And you certainly won’t be able to create a crescendo.

A crescendo of one note on the piano is virtually impossible.
There are nuances of tonal shading you can impart using the pedals. A crescendo is a little bit of a stretch, but there is a small amount of crescendo you can achieve by judicious use of the pedals. Starting with the una corda pedal, and then putting the sustain pedal on just as the note begins to fade out will give a little extra swell, but that’s all you’ve got to work with.
So yes, the piano is a flawed instrument. But what a wonderful instrument it is anyway, because of all the things it can do! You have this huge range of keys from the very highest notes to the lowest notes. And you’ve got the ability literally at your fingertips to play complex orchestrations that are all but impossible on just about any other single instrument. So, as flawed as it is, I love the piano! How do you feel about this? I’d love to hear your thoughts on this and other subjects. Thanks again for joining me! I’m Robert Estrin here at LivingPianos.com, Your Online Piano Resource.
