September is National Piano Month! Isn’t it awesome that we pianists get a whole month to celebrate our favorite instrument? If you haven’t already, this is also a good month to wow your friends with some epic piano facts. Here are a few.

🎉 Celebrate National Piano Month with the 90-Day Pianote Challenge! 🥳

This September, we’re offering 90 days of Pianote membership for only $49! Come take the Pianote challenge and see how far you can go in three months. You may be surprised!


#1. It’s not your imagination: bass keys are heavier and treble keys are lighter.

It’s called graded action. As you move your way down the keyboard from high notes to low notes, the keys get longer. Bass notes also use bigger and heavier hammers. And bass strings are thicker. This all combines to make it slightly harder to press low notes than high ones.

Many digital pianos now imitate this design to give their keys a more authentic feel.

#2. You can trill faster on a grand piano than an upright piano.

Again, the magic is all in the action.

On a grand piano, the hammers return to rest using gravity. But on an upright piano, the hammers need the help of springs to return to rest. This gives acoustic grand pianos the fastest action.

According to Yamaha, horizontal grand piano action can perform around 14 repetitions per second. Meanwhile, vertical upright piano action can only perform around seven repetitions per second.

🎹 Not sure if you want to buy a grand or an upright?

If you’re a beginner, we recommend you start with an upright first from a reputable but affordable brand. Digital pianos have also come a long way in imitating authentic key action, so they are a perfectly acceptable choice and a lot more affordable.

#3. Synthesizers hark back to the 1800s

The Teleharmonium, an early electronic musical instrument, got its start in the 1897 and it was enormous. (The Mark III version weighed 200 tonnes.) Played through the telephone system, it was housed in the basement of the Metropolitan Opera House. But Thaddeus Cahill’s electric achievement was eventually abandoned because it kept interfering with naval communications.

Synthesizers made their big leap forward in the middle of the 20th century, with Robert Moog’s Moog Modular Synthesizer. Moog remains a recognizable synthesizer brand today. And while most synthesizers are digital now, analogue synths are enjoying somewhat of a renaissance.

#4. The sostenuto and sustain pedals do different things!

“What do all the different piano pedals do?” This is a common question we get. It depends on the piano, but in general, grand pianos have three pedals. From left to right:

  1. The una corda shifts the keyboard so that hammers hit only two out of the three strings they would normally hit. This slightly dampens the sound so that it’s easier to play softly.
  2. The sostenuto pedal sustains a selection of notes while leaving unselected notes unsustained, so you can play clearly over a sustained note.
  3. The sustain pedal is responsible for the “reverb” sound of piano pieces. Get comfortable using this pedal, as it can drastically improve your playing!

In acoustic uprights, the middle pedal is usually a muted practice pedal that allows you to practice in the middle of the night without annoying your neighbors. See? No excuses not to practice!

#5. Harpsichord strings are plucked. Clavichord strings are hammered.

Harpsichords and clavichords are both ancestors to the modern piano, but they sound very different.

While harpsichords have a sharp, stringy sound, clavichords are fairly quiet. But their biggest difference in the mechanism: harpsichords have little quills on their hammers that pluck the strings, while clavichords use hammers. However, not all clavichord models have keys that can be played at the same time.

#6. Mozart was a fan of the Stein action, and Beethoven was a Broadwood supporter.

The tradition of artists being associated with certain brands and models goes way back. A piano maker called Johann Andreas Stein pioneered the Stein or Viennese action, which Mozart was a fan of. The action produced a bright tone, which partners very well with Mozart’s playful composition style.

Meanwhile, Beethoven favored the craftsmanship of the Brits. Thomas Broadwood heard that Beethoven was poor both financially and in health, so he shipped over a Broadwood piano to cheer him up. The British piano, with its big, dramatic sound, was louder than most pianos and served Beethoven well, since he was hard of hearing.

#7. The most expensive piano we could find cost $3.22 million

According to Broughton Pianos, the most expensive piano ever sold was a Heintzman piano. It was bought by a private bidder at an auction for $3.22 million.

As of this article’s publication, the most expensive piano on the market is the Steinway & Sons Pictures at an Exhibition piano. Painted by Paul Wyse, it was designed after the Modest Mussorgsky piano suite of the same name.

Fazioli is a brand famous for its custom-designed pianos that are pieces of art. Pianote was fortunate to sample several of their gorgeous instruments worth as much as a house. Take a look at our adventure here!
