More about the product

88 Scaled Keys with Weighted Hammer Action

The Casio Privia PX 870 Digital Piano is equipped with 88 Scaled Keys with Weighted Hammer Action. This means that the keys have a realistic feel that mimic the touch and response of an acoustic piano. They are weighted so that the lower notes require a bit more pressure to play than the higher notes, just like an acoustic piano. This makes playing the piano more enjoyable and provides a great experience for beginners and professionals alike. It’s like having a real piano at home!

The Weighted Hammer Action is a great feature because it makes the keys respond to the touch of the player. When playing a piece, the keys will react differently depending on how much pressure is applied. This allows for a much more expressive performance and allows the player to create dynamic performances.

In addition, the Weighted Hammer Action helps to create a more realistic sound. When the keys are pressed, the hammers strike the strings of the piano, creating the sound that is heard. The Weighted Hammer Action helps to simulate the sound of a real acoustic piano.

As a Pro Tip, make sure to adjust the sensitivity of the keys to your playing style. This will help you sound your best and get the most out of your piano playing.

So, if you’re looking for a piano that feels, sounds, and responds like a real acoustic piano, the Casio Privia PX 870  is definitely the one for you!

4-Speaker Sound Projection System

The Casio Privia PX 870  has a great feature – the 4-Speaker Sound Projection System. You can imagine it as four mini speakers lined up in the back of the piano, so the sound is projected outwards as if it was coming from the actual strings of a real piano. It gives you a realistic sound, no matter where you’re sitting.

It’s like having a real-life orchestra at your fingertips – no matter where you are in the room, you’ll enjoy the same sound. It’s almost spooky how realistic it is! And, as a bonus, it won’t annoy your neighbors when you practice.

But how does it work? Well, the four speakers in the back of the piano vibrate when you press a key, and the sound is projected outwards. This technology creates a 3D sound effect that makes it sound like the sound is coming from the strings of a real piano.

Pro Tip: For the best sound experience, make sure you have the speakers pointing outwards toward the room. That way, the sound will be evenly distributed throughout the room.

Detailed Resonance in Piano Tones

The Casio Privia PX 870 Digital Piano has a truly unique feature – detailed resonance in its piano tones. This feature helps to create a more immersive and realistic piano sound. It gives you a full range of sound, from grand pianos to harpsichords, and helps to make the music come alive.

Joke – Have you heard the one about the piano tone? It was so detailed you could hear the resonance!

The science behind this feature is actually quite simple. Basically, when you play a note on the piano, the sound waves travel through the air, reflecting off the walls and objects in the room. The more objects in the room, the more the sound is reflected and the richer the sound becomes. This is what the detailed resonance feature on the Casio Privia PX-870 Digital Piano is designed to replicate.

Pro Tip – To get the most out of the detailed resonance feature, make sure you’re playing in a room with plenty of objects for the sound waves to reflect off of. This will create the richest sound possible!

Our Casio Privia PX 870 Digital Piano is an amazing instrument that features powerful sound projection. This means you can be sure that your music will come out loud and clear, no matter where you are playing. It’s like taking a mini-concert hall with you wherever you go.

Here’s the joke: You can be the biggest star on the block with the Casio Privia PX 870 Digital Piano – you’ll sound like a million bucks!

Now, let’s get into the science. Our digital piano uses advanced sound projection technology to create a rich sound that fills the room. It’s like having a real grand piano in your living room, but without the extra space!

Pro Tip: When playing at home, use the built-in speakers to really fill the room with sound!
