Why do digital pianos use graded hammer action for the keys?

Digital pianos use graded piano action so that the piano keys will have a heavy feel. This is something associated with the traditional digital piano it is designed to digitally imitate.

To achieve the heavy and not lightweight feel, these pianos attach a small hammer under the keys as a lever. When the keys are struck, the pressure and resistance make it feel like what is obtainable with the acoustic piano.

How does the acoustic piano produce sound?

The acoustic piano produces music sound when the hammers hit one, two, or three strings attached to the keys struck. The vibration of the strings, caused by the contact between the hammer and the strings, makes the instrument produce sound. The hammers connect to the keys through a lever, causing the weight and minimal resistance associated with striking the acoustic piano keys.

How does the digital piano produce its sound difference from the acoustic piano?

The digital piano produces musical sound by avoiding the traditional hammer-string mechanism associated with acoustic pianos. Instead, sounds from a top-quality acoustic piano are recorded and instilled into the digital piano. However, unlike the music keyboard and synthesizer, the digital piano is aimed at looking and feeling like the acoustic piano. As a result, features that make it seem this way are installed. The use of heavy weighted keys is one such feature.

How does a digital piano achieve heavyweight keys?

To have heavyweight keys like the acoustic piano, manufacturers install a small hammer-like device that creates a certain form of pressure and resistance. This is unlike what will be obtainable if a string was simply placed underneath the keys.

Playing the low pitched notes on the acoustic piano presents more resistance and requires more pressure. To replicate this feature on the digital piano, piano manufacturers grade the amount of pressure that will be required to play the notes. In the same vein, playing a high pitched note will require less effort than a low pitched note.

Polyphony

As stated in the list above, the Yamaha P115 and P125 offer 195 polyphony notes. But first, just in case you are in the dark, what is polyphony?

Polyphony is the number of notes that can be played or sung at the same time. It is based on the music theory of harmony. This implies when more than one melodic note or line is used at/around the same time. On the piano, it refers to the number of notes with varying sounds that can be played. For digital pianos such as the Yamaha P115 and P125, you have as many as 195 polyphony notes available.

Does a piano need so many polyphony notes?

A regular piano does not need so many polyphony sounds. This is because you cannot play more than 10 notes all at once, given the number of fingers you have. Except for studio works and music production that may require unrealistic harmonic accompaniment, you do not need so many polyphony notes incorporated in your piano. However, this should not stop you from getting a piano with other impressive features.

To understand more about this, you can watch the video below.

Who needs a transpose function?

The transpose function on the music keyboard, synthesizer, or digital piano is needed by those who feel very comfortable, or can only play one or very few music keys.

You will still play on your convenient key while getting the result for playing in the key you transposed to.

Do you need to use the transpose function on the piano?

Learners should especially be careful with how they use the transpose function. A beginner can get relaxed playing on only one key because of the transpose function. So, instead of learning how to play on all 12 music keys, he/she settles for using the transpose button all the time.

Also, there is the headphone jack port. If you choose to hear every tiny bit of what you are playing, you can use a headphone fixed into the headphone jack port. This port also helps you practice without disturbing anyone else. You can think of it as an advanced practice pedal.

Modes- Duo, Split, Dual.

The Yamaha P115 and P125 come with different sound modes. These sound modes can be achieved by pressing defined buttons on the instrument.

The split mode function is also known as the key split. This function can be used to add harmonic variance by using other mimicked instruments on the piano.

What is a dual-mode on the piano?

A dual-mode is a function on the piano that combines the sounds of more than one instrument for a single note. However, one instrument is bound to have dominance over the other. For instance, you can have both the electric guitar and xylophone fused, with the xylophone having dominance.

You can use the Piano Controller with the Yamaha P115, and the Smart Piano App with the Yamaha P125.

As an added advantage, the Smart Pianist App suggests helpful chords as the songs keep playing. You can also use the app to save customized sounds and settings.
