Choosing a Digital Piano with a Hammer Action

Choosing a Digital Piano with a Hammer Action

The fundamental difference between an acoustic instrument and a digital instrument is the presence of strings and hammers in the former. Serious electronic pianos are equipped with sensors as an analogue of strings. The more sensors, the brighter and fuller the sound of the piano will be. Three-sensor mechanics in digital pianos is considered the most modern . When choosing a model for training and, moreover, for professional performance, the hammer action mechanism is the defining criterion – without it, the keys of the instrument will simply be “inanimate ” .

The hammer action piano has an element of tactile difference when the keys are pressed – the lower octaves are much heavier, and the upper register is almost weightless. This phenomenon is called keyboard gradation and is present by default on digital pianos with hammer action .

The article presents the characteristics of the most optimal options for electronic pianos of the type under consideration, based on customer reviews and the current rating of digital piano models with a hammer action system in terms of price-quality ratio.

The tools are available in a variety of colors and designs.

Piano and Hammer Action Piano Features

Choosing a Digital Piano with a Hammer ActionThe key nuance of the classic keyboard instrument is its sensitivity to the touch of the fingers and the force of pressing.

At the same time, modern touch digital pianos even have an advantage over acoustic models. It consists in the ability to adjust the degree of responsiveness of the hammers. So, if it is difficult for a small student to fully play due to age, an electronic model with a hammer-type system allows you to adjust the sensitivity to a specific situation and performer. For a professional musician, it is also possible to customize the mechanism individually to fit your hand.

More expensive digital pianos have an advanced system that fully reproduces the classic hammer action . In small-sized electronic pianos , by and large, there is no mechanics, only its analogue, expressed in the graduation of the keyboard, takes place. That is why for full sounding, movement and feedback of the instrument’s keys, virtuosity and brightness of performance, it is better to give preference to more advanced samples with a touch system.

Such models will be a significant help in learning and achieving goals in the field of piano playing.
