In upright pianos, where the strings are mounted vertically, the hammers rely on springs to return to the at-rest position. In addition, grand pianos utilize a double escapement mechanism that allows keys to be played rapidly in succession, without first letting the key return all the way to its starting position. Because the strings are mounted horizontally in grand pianos, the hammers return to their rest position due to the force of gravity, under their own weight. The difference in action is one of the main reasons why playing a grand piano feels very different than playing an upright model. The “feel” of an acoustic piano is most often described as its “action.” This can be adjusted by a skilled technician so that the pianist encounters greater or lesser resistance as notes are played. And the entire premium Clavinova digital piano line provides fully authentic touch thanks to cutting-edge technology such as weighted “Grand Touch™” keyboards that feature real hammers and graded action (see below for more information). Yamaha ARIUS digital pianos all have weighted keys and built-in consoles. Yamaha Portable digital pianos, as well as our two Stage Pianos (the CP73 and CP88) combine portability with weighted keyboards.
Digital pianos, including some portable models as well as most “stage” models (keyboards designed for live performance), will typically have weighted keys. Unweighted keys (which are usually spring-loaded) are most often found in synthesizers and entry-level digital keyboards. A complex series of levers are attached to each key of an acoustic piano. Use a delicate touch and the note will be soft and less strident strike with greater force and the extra pressure will cause the hammer to hit the strings harder, resulting in a louder, brighter sound. This system has a natural weight or resistance that you can feel as you play a piano, and it’s that resistance that helps you gauge how hard to hit a key to get the sound you want.

Read on … What Are Weighted Keys?Īs the name implies, these are keys to which weights have been added so as to simulate the complex mechanics that occurs when a key is depressed in an acoustic piano - a series of levers that eventually cause a hammer to strike a grouping of two or three strings. In this article, we’ll take a look at the benefits offered by weighted keys, and will discuss the various systems in common use today. (If you’re already a pianist, you’ll definitely want an instrument with weighted keys, for reasons we’ll explain shortly.) The answer mostly comes down to whether or not your ultimate goal is to play piano.
One of the many questions you need to ask yourself is: Do I need one with weighted keys?
You’re about to buy a digital keyboard instrument.
