Yamaha’s Acoustic Resonance Enhancement (A.R.E.) is the latest leap forward in the evolution of piano craftsmanship. What is A.R.E.? It’s an original treatment process that we use to season the rims used in SX Series pianos. As well as reducing the moisture content in the wooden rims, A.R.E. induces chemical changes that occur when young wood is aged under optimal conditions. This enables the rims to produce the warm and sweet tones of an instrument matured to perfection. The benefits of A.R.E. have already been proven in Yamaha’s acclaimed flagship Artida YVN500S violin, L Series and A Series guitars. Now, for the first time, A.R.E. comes to an acoustic piano. The seasoned rims of the SX Series give it a sound unlike that of any other piano. A deeply intuitive sound with sustained resonance and the precision to express even the most delicate pianissimo notes.
