The sound of the finest concert grand pianos in the world
The CSP-150 features expertly sampled sounds from two world class pianos: the Yamaha CFX 9' Concert Grand and the legendary Bösendorfer Imperial. From light staccato and powerful strikes, to the "key-off" sound when a pianist's fingers lift from the keys, the essence of these pianos has been captured in world-class sound studios.

Bösendorfer Imperial
Bösendorfer has been perfecting the craft of piano creation for over 185 years. The legendary 97-key Imperial Grand has been serving artists from Franz Liszt to Tori Amos since 1909, offering the largest soundboard of all concert grands and a characteristic warm tone known as the "Viennese Sound." From dramatic presence and power to tender passion, every subtlety of this $300,000 masterpiece is at your fingertips with Clavinova.

Smooth tonal transformations perfectly matched to key pressure
Sound in an acoustic piano attenuates over a long time. Pianists can change the volume of the sound—as well as its dynamics—to achieve both mellow and bright tones by simply changing the pressure they apply to the keys. The Clavinova features long, carefully-sampled recordings of notes on a piano, reproduces them in rich detail and utilizes unique Yamaha technologies to achieve smooth tonal transitions in response to the touch of the player. Additionally, the Clavinova has been repeatedly tested and adjusted by numerous pianists in order to attain a performance feel similar to that of a grand piano.

Graded Hammer 3X Keyboard (GH3X)
The touch of the Clavinova keyboard has been praised by pianists for a performance feel that makes you forget you’re playing a digital piano, offering authentic response to the force of your touch and a natural key return. Utilizing the same hammering system and spring-less mechanism as a grand piano, GH3X actions accurately reproduce the touch of an acoustic piano from the heavy feel in the lower register to the lighter touch in the upper octaves. Even the slight clicking sensation of the escapement mechanism on a grand piano has been replicated in this Clavinova model. The click is discernible only on the lightest keystrokes, offering a true grand piano feel.

Synthetic ivory and ebony keytops—a pleasure to play
Our fingers are more sensitive than we think, and for pianists, the texture of the piano keys is extremely important. The GH3X keyboard features white keys made from the highest quality synthetic ivory, developed independently by Yamaha. The black keys are finished in synthetic ebony. Synthetic ivory keytops reproduce the tactile surface of the real ivory keyboards once used in older acoustic pianos. It features highly absorbent material that prevents fingers from slipping even after hours of practice, while retaining the ideal texture and feel. In addition to the feel, the appearance and fine texture of these keys is unmatched by any other digital piano, and is sure to inspire pianists from the moment they experience it.
