Yamaha CLP-645B

Yamaha CLP 645 B Clavinova

The CLP-645 is the mid-range Clavinova CLP, offering powerful sound and a superb Natural Wood (NWX) keyboard action. It features the sounds of the flagship Yamaha CFX concert grand and the Bösendorfer Imperial that sound pristine through its bi-amplified internal sound system. And the Clavinova Virtual Resonance Modeling emulates the more complex elements of playing these acoustic instruments. Bluetooth audio lets you stream music from your portable smart devices, wirelessly! Record your own performances and compositions using the built-in USB audio recorder to archive your musical achievements or share them with friends and family. Traditional on the outside but modern inside, this instrument is a great piano for musicians of all skill levels.

Clavinova is an innovative lineup of digital pianos that have continued to evolve while seeking to provide the touch and tone of a concert grand piano—the ultimate symbol of piano excellence. This authentic grand piano experience is the product of the knowledge and expertise that Yamaha has accumulated over more than 125 years of crafting acoustic pianos. Utilizing state-of-the-art technology to achieve grand piano quality, Clavinova digital pianos offer an inviting playing experience that is perfect for players of all levels. They emulate the touch and tone of a grand piano to make the transition from digital to acoustic piano a seamless and enjoyable one.

In a grand piano, sound resonates throughout the body of the instrument, producing a rich reverberation that envelops the listener in sound. This phenomena is reproduced perfectly in the Clavinova through enhanced Virtual Resonance Modeling (VRM). The original VRM calculates the various states of the strings for each of the 88 notes on the keyboard, from one instant to the next, and timing and depth of damper pedals pressed. The enhanced VRM now also calculates aliquot resonance in the upper octaves, and the full resonance of the soundboard, rim, and frame. This technology allows for vivid, bright, richly-varied expression that reflects the limitless number of factors inherent in piano performance.

Featuring Yamaha Smooth Release technology, Clavinova offers the crisp tone heard when playing staccato as well as the lingering sound produced by releasing the keys more. This provides finely-nuanced response to the pianist’s playing.

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.

The moment a pianist’s fingers are lifted from the keys of a grand piano, subtle changes occur in the instrument’s tone as the damper is lowered onto the strings to mute its sound. Key-Off samples features actual recordings of these changes, offering a faithful reproduction of the most subtle changes in the piano’s sound, allowing for a more realistic performance.
