The Features and benefits of the CLP-645

Real Grand Expression

Real Grand Expression. This phrase defines the expressive capability of Clavinova. It is not only the full realization of the sound, the touch and the pedals, but the application of technologies nurtured by crafting acoustic pianos to perfectly integrate these three elements into a single piano. This piano produces that exact sound you want through the touch of the keys and the feel of the pedals. As you play, you will truly feel as though you are playing a grand piano.

The CLP Piano Sound

Two World Class Concert Pianos


The CLP offers two of the world’s finest 9 foot grand pianos to choose from. The CFX, Yamaha’s premier piano is a 9 foot concert grand made by the finest Japanese artisans and technicians Yamaha has to offer. The Bösendorfer Imperial is a hand made piano crafted in the Viennese tradition of fine piano making to encompass a sound with warm bass resonance, singing treble and rich tonal colors. Bösendorfer has a rich history of being the piano of choice of Franz List, Brahms and Johann Strauss.

Both of these superb pianos’ Voices are featured in the Clavinova. Tuned to perfection by a highly-experienced piano technician with the sound from each key sampled individually, Clavinova truly captures the unique tonal character of each of these outstanding instruments.

An Additional 34 sounds are present on the CLP to stimulate your musical expression.

Piano – CFX Grand, Bösendorfer Imperial Grand, SU7 Upright Piano, Bright Piano, Mellow Grand, Warm Grand, Pop Grand, Jazz grand, Rock Grand and HonkyTonk piano.

Electric piano – Stage E. piano, DX. E. Piano, Vintage EP, Soft EP, Phaser EP, DX Bright, and Tremelo Vintage Electric piano are included to help recreate your favorite, rock, pop and jazz electric piano sound.

Organ – Organ Principal, Organ Tutti, Jazz Organ 1, Jazz Organ 2, and a Mello Organ are present to cover a sampling of the wide range of organs.

Strings – Strings, Slow Strings, Choir, Slow Choir and a Synth Pad are available to be used on their own or can be layered with piano or other sounds to give greater depth and expression to what you are playing.

Bass – Acoustic Double Bass, Bass & Cymbal, Electric Bass and Fretless Bass are present so you can split the keyboard and become your own 1 man band.

Historic Instrument – Harpsichord 8′ and Harpsichord 8’+4′ are on the piano to recreate your favorite early period classical music. These voices also features historic touch settings of the Harpsichord so variation of touch will produce the same sound.

Virtual Reality CFX Head Phone Sound


When choosing the CFX Grand setting while wearing headphones the musician will be immersed in the sound of CFX as if they are sitting at the real acoustic piano. Binaural sampling uses special microphones that capture not only the sound but the location the sound is coming from to give the human ear a 3d effect.

The sound is heard just as it was played.

The grand piano voices of the Clavinova CLP 635 were obtained by recording the sounds of a Yamaha CFX concert grand piano. A single piano best suited for recording was selected and then tuned to the finest possible condition by a veteran piano tuner. All the sounds were recorded with meticulous detail resulting a beautiful, harmonious piano Voice.

Smooth tonal transformations perfectly matched to key pressure

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.

From staccato to legato – superbly expressive sound that responds to the player’s touch

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.

Key-off Samples

The moment your 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 the sound. Key-off samples feature actual recordings of these changes, offering a faithful reproduction of the most subtle nuances in the piano’s tone, creating a more realistic overall sound.

The CLP Piano Action

Natural Wood X keyboard—the feel of an acoustic grand

Natural Wood X (NWX) keyboards are created using unrivaled expertise that Yamaha has acquired through more than a century of crafting fine pianos. Just as with grand pianos, the material used for Natural Wood X keyboards is cut from wood that has been carefully dried specifically for use in making musical instruments. Only the best wood from the finest part of each tree is selected, resulting in a keyboard that is more resistant to buckling and warping than common laminated wood keyboards. The Yamaha Natural Wood X keyboard features a three-sensor configuration, which accurately senses and interprets the behavior of the keyboard for a response that feels very similar to that of a grand piano. This allows you to vividly perform smooth, flowing passages or light trills, techniques used in many pieces such as Für Elise.

Synthetic ivory keytops – a pleasure to play even after hours of performance

Reproduces the gentle, tactile surface of the ivory keyboards once used in only the finest pianos. It features highly-absorbent material that prevents fingers from slipping even after hours of performing, while retaining the ideal texture and feel.

Keyboard Stabilizers – Yamaha-unique mechanisms for improved keyboard stability and durability

Keyboards fulfill the vital role of transforming emotion from your fingertips into sound and therefore, must be smooth to play in order to maintain superb touch for prolonged performances. That is why Yamaha has fitted Keyboard Stabilizers to all 88 keys, offering players a natural touch and improving the stability and durability of the keyboard.

Natural feel, even on the back-end of the keys

Clavinova key tips are far from the fulcrum, so the keys sink smoothly when played near the base
The keys on the Clavinova are constructed so that the support point hidden inside the instrument body is as far from the key tip as possible, improving playability and comfort, even deep on the back of the key.

This construction provides good key travel, even when performing pieces played mainly on the black keys and the backs of the white keys, allowing nuanced variations in touch and broadening your expressive range.

CLP Digital Piano Technology

THE MECHANICS OF SUPERIOR SOUND

Full-body resonance, just like an acoustic piano

Similar to an acoustic piano, the Clavinova is calibrated carefully, with speaker positioning and body materials checked to ensure that the entire instrument resonates optimally. For a sound image that is very close to the grand piano, these instruments feature Tone Escapement in several locations throughout the body that allow the sound from the speakers to be projected to the listener’s ears without being trapped inside the instrument.

Acoustic Optimizer – Regulation to ensure a balanced tone

The body of the Clavinova contains Acoustic Optimizers that regulate the flow of sound and control tone. A new technology springing from Yamaha’s intimate knowledge of the acoustic properties of the interiors of musical instruments, Acoustic Optimizers deliver natural, smooth feel and tone across the entire keyboard.

Wireless Bluetooth Audio


You can play your music wirelessly through the Bi-amplified audio system of your CLP. You can send data such as Mp3 files from your bluetooth enabled device to the speaker system of your Clavinova. Now you can enjoy using the CLP with your apps and music coming through the same speaker system as you play along.

Easy-to-use Interface


An easy-to-read LCD and intuitive layout enable simple operation of your Clavinova, giving you more time to focus on playing. An intuitive button interface allows you to sit down and play the Clavinova before diving into the owners manual,

Multi-track Song Recorder

The recording function featured in Clavinova digital pianos allows you to record your performances with a single touch, which is useful when you want to review or archive your playing. You can record up to 16 tracks for simultaneous playback allowing you to create your own songs using different sounds, or record each hand separately.
* Recordings are made in MIDI format, and can also be recorded to USB flash memory. Compatible software is required for playback of recorded data on a computer.
*WAV and recording functions available with optinal flash drive

New reverb that offers dynamic ambience and spatial effects

A new reverb system allows you to experience the sensation of playing in a large concert hall, cathedral or other venue, adding depth and atmosphere to the sound. Now you can experience concert hall ambience and spaciousness in the privacy of your own home.

Twenty Different Rythms

Play along with 20 different built in rhythms to add excitement to your playing. Adjust the tempo of each rhythm to match your song and choose the style that complements your song. Pop and Rock feature 7 different versions, Jazz setting offers 4 different configurations, Latin is available in 5 distinct styles, and 4 different Kids & Holiday rhythms round out the selection.

Piano Room Setting

New to the CLP-635 and up series is the piano room setting! You can customize the voices in the piano group bank by adjusting various parameters such as the lid position, string resonance, damper resonance, Brightness, Keyboard Touch, Virtual Resonance Modeling, Key off sample and Half Pedal point

IAC (Intelligent Acoustic Control), perfect for playing at home

The ability to adjust performance volume is extremely useful at home where players may not always be able to play at high volume levels. Often at low volumes, both bass and treble may become difficult to hear. To counter this, Clavinova is equipped with Intelligent Acoustic Control (IAC), which adjusts the sound automatically, allowing players to enjoy balanced sound at any volume level.
