Beautiful, slim piano design with a feeling of luxury


Although the CLP-S406 features a slim (only 17 inches deep!) design, it’s not slim on features or performance. The simply designed cabinet maintains the appearance of a piano with scrupulous attention paid to every detail, including the rectangular silhouette, key cover and beautifully balanced front legs


"Real Grand Expression"-Touch, tone and pedals are perfectly integrated to make you feel like you are playing a grand piano


The phrase, “Real Grand Expression” defines the expressive capability of Clavinova. It is not only the full realization of the tone, touch and pedals, but the application of technologies nurtured by crafting acoustic pianos to perfectly integrate these three elements into a single piano. This piano produces the 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 sound is heard as precisely as it was played. "RGE Sound Engine" provides playing response and expressive capability


Variations of sound according to touch



The RGE (Real Grand Expression) Sound Engine delivers the ultimate expressive capability for the CLP Series. The new CLP Series uses the RGE Sound Engine, the next-generation piano sound source. It improves upon the Pure CF Sound Engine, which earned high praise in the CVP Series, and lets you enjoy the playing response and expressive capability of a concert grand piano. It features a new Smooth Release function which can express sound with great clarity, and clearly enunciate staccato notes with the sound of lingering resonance heard when gently lifting your fingers from the keys. It succeeds in capturing the essence of a piano performance to create grand piano-like, richly expressive experiences


Dynamic change of sound is dependent on touch




An acoustic piano is a musical instrument whose sounds linger for a long period of time. The strength of touch varies not only the volume, but also the timbre from bright to dark. Clavinova produces deep resonances by using piano sounds that have been accurately sampled for their entire length. Proprietary technology creates smooth and dynamic changes according to the strength of the touch. Additionally, to achieve a performance feel rivaling that of a grand piano, the touch was carefully refined by many pianists who played it and gave their feedback for Yamaha’s research and development.


Piano Voices embody the careful attention only a piano manufacturer can give


The grand piano Voices of a Clavinova were obtained by recording the sounds of a Yamaha concert grand piano, an instrument that led to the creation of the CFX, the piano selected for a performance by the 2010 winner of the famed International Frederick Chopin Piano Competition. 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 resulting in a sound that demonstrates not only the beauty of each note, but the harmonized sound of a single piano


256-note polyphony lets you play without notes dropping-out, especially in dense passages of music


When you play fast phrases or superimpose chords while pressing the sustain pedal, you want to be able to perform without notes dropping out. The Clavinova provides 256-note polyphony so you can enjoy complex works such as those by Liszt or Ravel, which feature numerous pedal presses, with no limitations. As your playing improves over the years, your Clavinova will continue to let you make the most of your abilities.


Diverse piano Voices that you can choose to match the piece you want to play


Clavinovas are provided with distinctive piano Voices in addition to the piano Voices that offer playing response like that of a concert grand piano. These include a piano for ballads that gently emphasized the attack, a piano for jazz that adds depth to the sound, and a piano for popular music with a bright, rich sound. To ensure that the sound conforms closely to the genre, adjustment of each piano Voice focuses on the resonance, or the sound produced when you lift your finger, and other delicate nuances. Each time you play, you can enjoy the perfect piano tone without having to make any adjustments.


The "GH3 (Graded Hammer 3) keyboard" faithfully reproduces the touch of a grand piano


The touch of the Clavinova keyboard has been praised by pianists for a performance feel that makes you forget it's a digital piano. The secret behind this superior touch is the same hammering system and spring-less mechanism as a grand piano. Depending on the weight of the hammer, the force of your touch and the natural key return when you release it, the Clavinova faithfully reproduces the keyboard touch of an acoustic piano from the heavy feel in the lower range to the light feel in the higher range. Also important is Yamaha's unique three-sensor system, which accurately senses and interprets the behavior of the keyboard, just like a grand piano


"Synthetic ivory keytops" remain tactile during long performances


Pianists enjoy a touch that clings firmly to their fingers, just like the ivory keyboards historically used in top-class pianos. Synthetic ivory keytops feature a soft, slightly porous surface that gives keys added grip and natural friction for improved ease in playing, especially during long performances or practice sessions. The keys' smooth, refined texture imparts a feeling of luxury and is easy to clean.


"Keyboard Stabilizers" enhance the keyboard's durability


The keyboard must respond perfectly to the touch of your fingers so the notes sound just as you intend. Because the keyboard plays such a critical role, it must allow you to play smoothly and maintain good touch for long periods of time. That's why all 88 keys are equipped with Keyboard Stabilizers. This not only lets you play with a natural touch, it greatly improves the stability and durability of the keys.


Keys have a long distance to the fulcrum offering easy-to-play touch, even to the base of each key


The keys provide a pleasing touch down to the base, because the distance from the tip of the key to the fulcrum is extremely long. When playing a piece that uses many black keys, even when you press a white key near its base, the key sinks softly, maintaining the nuances of soft and hard key strokes.


The acoustic system produces acoustic piano sound as if the instrument itself is resonating


Because Yamaha places so much importance on the joy of playing, the speakers, amps and other acoustic systems have been optimized so the player hears nothing but stunning sound during a performance. These musical instrument-like resonances give the impression that the Clavinova is more acoustic than it is digital.


Using the pedals provides realistic overtones that accurately convey all sound changes


Stereo Sustain samples provide the mellow reverberations created as you depress the damper pedal. Damper Resonance similarly produces broad and deep resonances when the pedal is used. The result is realistic sound, just as if you were playing an acoustic piano. You will even hear the subtle changes that occur according to whether the player begins to press the pedal before or after striking a key. You can enjoy playing impressionistic pieces, such as those by Debussy or Ravel, where half-pedal expression is important.


"Intelligent Acoustic Control" provides a full, balanced sound with rich lows and clear highs even at low volumes


Volume adjustment is convenient for playing at home where sometimes others may prefer you play softly. You've probably experienced the fact that when the volume is low, it is difficult to hear treble and bass. On a Clavinova, however, the Intelligent Acoustic Control (IAC) function automatically adjusts so you enjoy proper sound balance even at low volumes. Additionally, the volume dial automatically makes fine adjustments to overall sound of the speaker system (EQ) at low volume. This ability to adjust volume without losing the rich and balanced sound is an exclusive Yamaha benefit, ensuring you always play with the utmost sound quality.


A full selection of basic functions unique to digital pianos such as sound volume adjustment and metronome are provided


In addition to being compact and not requiring tuning, Clavinova models provide volume adjustment and two headphone jacks so you can listen to your student practice or enjoy playing duets in private. A metronome and other features help you improve your piano skills.


Two recording functions can be used selectively according to your purpose


[Recording on a Clavinova is fast and simple]. Recording is a useful way to evaluate your performances. You can record with the touch of a button and even do two-track recording, which lets you record the parts for your two hands separately, and then play them simultaneously. You can also store performances on a USB memory device.*

* Storage format is SMF. To play the files on a computer, compatible software (such as QuickTime or Windows Media Player) and sound source are required.


Record performance audio onto USB flash memory so that you can easily share your music.


The USB Audio Recorder can record your performances to USB flash memory as an audio file.* Because it can be played back without a Clavinova, you can store it on a PC to track and compare your progress or put the recordings on a CD so your family and friends can enjoy them. You can also listen to the files on-the-go by loading them on to portable media players.

* Uses WAV storage format.


Wide selection of realistic musical instrument Voices adds variety to your performances


Along with the piano voices, Clavinova also offers a wide selection of musical instrument voices, including electric piano, harpsichord, guitar and strings. Two interesting ways of using these voices are through the Dual and Split modes. Dual, which means playing two voices simultaneously, provides a rich sound by layering one sound with another-for example, piano with strings. Split lets you play different voices with your right hand and left hand-for example, piano in the right hand and acoustic bass in the left hand. By combining the voices in various ways, you can enjoy many different styles of play.


USB ports allow easy data storage and transfer


Clavinovas have a USB TO DEVICE port for plugging-in USB memory devices like flash drives and a USB TO HOST port for connecting to a computer via a single USB cable. This is a great way to conveniently store performance data, and transfer other data between your Clavinova and computer or other Clavinovas.


Includes 50 famous piano pieces-perfect for lessons!


Included is a song book containing 50 classic piano songs. Performances of each song in the book are included in your instrument-great for playing as background music or learning to play yourself. They've been recorded so you can mute either part or reduce the tempo so you can learn to play them at your own pace.


Online service lets you access new Clavinova fun at any time.


A wide selection of songs, scores and other great musical content is available at the Yamaha Online Services website.
