Yamaha Clavinova CSP-255 Smart Digital Piano
Yamaha CSP255 | The Smartest Way to Learn and Play Piano
The Yamaha CSP255 is a next-generation digital piano that transforms learning and playing into a joyful, intuitive experience. With groundbreaking features like Stream Lights and full integration with the Yamaha Smart Pianist app, the CSP255 is designed to help you discover music on your terms—whether you’re just starting out or already playing confidently.
From the rich, resonant tones of the Yamaha CFX and Bösendorfer Imperial grands to the advanced GrandTouch-S™ keyboard, every detail is crafted to deliver an immersive, piano-like feel and sound.
Guided Learning with Stream Lights
Never read sheet music? No problem. The Yamaha CSP255 uses intelligent Stream Lights—a revolutionary light-up guide above each key—to show you exactly what to play next. Linked to the Smart Pianist app’s interactive sheet music, it guides your hands through each song with visual cues.
Slow the tempo, isolate left or right hand parts, or enable the guide function which pauses playback until the correct note is played—ideal for learning at your own pace.
Yamaha Smart Pianist App Integration
Pair your smart device with the CSP255 via Bluetooth MIDI and unlock a world of control using the Smart Pianist app. Access over 800 instrument voices, change acoustic environments (from concert hall to cathedral), and explore 495 backing styles and 403 preset songs—all from your phone or tablet.
With Audio to Score, the app can even turn your favourite audio tracks into playable chord charts, generating accompaniments and syncing them with the Stream Lights to guide your performance.

- Yamaha CFX and Bösendorfer Imperial voices
