The Yamaha CSP-170 Clavinova Smart Piano combines the craftsmanship of a beautiful digital piano with the ease and power of an iPad to help you learn to play any song from your iTunes library. The CSP-170 comes with over 700 high quality instrument sounds and a weighted Natural Wood X (NWX) keyboard with synthetic ivory white keys and wood grain ebony keys for exceptional touch and expressive response. And the free Smart Pianist iOS app recognizes the chords from nearly any audio file in your iTunes library to create instant sheet music and chord charts! Together with the CSP-170’s streaming lights note-learning system, it’s never been easier to learn to play your favorite songs!

World Class Sound

With two world-renowned concert grand pianos available at the touch of a button, the CSP Series lets you choose the perfect piano tone for the music you want to play. Offering far more than just sampled sounds, the CSP Smart Piano Series reproduces the Yamaha CFX concert grand and the legendary Bӧsendorfer Imperial in meticulous detail.

Realistic Piano Touch and Action

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 the same action and three-sensor configuration as Graded Hammer 3X keyboards, 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.

Convert Any Song Into Sheet Music

Connect the CSP-170 to the SmartPianist App for iOS or Android devices, load your favorite song, and instantly generate chord charts and sheet music. Choose from dozens of chord patterns, and even transpose the song to any key – both in the sheet music and the audio playback!

Learn To Play With Streaming Lights

The CSP-170 now features Streaming Lights, which not only show you which notes to play, but when. Red lights indicate white notes, blue lights indicate black notes, and you can always see ahead of time which notes are coming up in the song. The SmartPianist App comes preloaded with a huge library of classical and popular songs, all of which take advantage of the CSP-170’s streaming lights feature to make learning to play more fun than ever!
