Review: Yamaha Clavinova
CSP-170 and CSP-150
The Clavinova CSP series (CSP-170 and its less-expensive variant CSP-150) boasts two marquee features: First, cascading Stream Lights above the keys guide your fingers to teach you songs and exercises, lending a game-like vibe to practice. Next—and this is the big deal—songs a CSP model can teach include those in the music library on your Apple iOS or Android device. Via what Yamaha calls its Audio-to-Score function, the CSP can analyze chords in ordinary stereo audio files, then display them as notes on a staff or as jazz-style chord charts.
