Your Living Room Just Got a Whole Lot More Musical
Picture this: It's a Tuesday night, you're messing around with a melody you've had stuck in your head all day, and suddenly the DGX-670 adds a full jazz trio backing you up — bass, drums, the works — adjusting to your playing in real time. That's the kind of thing the Yamaha DGX-670 was built for. This isn't just a digital piano. It's what happens when Yamaha takes their concert grand piano sound (the same CFX that costs as much as a car), pairs it with 88 fully weighted keys, and then throws in 630 instrument voices and 263 auto-accompaniment styles for good measure. Whether you're a pianist looking for a solid practice instrument, a songwriter who needs realistic backing tracks, or a family that wants one keyboard everyone can actually use, the DGX-670 covers a lot of ground without costing a fortune.
The keyboard action is Yamaha's Graded Hammer Standard — heavier in the low end, lighter up top, just like an acoustic piano. The matte black keytops help with grip during longer sessions. And with 256-note polyphony, you can layer sounds, use the accompaniment features, and hold the sustain pedal without worrying about notes dropping out. It's a workhorse that doesn't feel like one.
The CFX Concert Grand (Without the Concert Hall Price Tag)
Yamaha's flagship 9-foot CFX concert grand is the kind of piano you hear in world-class recital halls — sparkling highs, powerful bass, the whole dynamic range. The DGX-670 gives you that sound, sampled in stereo and enhanced with Virtual Resonance Modeling. VRM recreates the complex sympathetic resonances that happen inside a real grand piano — when you press a key, other strings vibrate in response. When you use the damper pedal, the DGX-670 calculates how all 88 notes interact in real time. It's the difference between a piano sound and a piano experience.
Beyond the pianos, you get 630 voices spanning electric pianos, organs, strings, brass, synths, and more. Many of these are pulled from Yamaha's high-end Clavinova and Tyros lines — things like Super Articulation voices that respond to how you play (breath noise on saxophones, fret noise on guitars). The full-color LCD screen makes it easy to navigate, and you can blend two voices together in Dual Mode for richer textures.
Auto-Accompaniment That Actually Listens
Here's where the DGX-670 gets fun. With 263 accompaniment styles covering pop, jazz, Latin, rock, R&B, and more, you can turn a simple chord progression into a full band arrangement. The Adaptive Style feature analyzes your playing in real time and adjusts the accompaniment to match your intensity — play harder, and the band ramps up with you. Play softer, and it pulls back. It's like having session musicians who never complain about rehearsal time.
Smart Chord mode lets you trigger full chords with single notes, which is great for beginners or anyone sketching out song ideas quickly. There's also a 16-track recorder, Bluetooth audio for streaming backing tracks from your phone, and a microphone input with vocal effects. You can display sheet music on the screen, import MIDI files, or connect to Yamaha's Smart Pianist app for even more control.
Built-In Speakers and Expandability
The DGX-670 has four built-in speakers — two 12cm woofers and two 5cm tweeters — powered by dual 6-watt amplifiers for 12 watts total. That's enough for home practice and small gatherings, though if you want more volume or plan to gig with it, you can run the headphone output to an external amp or PA. Speaking of headphones, the Stereophonic Optimizer creates a more natural, spacious sound when you're playing privately, so it doesn't feel like the piano is crammed inside your skull.
If you want the full furniture-piano look, Yamaha offers the optional L-300 matching stand and LP-1 triple-pedal unit (sold separately). The LP-1 gives you soft, sostenuto, and sustain pedals with half-damper support, which adds a lot of expressive control. The base package includes a music rest, sustain footswitch, and power adapter.
