Ideal for beginners and accomplished pianists alike, the white Yamaha DGX-670 is a portable digital grand piano with the authentic feel of an 88-key weighted-action keyboard, 630 high-quality piano and instrument sounds, and a stylish visual appeal with a modern body, curved edges, and luxurious wooden accents.

The DGX-670 offers the sound of a precisely sampled Yamaha flagship 9′ CFX concert grand piano, which is sonically characterized by an exquisite tone across the entire dynamic range. The company’s Graded Hammer Standard (GHS) keyboard features weighted action with heavier touch in the low end and lighter touch in the high end, just like the hammers inside an acoustic piano. Great for the aspiring pianist, practicing on the GHS action helps build the proper finger technique and strength for when the time comes to perform on an acoustic piano.

With 263 advanced automatic accompaniment styles that provide backing in a wide range of musical genres (including pop, R&B, and jazz), the ability to display sheet music to aid practice, Bluetooth audio to connect a smart device and play along with your favorite songs, a microphone input to sing with studio-quality FX while you play, two powerful speakers, and a headphone jack for quiet practice, the DGX-670 is well suited to help you discover (or rediscover) your love of making music, from straight-ahead piano playing to playing along with other instruments.

Navigating the wide selection of functions is made quick and easy thanks to a full-color LCD screen that features a simplified user interface and enlarged buttons on the front panel that feel comfortable to the touch.

You can mount the DGX-670 on the L-300 furniture stand and attach the LP-1 piano-style triple-pedal unit (both available separately) to provide an even more comfortable piano-playing experience. With matching white finish, these two additions help transform your keyboard into a compact grand-piano replacement, great in a living room, bedroom, classroom, or lounge. A music rest and a footswitch are provided.

Authentic Piano Touch, 88-Key Weighted GHS Keyboard
The Yamaha Graded Hammer Standard (GHS) keyboard features is appropriately graded to mirror heavier bass and lighter treble hammers and accurately reproduce the distinctive touch of an acoustic grand piano.
Powerful Speaker System
The two-way system features two round 4.7″ speakers for warm mids and bass, and two tweeters for clear treble. The piano sound is designed to feel immersive from the bench, while optimizing the impact of the accompaniment.
Stereophonic Optimizer for Enhanced Headphone Experience

Accompaniment Automatically Adjusts to Your Playing
The DGX-670 is equipped with Adaptive Style, a function that automatically analyzes your playing in real time and adjusts your accompaniment to suit the mood of your music. Play with more intensity, and Adaptive Style ramps up the accompaniment. Switch to a mellower mood, and the Adaptive Style mellows out along with you.
Minimal Accompaniment for Simpler Sound
When you want to keep things simpler and just highlight the sound of the instrument you’re playing, the Simple Style function quickly strips the accompaniment down to rhythm and bass at the push of a button.
Pro Chords Played Simply
With a single finger on your left hand, the Smart Chord function lets you create entire chords, from simple pop triads to complex jazz 7th and 9th chords. Accompaniment Styles create the rest of your virtual band, so you can focus on playing your music.
Unison and Accent for More Creative Options
Unison and Accent are functions that open up a wide array of expressive capabilities. With Unison, you play a phrase while pressing the foot pedal, making the accompaniment Style play in unison with you. This lets you perform signature lines found in iconic songs, or create your own signature licks for the whole band to follow. Accent lets you add rhythmic shots to accentuate notes of your choice simply by playing a little harder.
Fun Features

Connect Wirelessly for Bluetooth Audio
You can play music through the audio system on the DGX-670 by using a Bluetooth-enabled smart device. You can also enjoy playing along with your favorite songs played directly from your smart device.
Audio Playback and 16-Track Recording
Audio files (WAV format) saved to a USB flash drive (available separately) can be played back on the instrument. You can also record your performance as audio files to a USB flash drive, making it easy to edit your recordings on a computer and share them over the Internet. The USB to Host feature functions as a two way 2-channel audio and 16-channel MIDI interface.
Identify Chords in Your Favorite Songs
Identify the chords in your favorite songs using the Yamaha Chord Tracker app (free download available separately). Practice and perform by extracting the chord sequence of an audio song stored on your device.
Lesson Features
The Lesson features offer a fun way to learn and master songs, with notation shown on the display. For example, when you practice the right-hand part, the playback of the left part and other parts will wait for you to play the notes correctly. This allows you to practice melodies and phrases smoothly, even if you are a beginner.

    I’ve owned Yamaha keyboards for 35 years. From the par 670 to the PSR SX900 those were very good keyboards but you pay for features you rarely use. The Yamaha came out with the DGX670 and designed a inexpensive keyboard that has 88 keys and most of the styles and sounds to fill your appetite to do gigs with without going overboard with gimmicks. I actually enjoy play the DGX more that my PSR SX(900.

    What to go Yamaha.

    Very happy to receive this DGX670. Prompt delivery.

    Very good service.

    I wanted to try a weighted keybed and this one feels comfortable. I have always had arranger keyboards and this one fits that also. Great voices and styles. It is not going to leave my stand because it is crowding fifty pounds and I have already set up a way to use my other keyboards. I also ordered a Casio PX-S3000 and could not get along with it so it went back.

    I researched a ton of portable keyboards and this unit provide the most features for the money. The only thing that may be an issue for some is that it isn’t truly portable. The weight makes it a beast to move great effort.

  6. Jianhua –

    I’m new to digital piano and never learned play real piano before. There are quite some to explore with this new keyboard. Some imitation of music instruments sounds very good. The noise of pushing keys seems a little too loud. But I began to get used to it after awhile.

    Look nice and sound amazing

    This bundle is very nice. It came in four boxes, and they didn’t arrive on the same day, but everything came very quickly and all was packed securely and neatly. The DGX-670 is astounding. It’s truly amazing that you can get this level of quality and performance at this price point. Voice quality is very impressive across the board, but I was especially impressed by the acoustic piano sounds. Stunning. It’s also worth mentioning that the integrated speakers are really great. They will fill most rooms with rich sound. The headphone jack is a nice feature as well. My over-the-ear studio headphones sound amazing with it. The stand is very high quality. Assembly was a breeze and all of the bolts thread into metal fasteners embedded in the wood. Very sturdy. Pedals go on easy as well and the included wire management clips are a nice extra. Finally, the bench is also terrific quality. It’s really sturdy and looks nice with the piano. Overall, this is a terrific buy that I am very glad to have made. I could not be happier with it.

    It is very easy to play with a ton of great features. I especially love the selections of the pianos with San easy one button switch. It is a great and fun digital piano for beginners as well as people like me who love to be creative and compose some video scores. Yamaha never disappoints me!

    The Piano will do it all. My son loves it.

    Sounds really good, especially for the price. Being able to buy the whole bundle at once helped save time and money. Everything also arrived very quickly, within a few days of ordering.
