Without knowing which style disklavier you're interested in (Upright,
Grand, GranTouch) it's difficult to be specific as there are well over
30 Disklavier models available. I'll try to elaborate on some of the
major differences, and if you have a particular model in mind for
comparison, just post a request for clarification and I'll go further.
There are a number of differences between models in the Yamaha
Disklavier line of products. The specifications for each of the
models are available on Yamaha's website.
Yamaha seems to divide their Disklavier line into 3 parts:
1) Disklavier Grand Pianos
2) Disklavier Upright Pianos
3) Disklavier GranTouch Pianos
Each product line has a catalog page on Yamaha's website, with links
to separate web pages for each model:
Disklavier Grand Pianos
Disklavier Upright Pianos
Disklavier GranTouch Pianos
The Disklavier grand pianos range in size from 4'11" to 9' length. As
you might expect, there's less variation in size for the Uprights,
ranging from 44" to 48" width.
When comparing models, you'll probably find differences in the sensor
system (how the piano tracks key presses and pedal motion), the media
it uses (does it use Floppy disks? CDs?), how much memory is in the
piano internally, and the control unit interface presented to the user
(LCD display). The high-end Yamaha Disklavier Pro 2000 even comes
with a touch screen Windows computer attached to it! See the photo
and product specifications for the Pro 2000 here:
Some of the differences listed specifically for Pro series are
"a host of new additional features, including Silent functions, XG
instrumental tone generation, and MIDI and PC connections, extend
their range to take advantage of a new era of musical opportunities."
"Sensors on the DC6PRO register not only the downstroke but the
release speed of the keys, a major advance in Disklavier technology"
Interestingly these same "new" features seem to appear in some of the
Mark III line of Disklavier Grand pianos, so the distinction between
Pro and non-Pro Disklavier may not be as sharply defined as one might
For additional information, you might want to contact Yamaha for a
copy of their free Disklavier promotional CD, "The Piano of Unlimited
Potential". According to several of Yamaha's web pages, you can get a
copy of this CD simply by emailing Yamaha at
email@example.com and providing your NAME and MAILING
ADDRESS. (This offer is for US residents only.)
In Google, I searched for "disklavier yamaha" and found links to the
yamaha product catalog. Then I explored those pages.
I hope this answers your question and gives you some resources to work
with. Again, should you have questions about a specific Disklavier
model, please don't hesitate to request a clarification prior to
