These specifications provide a clear snapshot, but numbers alone don’t tell the whole story. Let’s now explore each piano in more detail, focusing on their sound, materials, and features to better understand which model may be the right choice for you.
Dimensions
A key distinction between the Yamaha U1 and U3 is their size. The Yamaha U1 stands at 48” in height with a depth of 25”, making it a compact upright piano that fits well in smaller or medium-sized rooms. Despite its modest size, it delivers impressive sound projection and balance.
By contrast, the Yamaha U3 is taller at 52” and slightly deeper at 26”. These changes, combined with its larger soundboard and longer strings, give the U3 a bigger acoustic chamber. As a result, it produces more volume, richer tones, and greater overall projection, making it well-suited for larger spaces or professional use.
Materials
New Yamaha U1 and U3 pianos are built in the Kakegawa, Japan factory using high-quality materials. Their soundboards and ribs are made from carefully selected spruce, known for its resonance and tonal clarity. Each piano includes five spruce backposts for stability, while the bridge and pinblocks are crafted from hard maple to ensure strength and durability.
The U1 uses specially designed hammers to provide a responsive touch and long-lasting tone, while its acrylic (white) and phenolic resin (black) keys offer smooth touch and durability. The U3 shares these high-quality components but benefits from a larger soundboard. This gives it greater resonance and tonal depth, especially noticeable in the lower registers.
Features
The U1 and U3 are equipped with three pedals (soft, mute, and damper), a fallboard lock, and Slow-Close fallboard system that prevents slamming.
Where the U3 stands apart is in its enhanced design. It incorporates Yamaha’s patented Floating Support System, a feature adapted from their grand pianos. This allows the soundboard to vibrate more freely, resulting in a richer tonal palette across the bass and mid-range.
Case & Finish
When comparing the U1 and U3, both are similar in design aside from the larger height and depth of the U3. Each model features an extra-wide music desk and a top lid that can be flipped open for extra projection.
As for the finishes, the new U1 offers a wider range to choose from and is available in polished ebony, satin ebony, polished mahogany, satin American walnut, and polished white, while the
new U3 is only available in polished ebony, satin American walnut, and polished mahogany.
Hybrid Options
Yamaha also offers both models with integrated hybrid technologies. The U1 is available in three versions: Disklavier (DU1 ENST), TransAcoustic (U1 TA3), and SILENT Piano (U1 SH3).
The U3 can be purchased as a TransAcoustic (U3 TA3) or a SILENT Piano (U3 SH3). This makes both models suitable for pianists who want to combine acoustic performance with digital innovation.
Price
Now that we’ve gone over the specs and features, you probably want to know how much is a Yamaha U1 piano and how much is a brand new Yamaha U3 piano? The Yamaha U1 price (MSRP) for a new model starts at $11,999.00.
The Yamaha U3 price (MSRP) for a new model starts at $15,699.00. It’s important to note, that prices may vary based on the finish and for hybrid Disklavier, TransAcoustic, and SILENT Piano models.
