Kawai stretcherEarlier this year, Kawai introduced us to their newest GX line of pianos following nearly a 20 year run with the RX series. Continuing on with their high tech Millenium III actions made of styran infused with carbon fiber, the piano scale has also been redesigned. However there are bigger structural changes which are outlined here:

1. Stretcher widened. The stretcher is the perpendicular beam (pictured left with lock plate) that connects the left/right sides of the rim. Kawai has solidified this beam and connected it to the pinblock and frame to act as a single unit.

2. Concert key buttons. Notice that the length of the key buttons (pictured right with red bushings) are very long acting as structural reinforcement to the key. Stiffer keys mean better energy transfer to the action.

3. Longer keys in all models. This lengthens the distance from the fulcrum (pivot point) enabling both greater control in dynamics and minimizing touch difference from front to back of the key at the keyboard.

5. New tapered soundboard. Using straight grained, quarter-sawn solid spruce for the GX line, the new soundboard taper offers greater sustain and projection.

NAMM 2020 Trade Show ~ Pianos in Review

I suspect in the year 2020, we’re going to be hearing a lot of the phrase “Hindsight is 20/20”. Looking back on the last decade, a lot has changed in the world of piano manufacturing since I started attending the NAMM show (National Association of Music Merchants). While many could argue that pianos don’t really change from year to year, if you pay attention, you’ll find that they’ve changed drastically this last decade. Parts have ...

Are Hybrid Pianos the Next New Thing?

I hear a lot of talk about hybrid pianos being the next new thing and yet I believe there’s some confusion as to what a hybrid piano actually is and whether or not it can be used as a piano alternative in serious education. When we see hybrid cars driving about, from what we’ve seen in the media, it refers to an alternate power source providing some advantage in energy. While there are several kinds ...
