When i was younger there were these books called “Where’s Waldo?” They consisted of busy cartoons where you had to find this one character named Waldo. I don’t know if you’ve ever seen those puzzles where they’ve changed 10 things in two different pictures and you have to find the differences but today’s post is something similar to that…. let me explain.
Last week 2 pianos came into my store – a C3 and a G3. For those who don’t know, both of these are famous Yamaha models of the same size – 6’1″ grand pianos. Both are spectacular. They made both of these models overlapping the manufacturing dates for almost 25 years! What is rare for me though is to have 2 within a few years of each other (namely 2) and to note the differences. I had preconceived ideas as to what those were but i was sadly mistaken. They are without question different designs (or in the piano world ‘scales’) but what are the detailed differences?
I took a few measurements and i must admit they’re very similar in many respects. First thing i did was a measurement of the gram weight of the hammers. Exactly the same although they ARE stamped differently – is their density slightly different? I then measured the keys for balance point – the same. I was told that G’s didn’t have duplexing but both of these were exactly the same. Crossover was the same. I also measured the bridges and they were slightly different but not hugely (a 5mm difference). The only 2 areas of change that are notable: one is a cosmetic difference – a beveled lid on the C whereas the G is plain. Second and by far the biggest difference – the rim on the C is wider in the tail. What this means is that there are more square inches of soundboard – giving more vibration/volume. Interesting.
Playing the two pianos – if you didn’t have a point of comparison it would be next to impossible to tell. The major difference though from the player’s point of view is that the C ‘breathes’ a bit more. It feels somehow fuller and the sound seems a touch more ‘distant’. The G feels ‘close’. The tone appears to be right in front of you.
So there you have a brief and short comparison. Yes, you could pull apart every joint, every angle, every string gauge but the long and the short of the matter is that they’re both wonderful playing and sounding instruments and the changes are negligible.
