[pianotech] question about agraffes and uprights

[Susan Kline]

Hi, Duaine

I think it's because agraffes were necessary on grands to
hold down the strings when the hammers strike up at them.
The capo bar does the same thing, so on some cheap grands
the whole tenor has a capo bar.

On uprights, the hammers strike toward the bearings, so
the strings aren't lifted off them, so the support isn't needed.
