[pianotech] 4ths 5ths

[Ryan Sowers]

Marshal,

Yes I do! On some spinet pianos the thirds start out slow, and progress very
slowly. It is not unusual for thirds to actually slow down as you move up
the keyboard once you leave the wound strings and are totally on the plain
wire. The high inharmonicity of those low plain wires, sharpens the partials
make the thirds sound more contracted than usual. Also the 6:4 5ths will be
annoyingly fast for the same reasons.
