Am I even asking the right question? Perhaps I just want to know what 
relative humidity means.
Relative humidity is the amount of water vapor in the air, versus the amount 
it can hold, at a given temperature. If the temperature is, say, 70 degrees, 
and the air is holding all the moisture it possibly can, the RH is 100 percent. 
Since warm air holds more water than cold air, if the temperature then rises, 
the RH would go down, since the warmer air would be capable of holding more 
water.

Ambient humidity is just the relative humidity at a particular location, like 
in the living room where the piano sits.

         Also, what is the optimal humidity and temperature conditions for 
pianos?

1. Moderate and 2. Steady.
