Michael,

you worked a lot on Fourier. So you obviously know more
than I do. Surely you are joking.

Will a lighter hammer produce more attack noise?
Less loudness, brighter sound?
After a time the string will have ist characteristic movement. (Your
words).Would the sound be different in the beginning? How long is the time
span?

Helmut,

No I wasn't joking.  Just because I studied it for six months doesn't mean
I grasp it.  I take the squirrel approach most often and especially in the
case of Fourier Analysis.

For example, I feel like I ought to be able to answer this question: Will a
hard blow from a hammer produce a tone which sustains longer than that of a
soft blow?  Some questions that are sort of analogous.  I have two pennies
one penny is five times as hot as the other when I begin to monitor their
temperatures. Both of these pennies are in a bath which is constantly taking
away their heat energy in a way which does not change the temperature of the
bath. I monitor the temperatures until equilibrium occurs between the penny
and the bath.  Which penny will arrive at the equilibrium temperature first?

Next question: I have two ice cubes, one is removed from a freezer with a
temperature of 0 c, the other is removed at the same time from a freezer with a
temperature of  -15 c.  These cubes appear to be identical in shape and they
are the same mass.  Which ice cube will melt completely first?

By the way, where do you live?
