Wait a minute
    If I want a soft sound do I want high partials or low fundamental and
"low harmonic development"  what ever that is. ?  I am taking you mean
"bright hammer" as a hard hammer.   How does a hard hammer give mostly
fundamental?

I don't understand the data below.  What is or are   "Vol units"  ?
