Pianalyzer Voicing

[Roger Jolly]

Hi Mark,
             With out getting too detailed, the 1st, 2nd, 3rd, & 4th
Partial should approximate an exponential curve for amplitude. And be
better than 5 sec sustain time for each partial.
The true power and singing quality is really the RMS value of the sum of
the partials.
The lower register B3 down ward will tend to follow a more parabolic
evelope of partials. With the 3rd and 4th being the stronger.
Now throw in the personal perception of ideal tone, and we have a can of worms
Regards Roger
