• Why do those grieving and those enjoying themselves like listening to the flute?
Seemingly the former to grieve less,
the latter to increase enjoyment.
• Why is it that, the sound travels farther when the same person using the same vocal power,
singing or shouting with others, than when alone?
Because doing something together,
like compressing or pushing,
isn't an effect proportional to their number,
but as a two feet long line
writes not the double but quadruple (that of a 1 ft line)
so composites have greater power, relative to their number
than when taken separately.
Thus, when more people sing,
the voice power unites
and impels the air simultaneously,
so that it travels manifold farther;
for the voice produced by all
is the multiple of each single voice.
• Why does the voice waver the most when singing the note "parhypate"
and not less than when singing the "nete" and higher,
although the interval is higher?
Is it because this note is hardest to sing and it is a primary element?
Hard due to straining and pressure on the voice;
And these require effort;
And things requiring effort are more likely to fail.
