Re: Reed sound, where does it come from?

It's not the vibrating reed itself that makes the sound, not in the same
manner as a vibrating surface such as an acoustic guitar top or loudspeaker
(the reed is much too tiny for this to be effective).  It's that it's
chopping the air flowing through the reed slot, and to a large extent this
chopped air vibrating the air inside our mouths and respiratory systems.  A
resonant player will therefore have a *much* louder and fuller sound, just
as a set of vibes sounds much fuller and fatter than a xylophone (the
vibraphone has resonators under each bar.

BTW plinking the reed is probably not the best way to tune a harp.  I find
that the pitch tends to be somewhat different when I play or plink.  Get a
couple of clamps to hold the reeds and comb together, then play the note to
check tuning.
