okay.so like the most extraordinary thing happened today while singing o magnum. it's around bar 24 where the basses come in with et admirabile then the rest of the sections echo after. ya la we held notes and ms ong was saying she heard an "extra" top note,which was a high "C".I heard it too!when ms ong pointed it out that is.hahahaha.freaky huh? it's an overtone [(; I did research!ahaha] the good news is everyone was using the same amount of energy and support.BUT our pitch not quite there yet T_T

composed a poem:
Stars a-twinkling
Lights are fading
Shadows are emerging
whispering
"the world is sleeping"

it is okay right? (:
