I don't know how I learned to do it (I can raise and lower my ears
independently of each other and I don't know how I learned that either)
but I know how to exercise the same muscles involved in swallowing WRT
my ears, without swallowing. It usually clears my ears in elevators
and aeroplanes.

After January, can we have a Truth and Reconciliation Commission?

Many years ago I took up drumming for the first few months I didn't use any
plugs and it left me with a ringing ear for about 8 months. The colour of
the sounds I heard would change in a pulsing manner as if I were plugging
and unplugging my ears. It faded away slowly. For me it was pretty obvious
what caused it, but still a good idea to see a doctor because a tumour might
also cause or exasperate it.

Less alarmingly, so might a virus, but you should get checked out in any
case.

The following link may be useful.
http://www.phys.unsw.edu.au/jw/hearing.html

I seem to be getting different results when I listen through speakers
and simply plug up one ear and match the pitch rather than using
headphones and putting one headphone cup against each ear at a time.

The difference, in the case of headphones is that the opposite ear
from the one hearing the pitch is unobstructed and so, in theory I'm
using the opposite ear to hear my voice to a greater extent compared
to the ear that being used to hear the pitch. If I'm listening to a
pitch with the headphone cup held up to my right ear and it is
perceived to be higher by my right ear, and then my left ear is
picking up more of my voice singing the note that it could cause me to
sing the note even sharper than if I were perceiving both the vocal
tone and the keyboard tone with the right ear alone.

Anyway, whatever is happening, something is off kilter with my right
ear, and if it doesn't clear itself up then I guess I'll have it
checked out at some point.

Pardon the top post. I suffer a similar (though worse) problem to yours.

This:

http://en.wikipedia.org/wiki/Musicophilia:_Tales_of_Music_and_the_Brain

is a great read and details others' similar problems and other, more bizarre
ones. Highly recommended.

In short, you're not alone.
