So piano playing? If I bathe my rhododendron in nitrous oxide, it stops producing oxygen. Filling my plumbing with nitrous oxide causes my toilet flushes to stop working.
Bigfoot is what you see in this photo here [0]. A useful phenomenological description doesn't presume and use the thing it attempts to describe.
A good definition would look like the Mirror Self-Recognition Test (MSRT), or even simple verbal affirmations of personal consciousness, or some MRI features, etc. But these all have glaring limitations.
MRST is unusable with blind patients, it only tests a specific kind of awareness, and it turns out that toddlers fail the test.
Verbal affirmations limit coverage to socially functional, speaking humans, so severe autistics fail, and duct tape over the mouth (or aphasia etc.) presumably impairs consciousness as well.
MRI brain features seem to always disappoint with obvious flaws like above or have some crazy exceptions of some living, healthy patients who are missing parts of their brain.
Until we can talk about consciousness without saying "consciousness" or referring to it indirectly, then we're just hallucinating IMHO.
