If it was simply a musical note, I would probably be able to characterize it in terms of its pitch (i.e., perceived frequency) and duration and possibly its dynamics but, I think it is something that goes far beyond our concept of a note.
An explanation would only be mired in the lexicon of a musical theory that was construed in the ivory towers of academic institutions inhabited by nonbelievers blinded by their own arrogance.
The Am truly transcends our mere mortal concept of a note and to advance this community we must accept the Am and strive to obtain oneness with it. Our time here is fleeting and should not be wasted in attempts to shackle the Am and subject it scientific analysis.
