Thought Mechanics

Can "Moonlight Sonata" be played on piano or organ, or both? Regardless of the instrument, is the composition not the same? Or at the very least, does the composition not hold the same essence from instrument to instrument? If your answer is yes, then you must concede there is something to be abstracted. Do ideas not dance on the strings of the brain? Why then can the music of the mind not play on a different instrument?
