Chemistry lyrics

Signals transmitted
Message received
Reaction making impact --
Invisibly

Elemental telepathy
Exchange of energy
Reaction making contact --
Mysteriously

Eye to I
Reaction burning hotter
Two to one
Reflection on the water
H to O
No flow without the other
Oh but how
Do they make contact
With one another?
[ Lyrics from: http://www.lyricsmode.com/lyrics/r/rush/chemistry.html ]
Electricity? Biology?
Seems to me it's Chemistry

Emotion transmitted
Emotion received
Music in the abstract --
Positively

Elemental empathy
A change of synergy
Music making contact --
Naturally

One, two, three --
Add without subtraction
Sound on sound
Multiplied reaction
H to O
No flow without the other
Oh but how
Do we make contact
With one another?
