Abstract :
Explores the topic of perception, using the dance of the Tango, as a metaphor to explain how a complex set of music, instruments, and human emotions and experiences can be used by bioengineers to design and create new forms of technology to benefit mankind. How our central nervous system (CNS) decides that a given combination of sounds causes pleasure or not is a question with no definite answer yet and is not the intended subject herein. This column only aims at showing how the tango, a tiny subset of the overall musical world, followed a path since its inception in the 1870s or 1880s that moved from rather simple consonant melodies to highly elaborated compositions rich in all sort of well-handled consonant???dissonant combinations, many cadences to give musical phrases a distinctive ending or a sense of conclusion, adequate key conversions or shifts, including rhythmic changes or even lack of rhythm.
