The Uncertainty Principle is one of the milestones marking the break-up with former theories describing reality at macroscopic level. Its physical meaning has been deeply discussed and currently various approaches have not yet come to a common description. A didactic proposal, based on the acoustic analysis of a musical theme form the Steven Spielberg?s movie ?Close Encounters?, is proposed as a starting point to introduce, via analogy, the Heisenberg Principle to secondary school students. The ?Close Encounters? approach introduces the Principle as an intrinsic property of a quantum system, as something that holds regardless of any measurement process. Furthermore, it gives the possibility to carry out a discussion about the physical meaning of the Principle itself.
