Same Events For example, the sound of thunder during the forest walk for many associated with mixed feelings about the possibility of get wet from rain, and someone - on the contrary, with joy over the possibility of a bath. Some sound events may have persistent and unpredictable associations. If a certain song or melody was played earlier in the events that cause pleasant memories, re-listening to songs will also cause a pleasant association. If the same melody is associated with tragic events, it re-audition did not bring sorrow and grief but. According to this, using known songs, you can call or cause stable association as one individual, and the masses. Playing a combination of different objects creates a completely new sounds.
