Funny how listening isn't really taught in music.
In some cases we are taught the importance of 'playing the silence', but not much more.
Musicians generally learn/absorb the importance of listening as the years go by, and also learn to listen and play at the same time.
If we are really lucky we can export this 'tool' into our daily lives and appreciate the importance of listening in general.
As a musician I understand that the 'better' I listen the more secure and focused I am when I have to 'talk/play/communicate in any situation. If people are able to appreciate how empowered they become just by listening then they have a good reason to adopt the habit....maybe
Of course a good acoustic space will enhance this and enable people to actually hear what is being said...always an advantage
