Sound, all around us continually. So much so that when there is none, it is most noticed! Certain intonations can catapult us in to a particular state, individually very personal. The background music we choose, either assists the mood we are in or, tries to change our mood to a more preferred state.
A particular set of notes or sounds can remind us of times gone by, or where we want to be? It is good to have some control of our surroundings, to make the best use of our time. Carry around with you a Calling Bell, as a permanent reminder.
Trigger - The Sound of Silence.
