Music Music is an extremely valuable asset on the street. Assuming it is the right kind and is done in the right manner, music builds an instant rapport and sets the hearers up for the message. An instrument of almost any kind can be used. Some are better than others. Guitars do not project well and have some bad associations.
Trumpets are difficuit to sing to, but are attention getters.
Abrass band would be great, but not many of us have ready access to them. The best instrument that I have found is an accordion. Everyone has a good remembrance associated with an accordion, and it projects well and is good to sing with. Get as many people singing as you can. Several songs are in order before the preaching commences.
