What is the function of the bellows in an accordion?

Accordion bellows are the concertinaed section in the center of an accordion. The bellows are expanded and contracted to pass air through various metal reeds inside the instrument that are responsible for the generation of noise. An accordion will not make any sound unless the bellows are contracted or expanded.

What does pulling the bellows allow you to control?

As you operate the bellows you are directly connecting with the reeds of the instrument, so are directly able to continuously control the sound in a truly exciting manner. This is a lot more than making enough noise!
