On a more personal level - although this arguably could be common in any type of group - is that what often inspires me is the excellent musicianship of my accompanist. We can really feed off the aural sound each of us creates. In terms of "visual" there is little there, just a person playing piano, and another playing solo double-bass. But, when we are at our best, there can be a real emotional impact on others simply from the sound we create.
