The shaman’s drum clearly is an instrument to bring forth a special trance, based on a mind empty of thoughts. In such an empty state, all shaman’s from the past, present and future can connect with the source of all creativity.
In this sample of a shaman’s drum song, the structure of thye song emerged from the void, without me doing anything but starting the drumming:

Also the reverse is true. By sitting and starting drumming in a monotonous way, you can slowly enter the no-though state. It is this state which supports the transpersonal wisdom, every-one has access to. You can access the transpersonal realm however, only when empty. That is why meditation on Shunyata, emptiness, is such an important tool for the shaman’s way.
