I just bookmarked this article published today in Current Biology for later reading and annotation. While the article isn't specifically focused on memory, the fact that it touches on visual structures, emotion, music, and movement (dance) which are core to some peoples' memory toolkits, I thought that many here would find it to be of interest.

One of the authors provided the following tl;dr synopsis:

"Across the world, people express emotion through music and dance. But why do music and dance go together?

We tested a deceptively simple hypothesis: Music and movement are represented the same way in the brain."

For those who haven't integrated song or dance into their practices, searching around for the idea of songlines will give you some background on their possible uses.

This portends some interesting results with relation to mnemonics and particularly songlines and indigenous peoples' practices which integrate song, movement, and emotion.

Material sources: how might an individual have gripped the handle of this jug/balanced it on her head while walking a winding path, a rocky path, a forested path back to the village? What patterns would doing so have set up?

Or, how do you know what to look for, and do you know what to do when you see it?
