# digmus

![](outputs/plots-tabs/melody_graph.jpg)

An experimentation with animating a melody as a graph.

## Unsolved problem

Including a self loop on the graph gets the timing right, however, the first edge is dropped.

## Code

See [step-by-step](https://github.com/softloud/digmus/tree/main/step-by-step) for each step of the process, from wranging midi, to plotting a graph, to animation. 

## Outputs 

Written to outputs/, but not all files are there as some of the intermediary files are too large to push to Git.
