Music score alignment and computer accompaniment

Roger B. Dannenberg, Christopher Raphael
2006 Communications of the ACM  
Another way to predict spectra is to play the score through a music synthesizer and compute spectra from the resulting audio.  ...  Since the input in this example has 62 pitch estimates, consider all possible paths of length 62 through through the graph.  ...

A Hybrid Graphical Model For Aligning Polyphonic Audio With Musical Scores

Christopher Raphael
2004 Zenodo  
Each score position, in beats, would then be associated with the collection of pitches that sound until the next musical event.  ...  In interpreting this picture, the behavior of each variable (node in the graph) can be described given only its parents in the graph, e.g.  ...
