One of the key and unique components to The Elements of Rhythm series and its introduction of binary rhythm pattern theory is the way in which we classify and catalog the fundamental building block rhythm patterns. I recall showing the book draft to Peter Erskine several years ago, and one of the most important questions he could have asked me was, “What are you going to do with all of those 0/1 combination tables?” I told him I didn’t quite know yet but that I was sure there was an application that either myself or someone else would come up with.

Shortly after that conversation, I discovered some work by mathematician/musician Vi Hart, where she gave a presentation regarding a simple way to identify basic rhythm patterns using 0s and 1s. It seemed we were on a similar path, so I contacted her and asked how far she’d worked out her system. Vi replied that she had only down a little work, so I expanded on her idea and came up with the Binary Rhythm Pattern Indexing System.

The idea is that we can classify and catalog each of the fundamental building block rhythm patterns by their event point level grouping and the sequence in which they logically and naturally occur.

The Binary Rhythm Pattern Indexing System is important for several reasons. First and foremost, it doesn’t exist anywhere in music theory or rhythm research, at least not as far as I was able to find at the time I published The Elements of Rhythm in 2012. Secondly, it can be used by anyone who is interested in systematically researching rhythm patterns and wanting to somehow identify their fundamental essence.

It’s a system that’s in its infancy, waiting to be explored as a tool and modified as needed. For now, it can give you a basic idea of how to catalog and classify the basic patterns for up to eight event point levels (beat note groupings or beat note divisions). I hope it can prove to be of use in your work, and please feel free to submit comments on its use, application and improvement. My special thanks to Vi Hart for the inspiration to find meaning in the numbers. She’s amazing in that way, and I invite you to explore her own works further, at
