Generating Music using Markov Chains

In a nutshell, Markov chains are mathematical systems that track the probabilities of state transitions. They're often used to model complex systems and predict behavior. They're used in a lot commercial applications, from text autocomplete to Google's PageRank algorithm. My first encounter with a Markov chain was actually in my high school software development class when a classmate built a chat bot using this concept. He took the log from our class Slack chat and fed it into a Markov chain.
