But with Music21, we can actually look at distribution of interval uses by a year, by decade or over a long period of time. So now can we see these evolutions over time where we can pick out a few representative pieces and do it by hand. And then we have a period with a lot of moving down by thirds, and now we're in a period of a lot of moving up by thirds or things like that. There used to be a period where all the baselines, you know, classical music, tended to have a lot of jumping around that we call fourths and fifths. Myke: One of the things that we looked at is how the baselines of pop songs change over time. Host: What's an example of one of those analyses the musicologists might be interested in? LILYPOND TUTORIAL PROFESSIONALThe Music21 motto is ìListen Faster,î so it allows you to do the types of analytical procedures that people who are really interested music, professional musicologists, do all the time, but between a thousand and a million times faster than we can do it by hand. Then, we can use this to analyze large quantities of music or make comparisons across different musical genres or times and places. It's primarily focused on symbolic music - things like music theory ideas, chords, keys, scales and rhythms - that can be precisely represented in a computational framework. Myke: Music21 is a library of modules for being able to represent music and manipulate it. Host: I've been looking forward to this, because I've started playing around with Music21, and I'm excited to hear your own perspective and get some further details. In addition to his lectures and writing on music, he is also the primary investigator of the Music21 project, a Python library for flexible, computer-aided musicology analysis. His scholarship and research explores medieval music as well as minimalism. Host: Michael Cuthbert has a PhD in musicology from Harvard and is presently associate professor of music at MIT.
