Hip Hop and the LAPD

I was recently asked whether I had any data to support the claim that the number of mentions of the LAPD (Los Angeles Police Department) in hip hop lyrics has fallen off in recent years, after peaking in the mid-1990s. The LAPD attracted a lot of angry attention from hip hop artists in the wake of the 1992 LA riots, triggered when four LAPD officers were acquitted of using excessive force in the arrest and beating of Rodney King

Lute Music Analysis

I have recently exchanged a couple of emails with Jakob Hausladen, who has written a fascinating and enjoyable article on lute music, as part of a course on the philosophy of data science. The article draws on some of the techniques discussed on this site (including composers’ dates and nationalities, text analysis, publication network analysis), and also includes a section looking at a comparison of composers’ styles based on MIDI data. The article explains things well (including the risks and caveats), and makes excellent use of interactive graphics and sounds.

Like any good research, it raises lots of interesting questions for further investigation (some of which I have added to my list!)

I would recommend it for anybody interested in the use of statistics / data science to study music history. Or in lute music!
