A corpus analysis of rock harmony [PDF] -
The analyses were encoded using a recursive notation, similar to a context-free grammar, allowing repeating sections to be encoded succinctly. The aggregate data was then subjected to a variety of statistical analyses. We examined the frequency of different chords

co-occurrence between chords, and changes in harmonic practice across time. More information, analysis, and explanation
here.

Dataists give their hopes and dreams for data, data tools and
data science in 2011.
Already, Google has provided
Google Refine (

visualizations can be created with online
tools or by combining R (great
posts previously), with
ggplot2,
GGobi, and even
Google Motion Charts With R (already built into Google
Spreadsheets).
Need data?
Needlebase, helps non-programmers scrape, harvest, merge, and data from the web. Or if you’re introspective,
Your Flowing Data and
Daytum provide tools to measure and chart details of your own life.
