Need a program for science fair
 

For this year's science fair project, I'm trying to make frequency graphs of certain frequencies in popular songs, and am going to compare them to see if music of same genre have similar frequency characteristics. To do this, I need a program that can take a certain frequency, and graph its changes over the entire song. This would be preferably for seven or eight different frequencies. Thanks.

Simulink - Simulation and Model-Based Design

Closest thing I can think of, but it's on the science side of things, not music. Comes with frequency spectra & dynamic modeling scripts to monitor that sort of thing. But honestly, by the time you figure out how to implement it for your intended use you might as well design your own program.

By the way, that sort of thing falls under the umbrella of "signal processing."
