Activity
The Influence of Latitude on Music
Grade Level: 6th to 8th; Type: Social Science
Objective:
This project compares music from several different countries to determine if there is a correlation between tempo and latitude.
Research Questions:
- Is there a weak correlation between tempo and latitude?
- Is there a strong correlation between tempo and latitude?
- Are there other factors like history or culture that could weigh in?
Materials:
- Internet access
- Pen or pencil
- Lab notebook
Experimental Procedure:
- Listen to 20 different national anthems from countries around the world. Click on this link to find a database of national anthems: http://www.nationalanthems.info/.
- Find the tempo, also known as the beats per minute (bpm), of each song. Do this by clapping out a beat for ten seconds and multiplying that number by six, or use the free music software listed in the references. Record each anthem's bpm in your notebook.
- Use the internet to research the latitude of each country.
- Graph each country's anthem's tempo and latitude on a scatter plot.
- Analyze your data. Was there a weak correlation? Was there a strong correlation? Were there any surprises?
- Could any other factors have affected the results?
Terms/Concepts: tempo, beats per minute (bpm), latitude, scatter plot, correlation
