The Effect Of Music Tempo on the Heart Rate of 7th Grade Girls

Researched by Crystal S.

Purpose

The purpose of this experiment was to find out what the effect of music is on the human heart rate of seventh grade girls. 

I became interested in this idea when I wondered how does music effect humans. 

The information gained from this experiment may help people find a more lively or relaxing music tempo.


Hypothesis

My hypothesis is that the slower the tempo the slower the heart rate will be. 

I base my hypothesis on R.M. Lonyears article in World Book Encyclopedia about "Music". He states that tempo makes the music seem more exciting. The heart beats faster when a person is scared or excited and slower when the person is relaxed according to Michael H. Crawford’s article in World Book Encyclopedia’s article about the "Heart."



Experiment design 

The constants in this study were: How long the subject rested before listening. How long subject listened. Same gender subject. Where the pulse was taken. Instrument listened to. Number of songs listened to. Same approximate age of subject.  How far away the subject sits from CD player. Same volume listened to. 

The manipulated variable was the tempo of the music. 

The responding variable was the heart rate. 

To measure the responding variable I took the radial pulse of the subject for 20 seconds. 



MATERIALS


QUANTITY ITEM DESCRIPTION
13 Subjects
1 Stopwatch
1 CD
1 CD player
1 Chair
1 Electronic pulse monitor




PROCEDURES

1. Obtain Permission slips from students.
2. Gather materials in test room.
3. Set up my CD player and test the volume.
4. Bring 1 subject to test room.
5. Let subjects rest for three minutes in a chair.
6. Take pulse.
7. Subject listens to music for three minutes.
8. Take radial pulse for 20 seconds and record.
9. Let rest 3 minutes.
10. Repeat steps 4-9 three times with different tempos of music.




 RESULTS

The original purpose of this experiment was to find out what the affect of music is on the human heart rate of seventh grade girls.

The results of the experiment were that the slower the tempo the slower the heart rate was.

See the table and graph below.



 CONCLUSION

My hypothesis was that the slower the tempo the slower the heart rate will be.

The results indicate that this hypothesis should be accepted. 

Because of the results of this experiment, I wonder if music would have affected 7th grade males different than females. 

If I were to conduct this project again I would have a larger sample size of subjects. I would also use a larger range of tempo variations.
