Abstract or Description

• Do beats per minute in music affect heart rate?
• We hope to discover how bpm in music affects heart rate
• Our independent variable is beats per minute in music 
• Our dependent variable is heart rate
• Our hypothesis is: If beats per minute are related to heart rate then an increase in song bpm will cause an increase in heart rate because when humans are listening to a song with high beats per minute the parasympathetic nervous system increases the heart rate.

Materials and methods

1. Pulse oximeter 
2. Apple computer 
3. Beats Mixr
4. Human participants (10)
5. Quiet room
6. Script 
7. Song 1(You Really Got Me (2015 Remaster))(137 bpm)
8. Song 2 (Crazy In Love - Beyoncé ft. JAY Z (Lyrics) 🎵) (99 bpm)
9. Song 3 (The Tokens - The Lion Sleeps Tonight (Wimoweh) (Audio)) (60 bpm)

1. Gather materials
2. Take participants into study room
3. Read script
4. take the participant's heart rate
5. Have participants listen to song 1
6. Take the participant's heart rate
7. Repeat steps 3-6 with song 2 and song 3
8. Repeat steps 1-7 with different participants
9. Analyze data 
10. Conclude experiment

Constants

• Pulse oximeter 
• The lion sleeps tonight- The Tokens (60 bpm)
• Crazy in love- Beyonce ft. JAY Z (99 bpm)
• You really got me- Van Halen (137 bpm)
• Participants with pieces 1, 2 and 3
• Volume (50%)
• The participant is sitting the whole time 
• Time in between songs (30 seconds)
• Headphones (beats solo3)
• Directions to participant
• Script
• Same order the songs are played (You really got me- Van Halen, You really got me- Van Halen, The lion sleeps tonight- The Tokens)

Trends 

In this experiment we found that the higher beats per minute song the higher the participants heart rate went up. In the averages in this experiment we found that in song 1 (You really got me going-Van Halen (137 bpm) the participants heart rate went up an average of 2.25 heart rate. In the participants heart rate for song 2 (Crazy in love- Beyonce ft. JAY Z (99 bpm) we found that the participants heart rate decreased an average of 7.625 beats per minute. The average heart rate for song 3 (The lion sleeps tonight- The Tokens (60 bpm) set the participants heart rate up .125 heart rate. This supports our hypothesis. Our findings can be helpful in the future because it can show people that you can manipulate people's heart rate with music.
