Statement of the Problem
Does the position of arms affect the way a
person will do a dance turn?
Project Overview
This project was to discover the most effective
arm position when doing a jazz turn.
A jazz turn is shown in the video below.
Research
Book- Dance Imagery for Technique and Performance.
This book helped with the way to do a proper jazz turn.
• Magazine- “Dance Star Magazine”
This magazine helped with the preparation of a jazz turn
• Interview- Mrs. Gia Waxman.
This interview helped us understand the basic information of turning.
• Website- http://www.fitforafeast.com/dance-lessons-pirouettes-pirouettetutorial.htm>
This was one of the many websites that helped us understand pirouettes and other
dance related topics.
Variables
 Independent variable: The position of arms.
 Dependent variable: The number of complete turns.
 Constants Variables:
 One ponytail in the back of the head.
 Same footwear on foot (left sock)
 Preparation of the jazz turn (fourth position)
 Plié.
 Turn to right.
 Knee in front of body.
 Repetition of the experiment in each position.
 Control group: Arms in the center position is the control group. This is
because it is the normal position used for turning and it gives more
momentum than the other positions.
Hypothesis
The positions of arms
at the center of the
body will be more
effective than the other
position because it will
have the greatest
number of turns in the
outcome.
Materials
 (1) Sock
 (5) Data Tables (One for Each Test
Subject )
 (1) Pen
 (5) Test Subjects
 (1) Recorder
 (1) Photographer
 (1) Camera
Procedure
 Step 1: Gather all materials.
 Step 2: Begin each test in fourth position. (Fourth position
is where there is one foot in front and one in the back,
about a shoulder-width apart. The back leg will come up to
knee height. More weight should be on the front foot
because it is necessary to push off with back leg. Also, to
measure each turn, the subject will begin facing forward.
Each time the subject faces front after one turn, it is one
complete turn.)
 Step 3: Turn as many turns as possible with arms center on
one foot.
Procedure (Continued)

Step 4: Record in notebook.
Step 5: Repeat with the arms center two more times.
Step 6: Record in notebook.
Step 7: Repeat steps 2-6 with the arms in fourth
position, fifth position, and with hands on the hips.
 Step 8: Create a data table.
 Step 9: Analyze and graph the results. Compare the
results.

Quantitative Data
arms in front of body
forming a circle.
 The Fifth position had arms
circle above the body.
 The Forth position had one
arm above head and one arm
in front of body, combining
fifth and center.
 The hip position had one
hand on each hip.
 Turning with arms in Center
position had a total of 26
complete turns .
 Turning with arms in Fifth
position had a total of 23
complete turns.
 Turning with arms in Fourth
position had a total of 21
complete turns.
 Turning with arms on hips
had a total of 23 compete
turns.
Conclusion
It was discovered that a person can do the most
amount of turns when the arms are in a center position.
This proves the hypothesis of “The position of arms at
the center of the body will be more effective than the
other positions because it will have the greatest
number of turns in the outcome” because the total
amount of turns in the center position was 26. This
number was the greatest result.
Possible Experimental Errors
 One possible error was the difference in height, age, and
experience. This height and age may have had an effect on the
experiment because of the differences in the test subjects. All
test subjects should be about the same height, age., weight.
Also, two of our subjects had prior dance experience. This
may have affected the results because they have had more
ability in turning.
 We tried to avoid these errors, but three of our test subjects
experiment.
Applications and
Recommendations
Applications
 Dancers use this in everyday
life. They need to know the
most effective way to turn
so they can do the most
amount of rotations in their
ability.
Recommendations
 For a future experiment, it
would be recommended to
use test subjects with the
same height, weight, age,
and experience. Using
similar test subject would
ensure proper results.
