Transcript Math and Dance Related?

Dance is defined
as: to move one's
feet or body, or
both, rhythmically
in a pattern of step,
especially to music.
Do you know
that every time
you dance, you
are doing math?
Dancing is moving
your body at the
rythm of the music.
Rythm involves
patterns and patterns
are MATHEMATICS!
Dance and Math
How is dance related to math?
Rhythm (counting beats)
Dance can be related to the timing of the beat,
the number of steps involved in a dance move,
the number of parttners involved,
the number of instruments that it takes to play
the music,
the number of choreographers that it took to work
out the dance move, etc..
Form
Geometry of lines:
Dance requires you to make
different shapes and angles
with your body.
Using symmetry
to form formations
Geometry
Dance movement can be all sorts of combinations of
circles, points, angles and lines
So there are plenty of ways that we can physically
experience (or watch) geometry.
All the topics included in dance are:
Shapes:
Dancers are constantly making shapes
with their entire bodies. They form
simple shapes with their arms and
legs such as circles, triangles and
lines as well as more complex shapes.
Dancers also make different shapes
with their formations.
Patterns:
Everything in dance has to do with
patterns. Dancers memorize patterns
in the steps in their dances. Music
usually has a pattern of verse-chorusverse-chorus that dictate a dancers
movement. They also follow a pattern
in the music, counting 1-8 over and
over.
Parallel Lines:
Dancers often have to think about
staying parallel to other dancers to
preserve formations. They need to keep
the same distance between themselves
and the other dancers no matter how
they move.
Circles:
This could be as simple as ronde
de jambe, or as fluid as all the
circles necessary to keep
movement smooth.
Angles:
Dancers need to focus on the angles
they make with their bodies to
form the correct shapes.
These dancers are making right angles with their
bodies. You can find the degrees of the angles of their
bodies.
This dancer is making a 180° angle with her leg. The
slope of her line is undefined.
The term
is called
Penche.
This dancer is making a 90° angle with her leg.
This term is
called
Arabesque
The slope of his line is 0. His arm is making a curved
line.
This term
is called
a Grand
Jete
This dancer's leg in making a scalene triangle. Her
arms are also making a straight line on an angle.
This term
is called
Passe.
Tutting
Tutting is a style of
dance that is based
totally on geometry
and patterns and
angles, mosty with
your arms.
Hip hop brought a
style of pop locking
that involves
geometrical
movements to form
90 degree angles.
This is such a sick
style of dance when
it's done right. It's
pretty crazy how
dope it looks.
Symmetry
o
o
Dance can also be very symmetrical.
Dancers are constantly moving their
bodies across the stage so that it reflects
the same consistent pattern.
Often, formations in a dance create
reflection or rotational symmetry. Also,
partner dancing often uses both reflection
and rotational symmetry.
The two
ballerinas are
creating
reflection
symmetry,
with the line
of symmetry
drawn in pink
The girls are
illustrating
rotational
symmetry,
with the point
of rotation in
the middle of
the circle as
well as
reflection
symmetry.
Dancers also have reflection
symmetry in their own bodies.
The first two images are symmetrical;
the third is asymmetrical.
