## Background
FIELD OF THE INVENTION
The present invention relates to a method and system of dance instruction. In particular, the invention relates to a method of using lights and a light system for teaching dance.
BACKGROUND OF THE INVENTION
Dancing is a very popular entertainment and art form that requires the dancers to learn various steps of a particular style of dance. Dance is a multifaceted area of study which provides the student with opportunities to experience the physical, mental, and emotional challenges of disciplined movement.
Children are often introduced to dance at a very young age, sometimes as early as two years old. An important aspect of any type of dance is developing the proper form and the right body position. The benefits of dance to students are numerous and include improvement in motor proficiency, skill accomplishment, balance, fitness, body awareness and posture, as well as discipline, physical satisfaction, emotional release, a sense of camaraderie, and a higher appreciation for the arts. Potential for self-actualization is developed and feelings of self-worth may be increased.
Dance teachers typically use music and oral instructions in teaching dance to students. The music assists dancers in letting them know where they are supposed to be in the dance. However, such methods of instruction fail to effectively teach dance to students who are deaf, tone-deaf, and/or hard of hearing. Often such a dancer will use his or her eyes to watch and follow the movement of a fellow dancer who may be able to hear and follow the music. This often leads to frustration at the deaf student's lack of progress and he or she may lose interest, thereby not enjoying any of the benefits associated with dancing as a result of his or her hearing disability.
There is a need to effectively teach dance to deaf students or to those who are unable to hear and follow music. In particular, there is a need for a method of dance instruction that will provide deaf students with a sign count for each step in order to help them establish a basic rhythm pattern and develop the inner rhythm and timing for a particular dance.
U.S. Patent Application US 2006/0154220 filed Jul. 11, 2003, by Toniolo, discloses a training device for novice/professional dancers. The device includes a mat with foot positions, and a video recording system and display that show the dancers what they are doing along with textual feedback. The focus is on fundamental foot position, and also teaches the use of signs or indicators on a screen. Such a device allows students, including visually impaired students, to determine the correct position of their feet and body during dance. The device taught by Toniolo could be used by deaf students to determine correct positioning. However, it would have the same advantages and disadvantages as watching and following the movements of a fellow dancer, and thereby lead to frustration and loss of interest.
Consequently, a need exists to effectively teach dance to deaf students to or others who learn more effectively through visual display to enable them to enjoy the benefits thereof.
SUMMARY OF THE INVENTION
The present invention relates to a system and method of dance instruction wherein visual display configurations which are preferably lights are used to signal visual time signature.
The present invention employs the flashing of lights on a light bar or at least two light bars in specific configurations to represent specific movements and rhythms and sychronizations therefor.

DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention relates to a system and method of dance instruction. As shown in FIG. 1A, an apparatus 10 is provided for implementing the system and carrying out the method of dance instruction. The apparatus preferably includes a first light bar 12 and a second light bar 18. In the preferred embodiment, the first light bar 12 is horizontal and the second light bar 18 is vertical. The first light bar 12 and the second light bar 18 are preferably connected. The connection is preferably such that the first and second light bars form the shape of a cross, as shown in FIG. 1A. However other connection configurations such as a T-shape are within the scope of the present invention.
The present invention is also not limited to the first and second light bars being horizontal or vertical or otherwise straight in shape. The first and second light bars may be curved, for example, and may have various other shapes and designs. In addition, in alternate embodiments, the first and second light bars need not be connected. FIGS. 1B and 1C show alternate embodiments where the first and second light bars are not connected.
Although it is preferred to carry out the present invention with the apparatus 10 having both the first light bar 12 and the second light bar 18, the present invention may be carried by operating either the first light bar 12 in isolation, as shown in FIG. 1B or the second bar 18 in isolation, as shown in FIG. 1C.
The first light bar 12 includes a plurality of first lights 14 and a plurality of second lights 16. In the preferred embodiment, the first light bar 12 has four first lights 14 and four second lights 16. In alternate embodiments, the first light bar 12 may have either more or less than four first lights 14 and may have either more or less four second lights 16. Similarly, second light bar 18 has a plurality of first lights 20 and a plurality of second lights 22. In the preferred embodiment, the second light bar 18 has four first lights 20 and four second lights 22. In alternate embodiments, the second light bar 18 may have either more or less than four first lights 20 and may have either more or less four second lights 22. In addition, in alternate embodiments the number of first lights 14 and second lights 16 on the first light bar 12 need not be the same. Similarly, the number of first lights 20 and second lights 22 on the second light bar 18 need not be the same.
The first lights 14 are visually distinguishable from the second lights 16. Similarly, first lights 20 are visually distinguishable from the second lights 22. In the preferred embodiment, the second lights 16 are smaller than the first lights 14 and similarly, the second lights 22 are smaller than the first lights 20. Other modes of visually distinguishing the lights known in the art are within the scope of the present invention such as the use of different colours, tones, shapes, size, etc.
The first lights 14, 20 and the second lights 16, 22 of the first light bar 12 and the second light bar 18 are preferably lights which can be seen in all areas of a studio or stage so that deaf and/or hearing impaired dancers can understand the differences in tempo without having to look directly at the lights. When a single light in a normally lit room is turned off and on, a person is able to see the effect of the light anywhere in the room. Any of the first lights 14, 20 or the second lights 16, 22 of the first light bar 12 and the second light bar 18 may also be coloured to accent and/or specify beat in bar music.
The first lights 14, 20 and the second lights 16, 22 of the first light bar 12 and the second light bar 18 preferably use gel, which assists with the prevention of glare and stops the lights from shining onto the stage.
The light system also includes a control unit (not shown) for a) turning the plurality of first lights 14, 20 of the first light bar 12 and the second light bar 18 on and off to display a pre-selected time signature pattern; and b) turning the plurality of second lights 16, 22 of the first light bar 12 and the second light bar 18 on and off to display a pre-selected and count time signature pattern. The control unit is also adapted to select the colour that each individual light will flash depending on the programming for the individual movement.
A control unit (not shown) is operatively connected to the apparatus 10. The control unit can be programmed to turn at least one of the plurality of first lights 14 of the first light bar 12 and first lights 20 of the second light bar 18 on and off to display a pre-selected pattern representing a pre-selected exercise, as shown in FIGS. 2A and 2B. Several pre-selected light patterns corresponding to pre-selected exercises can be programmed into the control unit.
The control unit of the system is preferably a computer and preferably has software programmed to produce predetermined musical time signature (2/4, 3/4, 4/4) so that they represent their musical value visually. The software can be designed with the ability to alter the speed of the lights and the colour of the light to be flashed. The sequence of time signatures can be linked together for individual choreographic works which contain more than one time signature. The software is preferably run through a special computer module which is hooked up to a computer interface. The computer interface preferably uses the information from the software program to control the first lights 14, 20 and second lights 16, 22 that are seen by the dancers. The first lights 14, 20 and second lights 16, 22 on the first light bar and the second light bar are preferably connected to the computer interface by long cables to allow each bar to be mounted in separated locations.
A preferred embodiment of the method of dance instruction of the present invention involves turning the plurality of first lights 14, 20 of the first light bar 12 and the second light bar 18 on and off to display a pre-selected time signature pattern, and turning on and off the plurality of second lights 16, to display a pre-selected “and” count time signature pattern. The second lights can also represent a whole beat. In addition, the method also includes the step of turning at least one of the plurality of the first lights 14 of the first light bar 12 and the plurality of first lights 20 of the second light bar 18 on and off to display a pre-selected pattern representing a pre-selected exercise.
The pre-selected “and” count time signature pattern of the method and light system of the present invention are preferably in synchronization with music.
The first lights 14, 20 visually represent the musical value. As shown in the first light bar 12 in FIGS. 2A and 2B, in a 2/4 time signature, the first two first lights 14, 20 will turn on and off separately and continuously. In step one, as shown in FIG. 2A, the first of the first lights 14 will turn on while the remaining first lights 14 stay off. In step two, as shown in FIG. 2B, the second of first lights 14 turns on while the remaining first lights 14 stay off. This 1-2-1-2 pattern represents a 2/4 time signature. The pattern for a 3/4 time signature is 1-2-3-1-2-3. pattern for a 4/4 time signature is 1-2-3-4-1-2-3-4.
FIG. 3 shows the second lights 16 on the first light bar 12. Preferably, the second lights 16 display the “and” count. This can be done in a 4/4 pattern. Similarly, the second lights 22 on the second light bar 20 are used to 16 display the “and” count which can also be done in a 4/4 pattern.
Oscillating first lights 14, 20 can be used in the first light bar 12 or the second light bar 18 or both to demonstrate examples of specific dance movements. For example, FIGS. 4A, 4B, 4C, 4D, 4E and 4F demonstrate a “plie”, which is a classical ballet exercise. As shown in the embodiment in FIGS. 4A, 4B and 4C, the oscillating first lights 14, 20 can be used to teach the “legs bend” aspect of the plie, and as shown in FIGS. 4D, 4E and 4F, the oscillating lights can also show the “legs straighten” aspect of the plie. The dancer need not count the beats, but simply follow the lights down and up.
Another ballet exercise, the “battement tendu”, can also be taught by using the oscillating lights of the present invention. FIGS. 5A, 5B, 5C and 5D demonstrate a “battement tendu” outwardly, and FIGS. 5E, 5F, 5G and 5H demonstrate the leg closing to a 1st or 5th position. The oscillating lights have a 1, 2, 3, 4, 4, 3, 2, 1 sequence of first lights 14 on a horizontal light bar 12.
FIGS. 6A, 6B, 6C and 6D show the first light bar 12 displaying a pattern representing inner and outer leg positions. The set of instructions represented by these figures can be used to instruct a two echappé sauté movement in centre practice. For example, the centre second light 50 can be flashed four times in yellow to instruct a 4/4 one bar introduction. FIG. 6A represents beat one which is a sauté to second position. FIG. 6B represents beat two which is a sauté to second position. FIG. 6C represents beat three being a sauté to second position. FIG. 6D is beat 4 which is a sauté to first position.
As shown in FIGS. 7A, 7B, 7C and 7D, all light formations that can be displayed on the first light bar 12 can also be displayed on the second light bar 18.
The light system of the present invention can be implemented in a multitude of different manners given numerous permutations and combinations of light representations that are possible. These possible combinations are increased by the fact that each individual light can flash a variety of different colours. Each different colour can represent a different movement or instruction.
One example of the possibilities that exist is demonstrated by FIG. 8 which represents a method of displaying introduction instructions in centre practice. In this example, the first lights 14 of the first light bar 12 are adapted to flash yellow light. The first lights 14 can flash 2/4, 3/4 or 4/4 time signatures to represent specific introduction movements. Alternatively, a centre second light 50 can flash in yellow or any other colour to represent beats of a bar of music to represent an introductions. It is preferred to use the centre second light 50 for the display of the introduction. However, a person skilled in the art will appreciate that any of the other second lights can be used for this purpose.
The use of different coloured lights can be used to represent different movements. For example, for instructions representing an en dehors and en dedans movement, one coloured light can be flashed to represent movements away from the supporting leg while a different coloured light can be used can be used to represent movements toward the supporting leg. FIG. 9 shows an example of the implementation of this type of set of instructions. The first lights 14 of the first 12 and second 14 light bars are adapted to flash either blue or red. Movements away from the supporting leg (en dedors) are represented with a blue light while movements toward the supporting leg (en dedans) are represented with a red light. One of the first light can be adapted to also flash a an additional colour such as yellow to represent to position of the supporting leg at the bane and depending on the location of the first light flashed along the horizontal bane, it can be demonstrated whether the right leg or the left leg is the supporting leg. Alternatively, the colour of the first light flashed can represent which leg is supposed to be the supporting leg. In this particular example, the centre second light 50 can be flashed to represent closed first or fifth position.
FIG. 10 shows another example of how the present system can employ different coloured lights to represent different movements. In this implementation of the system, contrasting lights colours are used to show over and under movements travelling from side to side using the first light bar 12. The colour representing a specific movement ends where the working leg finishes.
For example, the lights can be adapted to flash either blue or red. For an assemble dessus movement (over), the first lights 14 on the first light bar 12 flash from red to blue. In an assemble dessous or under movement, the first lights 14 on the first light bar 12 are flashed from blue to red.
The second bar 18 can be used for representing movements that require moving forward or backwards. For example an en avant or forward movement is represented by flashing the first lights 20 on the second light bar 18 from red to blue. An en arrière movement is represented by flashing the first lights 20 on the second light bar 18 from blue to red.
As shown in FIG. 11, the use of contrasting colours can be used to accent a beat. In FIG. 11, first lights 80 flashes blue while first lights 82 and 84 flash red. Hence in the one bar 3/4 beat, the blue light accents the first beat of the bar.
The present system is also used to represent oscillation movements. FIG. 12 shows two first bars 12 with a 4/4 time signature. The lights flash on and off in succession such that four beats outward are represented and four beats inward are represented. This can represent tendu side and close fifth position.
FIG. 13 shows an alternate manner of representing the same oscillation movement as is shown in FIG. 12. In this expression of the movement, the lights come on in succession to form a line of light with four beats outward and four beats inward.
FIG. 14 shows an oscillation movement using two second light bars 18. In this instance, the oscillation movement is demonstrated with the two second light bars 18 having a 3/4 time signature. Plié is represented with three beats and stretch is represented with three beats.
FIG. 15 shows an implementation of the system using two vertical second light bars 18 with a 2/4 time signature. Light 88 represents a dancer in air while light 90 represents a dancer in plié. The frequency of the oscillation can be used to represent jumps, hops, skips and/or gallops.
The system of the present invention also represents instructions through the differentiation of light. The duration of each light's illumination communicates the quality of that note. For example, a short flash could indicate staccato. A longer flash could indicate legato.
