Dance form analysis
|
|
|
|
|
1. Dance segmentation |
|
2. Connections between
structural units |
|
3. Unit classification |
|
4. Representative form of a
unit class |
|
5. Unit naming |
|
6. Written dance
representation |
|
7. Mistakes of the dancer |
Formal methods
|
|
|
|
|
Formal method: works only with
notation |
|
i.e. with written graphical
signs without any meaning. |
|
|
|
|
|
Since formal methods will be
dependent upon the quality of notation, |
|
i.e. how detailed and
graphically standardized it is, notation |
|
conventions have to be complied
with before performing an analysis. |
|
|
Concepts I.
|
|
|
|
|
semantic equality |
|
(identical movement) |
|
|
|
syntactic equality |
|
(identical symbols) |
|
|
|
graphic equality |
|
(identical drawing) |
|
|
Concepts II.
|
|
|
|
|
Laban-pattern |
|
|
|
matching |
|
- strong match |
|
(sign-length-identical) |
|
|
|
- weak match |
|
(sign-length tolerant) |
|
|
|
- very weak match |
|
(sign-length and pre-sign tolerant) |
|
|
Concepts III.
|
|
|
symmetric Laban-pattern |
|
augmented Laban-pattern |
|
wildcard Laban-pattern |
|
Laban logical expression |
Applying formal methods
1.
|
|
|
matches: the longest sequences on
measure-starts avoid variants |
Applying formal methods
2.
|
|
|
a query, search parameters and isolated
occurrences |
Applying formal methods
3.
|
|
|
skipped linkers, found variants, recognized
mistakes |
Applying formal methods
4.
|
|
|
dance element instances and composed schemas |
Applying formal methods
5.
|
|
|
measure-start segments and their connections |
Summary
Summary (cont.)
|
|
|
Having formal concepts and
methods |
|
could facilitate dialogue
between researchers |
|
on a higher level of
objectivity |
|
is necessary to describe
algorithms |
|
for computer-aided dance
analysis. |
