Balinese Dance Music, Rhythm, and Trance State Group 1: Alicia, Fred, Javier Monday, June 4, 2007 Balinese Dance Group 1 Alicia OVERVIEW: 1. History and Culture of Balinese DanceAlicia 2. Anthropological Studies and The Hypnotic Trance 3. Neurophysiology of Dance – Fred 4. The Induction of Trance – Javier 5. Long Term Effects of Dance 6. Discussion - All Balinese Dance Group 1 Alicia History of Balinese Dance • Indigenous originī combination of MalayoPolynesian ancestor worship culture of a 25001000 BC migration to Bali and more modern Hindu-Javanese elements (prior to 14th century AD) • Dance as religion->ancestor worship as well as ritual blessings offered to gods • Children begin dance education/school from walking Balinese Dance Group 1 Alicia The Purpose of the Dance • Educating the Community: Story-telling of tradition and cultural values -Balance of Good and Evil -Gender Roles/Identity -Cultivating control of the self (body and emotions) • Communion With the Gods – Possession and Trance Balinese Dance Group 1 Alicia Hypnotic Trance • • Anthropological Studies of Margaret Mead Analysis of Trance by Erickson: • • • • • Absorption in dance Unified movement of the body Increased muscle tone/rigidity Minimum use of energy Additional Parallels to Hypnosis • • Amnesia Unusual Physical Feats: Kris Dance Balinese Dance Group 1 Alicia The Character of the Dance • Primary Musical Instrument: Percussion • Training of specific types of coordinated movements: arms, hands, legs, shoulders, eyes • Rhythmic movement on time with drum • Controlled Eye Movements • ???How do these potentially induce trance???

Swinging in the brain: shared neural substrates for behaviors related to sequencing and music. Volume 6 Number 7 July 2003 Nature Neuroscience Balinese Dance Group 1 Fred Behavior and Dance: Timing … • Metric Condition: – requires perception and production • Non-metric Condition – require explicit memory • “… rhythmic properties of a piece of music entrain neural oscillators that facilitate synchronization of both perception and action with the underlying beat in music.” (9,10) Balinese Dance Group 1 Fred Behavior and Dance: … and sequencing • Serial Reaction Task (SRT) • Outside temporal context • Explicit memory • Attention dynamically allocated to salient moments in time • Attentional processes are embodied • Attention and timing are interwoven, involved in sensorimotor coupling Balinese Dance Group 1 Fred Eye-Movement: Lucidity Research • EEG mapping of lucid dreaming • Lucid Dreams generally initiated during periods of high ANS activity • decreased finger pulse amplitude • increased respiration rate and irregularity • increased eye-movement activity relative to normal REM sleep • Lucidity occurs during periods of relatively high brain activation • sufficient CNS activation necessary before consciousness can be attained LaBerge, S., Levitan, L., & Dement, W.

Balinese Dance Group 1 Long-Term: See Fred, see Fred Dance • MNS and Dance – trained dancers showed more activity of MNS to known dances when compared to nondancers - Daniel Glaser • Benefits of Dance – Movement can serve as a mediator to facilitate behavioral change and well being. http://www.pbs.org/wgbh/nova/sciencenow/3204/01-resup.html Javier Balinese Dance Group 1 Mind-Body Connection • Rhythm – “People moving in the same rhythm with the same spatial configuration become identified with one another. Gradually they assume a common expression, moving with the same dynamic qualities (effort synchrony), in comparable areas of space (spatial synchrony), to the same rhythm (rhythmic synchrony. In this way the group achieves a sense of solidarity.” (p.19, Moreno 1988) – Mind/Body Connection Javier Balinese Dance Group 1 Mind-Body connection • Effects of rhythmic sounds on the brain – Beat &Tempo • Pulse rate, galvanic skin response, and blood pressure stabilize to match external tempi. • Respiration and metabolism accelerate. • Rhythmic Movements – An inherited biological response regulated by internal rhythmic generators and reactive to external rhythmic factors Javier Balinese Dance Group 1 Discussion • What are ASCs? – Lack of PFC activity - Attention Shift • Rhythm and collective consciousness • Social cognition and music • Dance Dance Revolution Balinese Dance Group 1 Works Cited • Bandem, I. and deBoer, F.
