Consciousness
The astounding influence of
music on cognition

Ties to ASCs
Shift state, alter mindset
Used to accompany, induce ASCs:
Religion/shamanism/mysticism
Drug use
Meditation
Sleep
What is Music?
Distinguishing aspects
Tonal organization; psychoacoustics
Beat & rhythm
Affect
Birdsong?
Jackhammer?
Country?
Basic Structure
Hierarchy
Major and minor beats
Essential + ornamental notes
Defeasible principles of organization
Interaction between types and levels
Auditory “scene” analysis: stream
segregation
Processing music
Utilizes broad cognitive capacities
Gestalt grouping: proximity, good
continuation
And specialized ones
Differential lateralization in
processing
Analysis of tonal space: pitches,
intervals, chords, keys
Affect in music
Music theory
There are “degrees of tension and
attraction within a melody…at any point”
Rising pitch: increased tension
Large interval shifts: more tension than
small shifts
Attraction related to “resolution” during
melodic progression
Conscious and unconscious expectation;
latter unrelated to memory

Why does music move us?
Aesthetics: Admiring beauty,
virtuosity
Memory: Nostalgic familiarity
Entrainment: direct effect on
rhythms within the body (heartbeat,
brainwaves); visceral and motor
rhythmicity
Why does music move us?
“Musical posture” and “gesture”:
ascription of affect and animatism
Listening to “dark” music doesn’t make us
feel dark, but in the presence of a dark
entity
We have empathy or attunement with the
affect
Dancing: conversion to physical posture
and gesture
Framing: level to invest, or detach
The Impact of Music on the
Brain & Experience
Neural Basis for Coupling Music
to Emotion & Attention
PET studies showed increased CBF in the ventral
striatum, midbrain, amygdala, orbitofrontal cortex,
and ventral medial prefrontal cortex (Limb, 2006)
EEG studies have shown a significant power increase
in the low-alpha band range in bilateral frontal
networks, indicating increased neuronal
synchronization and attention (Thaut, 2005).
Music acts on waking arousal control systems based
on norepinephrine (NE) and serotonin (Panksepp,
1986).
Music elicits responses similar
to sex and drug intake
Music can lead to musical chills and euphoric experience
Music activates reward related brain areas
These area’s are similar to reward / emotion and limbic
arousal processes similar to thoses activated by drug intake
and sex.
NAc, Insula, OFC, ACC (Blood, 2001)
Increased DA secretion due to listening to music.
Music is your XTC! Remember Volkow? Is music addictive?
?
Music and Brain
Lateralization
Right hemisphere is involved in processing of
melody (prosody)
Left hemisphere is involved in processing rhythm
and musical analysis. Also activates frontal motor
areas
Is the left hemisphere involved in making you want
to shake your body?
Is music capable of inducing
an altered state?
Is used for induction of hypnosis/
trancelike states
Music can drive listeners into states
of patriotic fervor or religious frenzy
Is there a reason why we sing in
church?
Does music induce religious
experiences?
What is music therapy?
Systematic intervention process that uses music
experiences to achieve therapeutic goals
Music as an ASC: changes in emotion, motivation,
motor functions to help a variety of patient
populations
Passive and active interactions with music:
Song writing, listening to music, discussion of song
lyrics, performing, etc.
No previous experience with music or music talent is
necessary
Music Therapy patient
populations
Goals:
Obtain symptom control, reduce clinical disability,
improve quality of life
Vary with each patient’s condition:
Geriatric care
Patient’s undergoing cardiac surgery
Parkinson’s disease
Rehabilitation
Alzheimer's- “silent brain”
Schizophrenia, bipolar disorder, Tourette’s
Active music therapy
Voice exercises, rhythmic and free
body movements
Combining motor and emotional
responses
Rhythmic and melodic components
Combining stimulation of different
sensory pathways
Active MT and Parkinson’s
Disease
Bradykinesia,hypokinesia
Postural and gait abnormalities
External rhythmic cues acting as a timekeeper
Variable improvements
Motor improvements as a function of emotion?
DA mesolimbic projections to ventro-striatum
intraccumbens
Integration of basal-ganglia loop and cortical regions
Limbic systems + motor systems
Music therapy and effects on consciousness
Improvements seem to be residual
ASC’s generally relative
Individual differences in normal state of
consciousness
(Pacchetti et al.)
Patients achieve different mental state and physical
state
Body and mind connection (Brain vs. Mind)
Is music adaptive? What
purpose might music
serve on an individual
and social level?
Where Did Music Come
From?
Auditory Cheesecake hypothesis
Steven Pinker, How the Mind Works (1997)
Sexual Selection hypothesis
Geoffrey Miller, “Evolution of human music through
sexual selection” (2000)
Social Bonding hypothesis
Robin Dunbar, “Language, Music and Laughter in
Evolutionary Perspective” (2004)
Coalition Signaling hypothesis
Hagen & Bryant, “Music and dance as a coalition
signaling system” (2003)
Auditory Cheesecake
Cheesecake tastes good by taking
advantage of existing structures
The desire for cheesecake is an
emergent phenomena of existing
processes
Music, too!
Sexual Selection
Darwin: Music as courtship display
Miller: Musical ability as indicator
of fitness
Jimi Hendrix
Social Bonding
Sexual selection is insufficient
Monkey grooming
Grooming ceiling: 50 monkeys
Human grooming
Dunbar’s number: 150 humans
Language allows larger grooming size
Ramping up from 50 to 150
Music, precursor to language
Coalition Signaling
Sexual selection, social bonding
insufficient, but important
Music commonly performed in groups
during war, politics with other groups
Apes coordinate songs to advertise
territory, pair bonds
May also signal group identity
Music signals other groups of cohesion
“We can kick your butt.”
Altered State Induction
What about altered states?
Mob behavior as altered state:
Personal identity frame drop induces
altered state
Are musical groups mobs?
Is music’s role in the induction of altered
states evolutionarily adaptive?
Open question
