Transcript of Researching Music Therapy through Technology

New Approaches to Researching Music Therapy through Music Technology
Dr. Benjamin Smith
Assistant Professor, Department of Music and Arts Technology

Music Technology
any technology used in the production of music
dedicated
Music Technology
any electronic technology used in the production, dissemination, or examination of music
Take 2
Specifically...
Software to examine music
Music Information Retrieval
Music Information Retrieval
Predicated on music as an information medium
Example
Uses software, math, algorithms to "understand" music
What do these pieces contain (information)?
MIR
Primarily concerned with comparison
How much is this (song, melody) like another one?
and retrieval
From huge databases (iTunes, Spotify, Pandora, etc.)
Machine Learning
How MIR works.
Many, many algorithms to train computers to identify patterns.
Examples
Voice recognition
Facial recognition
All MIR applications
Interactive Example
Spectral Mapper

"The effect of improvisational music therapy on the treatment of depression: protocol for a randomised controlled trial" by J. Erkkilä, et. al.
Proposed to use MIR to analyze audio in clinical settings. Wanted to link this analysis to depression treatment.
Can we discover what is _in_ the music used in therapy?
Can we prove it?
Premise
If music is inherently information rich...
and we can reasonably measure/extract/observe/characterize this information...
and we can correlate with therapeutic outcomes and progress...
Q:
We could discover how
specific musical elements
in specific contexts!
have specific impacts
NSF/NIH Proposal
to use recordings from Nordoff-Robbins archive at NYU, correlating MIR-based computational analysis with therapeutic outcomes
def:
many based on neural models
Musical
Information
Pitch content
Range
Intervalic content
Key
Harmony
Rhythmic patterns
Spectral Content (timbre)
