In this video, Berklee Online professor Susan Rogers explains musical consonance and dissonance with tonotopicity, the area of psychoacoustics that maps frequency-specific sweet spots in the cochlea. She discusses how simultaneous frequencies can interact with each other, how the interactions are perceived, and how the ratios of these frequencies can be defined and studied.
About Susan Rogers:
Susan Rogers is a professor at Berklee College of Music in the departments of Music Production & Engineering and Liberal Arts, and is the director of the Berklee Music Perception and Cognition Laboratory. Susan holds a Doctorate in Psychology from McGill University; her research focuses on auditory memory, the perception of musical signals, and the influence of musical training on auditory development. For two decades prior to her science career, Susan was one of the world's few women known for her work as a record producer, engineer, mixer, and audio electronics technician. Career highlights include five years (1983-1987) as staff engineer for Prince, producing hit singles for diverse artists such as Barenaked Ladies, David Byrne, Robben Ford, Jeff Black, and Rusted Root, mixing hit singles for an equally eclectic list including Tricky, Michael Penn, Toad the Wet Sprocket, and Tevin Campbell, and engineering for a host more.

This was really great, and I LOVE the physical analogies; however, would've been AWARD WINNING if supplemented with corresponding graphics and, of course, audible examples. Still, so very much appreciated!

[@Thelonious2Monk]

Thanks. The 64,000 dollar question, though, is why we are so keen on hearing "smooth" tone rather than "rough" tone. I have no problem in touching corduroy but hate listening to dissonances. There must be an evolutionary reason for our love for harmonic sounds.

[@ygzok]

I've always heard about psychoacoustics but never bothered to actually learn what it is. This video was incredibly informative. Thanks a lot!

[@shayeasy]

Susan Rogers is absolutely brilliant

[@jacobchateau6191]

I love the way this lecture was composed.

[@69Harveyb1]

omg 😉

[@torley]

I ADORE how you use the metaphors @ 4:34 with your mouth sounds, comparing to silk vs. corduroy makes for a more vivid example. The only thing this video is missing are some actual audio examples themselves!

[@AnalogKitchen]

Wow. I love this! I might do a video on how this would work using analog synthesis

[@kaspartambur]

I enjoy how you yourself can tell, that some information that you are presenting will be hard for the new listener and try your very best to help with hand gestures and speaking tone ! :)

[@dianamccandless7094]

NOW I UNDERSTAND! OMG this is fantastic to know (for sure). I was suspecting these things. I'm a numbers girl, so "very high integer ratios like 32/45...." I knew I had found the right place.

[@VocalChainsStudio]

Awesome! Thank you for sharing this.

[@tonydeltablues]

Good one Professor Rogers - I'm off to get my corduroys on with my silk pocket square ;-) Thanks :-)

[@x1thesoul172]

I had to learn all this the hard way with much experimentation using synthesizers. I love how she presented it! Not sure how easily some people would follow along. But wow that was so lovely.

[@honeypotter1840]

I am ‘some people’ and I’m about to watch this for the second time, again 😂

[@DougGrinbergs]

Interesting, complex math elements of psychoacoustics

[@colintesla]

this is my jam

[@culain6633]

LOOOOVE this video

[@youreright6627]

This is Great, thanks a lot

[@owendoconnor]

Brilliant

[@danielpittman889]

Her voice is somewhere between Lorraine Bracco and Joan Cusack.

[@kalyankrghosh819]

Thank❤❤❤❤

[@luanaudio]

That was great! What subjects does she teach?

[@ethanshephard]

Music cognition

[@donalgreenwood5890]

It’s not that hard to do so

[@AnthonyCarrier]

Psychoacoustics? I though that was me, "A lunatic with an acoustic guitar!"

[@joepalmer5251]

I like tacos

[@tonygohagan2766]

So: just Describe what you've discovered, proper-name the field of pursuit, and as much as possible associated with it, in academic language (Greek/Latin) and hey presto!... now you own a territory which affords you jobs, funding, occupation, status and the semblance of superior insight - but what's really being revealed is the obviousness and inadequacy of your interpretation, hence "Silk, Corduroy, Denim".

god forbid someone use a metaphor to explain science in layman's terms
