right. it's up to you how much of the south africa going to get. itself can. physically. change our behavior in a radical way it can create moods that creates a physical reaction in the body in the street noise laws just this is just already a language which can communicate so much we never speech of actually hearing because everything what is moving everything what is living as a frequency that's a risk even if deep before we are born we have to the experience of self.

one of the interesting things that i picked up on was how different the arches were i mean between them all because they all seem very similar in makeup and shape and size it depends whether focusing point as compared to the ground is above the ground and it's not really a cliff but the head you don't hit face right on the ground you get this reinforcement sign goes down and up and down and up and there's all kind of weird accused effects which you know we've all been listening to for millennia i mean this is this coast theories to. is placed in places where the echoes are particularly interesting so you can paint a picture of a figure and you stand but by go out in the sun will come off and it will look like the person's to a hit sound of a person's. it's rather strange as an archaeologist to have an interest in music. because the past

is of course totally sonnet to us. we know that some of the most elaborate painted panels in the caves or soon in the case will go in most domestic acoustics. so we sped those paintings were associated with singing dancing musicality. this is a typical train or tram noise and i wonder what your sponsors to. i won't be long enough i think i'm so yeah it's really been pleasant on the ear how how calm and of a theory has it is that there scraping sounds on pleasant because they sound a bit like a scream and in our brains we have a very short will sponsor mechanism to deal with danger that's what hearing was 1st

of evolution it was an early warning system so you'll find a lot of cities doing things like bringing fountains into squares because it gives you the sound of nature and you can do things that high traffic noise with it and of course we like the sound of nature is good for us you know in evolution returns we're used to living not in a city but out in the countryside and when there's water there's there's going to be food this going to be what's for us to drink so we naturally find a pleasant sound. and was quite curious about sound is actually sound waves a really weak or a physical point a few tiny little motions of their motor kills but to us you know we have these big big emotional feelings responding to this week little force. thank you. for.

30. to. the.

when i'm really ancestors going back to maybe 3000000 years communicated with musicality they did that to express emotions to manipulate emotions to build social relationships because that was before language so we asked what was all this ability to be receptive to sounds what was all being used to have music it was it was being used for making music or of making conversation is limited. humans are social creatures it was our hearing that enabled us to build communities

and to secure the survival of our species through evolution. the importance of our audio functions can be discerned from the moment we are born. babies are like superman when babies are born they are musical so they can discriminate between the rhythm of their native language and rhythms of other languages but more interesting will and at age of 4 days after birth babies are already crying in the stress pattern of their mother tongue it's the genes had an influence on the brain structure that made us at one point musical and also able to process language.

so. i started playing piano when i was 3 i would just annually sounds that i would hear in the room. and just learning by ear. overgrown place apocalyptic house take 2.

children are perfect musicians and really they have to superior appearing and superior pitch and then somewhere along the way if those skills are perfected if they're not worked on then you lose it but and it's infancy i feel like we're designed to be these perfectly pitched musical instrument. and there's a huge space for innovation within the integration of music and technology that is going to come entirely from the younger generations. and really interested in helping young girls young women get into. said in the technological aspects of music making.

computers is actually de monetizing the music industry you could actually create an entirely new form of music and your own right and way of listening and writing music and the traditional approach to learning music is not necessary for that process and i'm excited to see where it's going to go because it's limitless.

we're using different methods to see where and when the brain processes music so that those methods like functional magnetic resonance imaging where we put people into the scanner and see which brain areas consume more oxygen means they are active during listening to music playing music also we use methods like transfer philosophy where we have little sensors electrodes on the scalp to record brain potentials with a millisecond resolution to really tell when things are happening and we have methods where we stimulate the brain to make one brain area more or less efficient to see which effects this has on music perception and production.

i started to play the piano i be a ship 3 and my family couldn't imagine that i could be a professional pianist of professional musician. nobody of my family are musician i realize that music is so great means for me to have a conversation with the people and to get into the social like most shouted to things in the wall with musicians who use both hands while playing this is done by the 2 hemispheres that need to communicate more strongly than in the non-musician the auditory areas are refined musicians are better able to discriminate between 2 pitches. we're fascinated by how musicians perform on stage with great speed and accuracy and how they are doing this.

pianist when planning on the movements is always like 5 or 6 tones ahead in his or her mind. we were interested in whether we can influence this planning process maybe boost this planning process by brain stimulation. and i sat here. do you think you see. such as a will to an experimental music production. and why you're doing this we've asked him with a one area in your brain asked located about here and to find this area i'll do

some near an education with you and what will happen us there so you are see hands of a pianist on the screen playing the piano playing what sequences and your task will be to do exactly the same on the piano on your own piano just the need to actually see on the screen all right ringback.

and what we hope to find is that the stimulation indeed boasts performance boosts the planning process ace. so one could take this as adopting for the pianist but personally i admit i would prefer natural pianists because they are already performing accidentally on stage. i feel like we're very very close with this whole reverse engineering gram research and if you can create this blueprint of all the neural connections in your brain and build a supercomputer that would map all of these functions out you can send very noninvasive along. you're cool stimulus to your brain and be able to manipulate the emotional state the mental state so essentially that's going to change the way that we listen to music because we won't necessarily need speakers to you hear and

experience music. one of the power of music for example is that it can have an influence on you and you don't know why. the history of music is not only f.p.s. or. have green wall songs to manipulate and music has been used for torture and that's a terrible history. in england it's been an interesting development marks and spencers a big public stories decided to turn off music entirely and there was silence which is an interesting choice because most shops are using music to manipulate behavior and so on this will surely home. how is it that some external combination of

musical sounds has like an emotional impact on human beings perhaps there are certain frequencies that are more harmonious with the way that our physical chemistry is taking my music and switching it from 440 hertz to 432 and like listening to the differences so on my record i definitely did that to certain tracks and some of the sounded and it just felt more warm and like more or more bracelet.

2 experienced with the mafia a group of people who had never before listened to western type of music they hear musical piece and the meters really realize this is sad something that seems to be partly universal in this rituals experience a creative muse.
