i am the author of the "this is your brain on music. " i am a professor of psychology and behavioral neuroscience. i am delighted to introduce you to my friend, one of my famous -- favorite guitarists and musicians. he discovered the guitar at a young age. he has played at notable vilnius such as the -- notable venues such as montrose and carnegie hall. >> i would like to start by saying that in the last 15 or 20 years of my research, one thing i found most surprising as a musician myself in exploring music and the brain is how -- discovering where it is that

music is. i always imagined as a player that the music was in my fingers. now i know is in the brain. it is a neuro-representation of the figures. music is in every part of the brain that we have mapped. there is no part of the brain that does not have something to do with music. i found that very surprising. i wondered if you find that surprising as a player and what your own intuitions were coming into it. >> i think my intuition is that music is something that gets received in some sense or another, like radio, like something you pick up. it is a vibration. when i have written my own music for the guitar, a lot of times it is the result of having experienced something and having to absorb it like you might absorb a vibration or

light our experience something rhythmic like walking down the street. >> a lot of composers say they feel like they are not really creating the music. they're channeling it. roseanne cash talks about holding up her catcher's mitt and catching one as it goes by. someone else talks about how the music is everywhere for anyone to take, that you just have to tune into it. >> driving down here today, there was a rough patch of road because there was construction. you are feeling the road. it makes you aware that no matter where you are or what you are doing, you could be some ki, and you hear something may be rise out of that rhythm. for me, personally, a lot of times the idea for writing a

piece of music or making arrangement comes from some sort of rhythm. a lot of people would say, do you get the melody first or the rhythm? i always say i get the rhythm first and the melody comes out of it. >> could you play us an example of may be something where the rhythm came first? and maybe just play the rhythm. >> i will try. this is a piece called "cumulus rising." this is from a piece that i did in 1998, on the theme of water. this is sort of the theme of water rising through a team less clout. it does not have to be, but that is the sensation that gave me the idea. -- cumulus cloud. >> if you could play the rhythm

first. >> i will tap it. [tapping] pretty simple. then i will play a little bit of it. ♪

>> i will leave it there. [applause] >> one of the things that people often ask is what is happening in our brains when we hear a piece of music. it is extraordinarily complicated. a sound enters the years and there is a cascade of their rick complicated processes that turn the changes in air pressure to an electrical signal which gets transmitted from the year to the brain. once it hits the brain, it gets even more complicated.

it turns out there are distinct regions of the brain that process different aspects of the sound. one part of the brain, you can think of it as a special purpose circuit, attending to and processing their read them. then there is a separate part processing the pitch, a separate part combining the pitches and duration into melodies, a part separate from that attending to how loud or soft it is, and it all comes together later and get this seamless impression of this beautiful melody and harmony, yet, it is processed piecemeal. one of the sources of information of this is we have patients who are damaged in one focal portion of the brain and they lose one of those elements while retaining the others. they may lose rhythm or they will have to pitch and harmony. >> is it processed in real time?

simultaneously? >> yes, but quickly. when i say later, later in brain time means maybe 1/30 of a second later. any second, it can be disrupted , and you to organic brain injury or trauma, it can be disrupted. it is remarkable. the player, at some level, perhaps unconsciously, are having to think about the elements unconsciously. >> i teach a lot of workshops and a lot of people come to play our master classes, they come with their own performance, arrangement. they are looking for feedback. one of the things that i always say, because, as a musician, we try to get everything at once. all of the elements.

we tried to simultaneously get the rhythm, melody, the subtleties, dynamics, accent, all those things that make music interesting. but a lot of times, it is good practice to tear them apart. solo guitar playing, for example, polyphonic music, you have a melody and a baseline, maybe an accompaniment, 3rd voice or harmonic accompaniment. i always suggest people to tear them apart, work on the melody, just work on the base, rhythm, accompaniment. that provides an important process to understanding how these elements have to happen simultaneously. >> when you are writing, as a fan of yours, for decades now -- i think your first record came

out in the 1970's. >> 1978. >> that is right. as a fan, one of the things that struck me is you did not sound like anyone else i had heard, and you still do not. when i listen to any other guitarist,, composer, you can hear their influence, who they took this idea or technique from. your music just sounds fresh and novel. i wonder if you might be willing to disclose to us some of your influences and how they gave rise to your compositional playing style, and maybe demonstrate them. >> i like to joke, i did not learn how to play anything else really well, so i had to come up with my own. it is true, i found this out

later when i was teaching. can you show me that solo to that song? do you know how it goes? i am useless at that. i am not very good at cataloging other people's music. i certainly had my influence is growing up. i started playing the guitar when i was 12th. i was a big fan of the pope, blue, british isles scene, mississippi john hurt me, sonny terry brown mcgee, i played some blues harmonica. >> did you learn that open tuning style, slide style? >> i have not picked up a slide in a long time, so i do not want to embarrass myself, but yes. it was a lot of folk music, blues and early on.

i fell in love with the sound of the steel string guitar. there are a lot of idiomatic thing that it does well. i studied classic guitar a bit, but the steel string, for example, we do something called a hammer on and pull off, which is -- >> you get three note for the price of one. >> you plug the string but you get four notes. i always think of that town at the the prototypical steel string guitar sound. british isles, a caltech music. i learned all the paul simon songs. as i got older -- >> he is a hell of a guitarist. people do not realize. he is not flashy, but if you try to learn his tunes, they are

really hard. >> he is a brilliant guitar player. i eventually got interested in jazz, world music, everything. maybe that is one of the reasons. i enjoyed so many kinds of music, i did not have a preference. i did not want to be anything in particular. i just wanted to play guitar and get that sound that i was hearing in my head. >> is there a particular song of yours that you can trace back to and influence, sound that you were trying to get that you heard somebody else use and you wanted to use it? >> i will play you a few bars from a piece that i wrote in the 1970's, very much influenced by the british isles style. this one is called "inverness."

♪ >> i am cutting it short, but, to me, that is the quintessential british isles style. >> although, in your hand, it is more harmonically complex. >> it could be. >> one of the things i was trying to do -- i became a big fan of keith jarrett when i was young. i thought, wow, if i can do something like that with a guitar -- and i remember, i was a student at uc-berkeley, considering going to graduate school in economic geography and working as an intern coming here

at the san francisco planning department. i was also a record in my first album. i wrote this piece called " turning, turning back." it began the recording but it also began a new direction for me. they say every musician that starts recording for writing, arranging music, they have to find their own voice. i think i may be found my own voice in that one. >> are you going to play some of it? ♪ >> just playing an excerpt from

the middle, -- time part. -- double-time part. the main theme -- ♪ [applause] >> that is the main theme. >> often, when i listen to guitar players, because i'm a guitarist myself, i'm trying to figure out what they are doing and how they do it. i cannot do that when i listen to you. the music for " washes over me. for me, it isso
