1
00:00:01,573 --> 00:00:04,207
The philosopher Plato once said,

2
00:00:04,231 --> 00:00:06,980
"Music gives a soul to the universe,

3
00:00:07,004 --> 00:00:08,598
wings to the mind,

4
00:00:08,622 --> 00:00:10,644
flight to the imagination

5
00:00:10,668 --> 00:00:12,626
and life to everything."

6
00:00:13,793 --> 00:00:16,081
Music has always been
a big part of my life.

7
00:00:16,105 --> 00:00:18,475
To create and to perform music

8
00:00:18,499 --> 00:00:21,344
connects you to people
countries and lifetimes away.

9
00:00:21,777 --> 00:00:24,130
It connects you to the people
you're playing with,

10
00:00:24,154 --> 00:00:25,342
to your audience

11
00:00:25,366 --> 00:00:26,693
and to yourself.

12
00:00:27,132 --> 00:00:29,283
When I'm happy, when I'm sad,

13
00:00:29,307 --> 00:00:31,507
when I'm bored, when I'm stressed,

14
00:00:31,531 --> 00:00:34,101
I listen to and I create music.

15
00:00:35,716 --> 00:00:37,987
When I was younger, I played piano;

16
00:00:38,011 --> 00:00:39,408
later, I took up guitar.

17
00:00:39,432 --> 00:00:41,265
And as I started high school,

18
00:00:41,289 --> 00:00:43,203
music became a part of my identity.

19
00:00:43,509 --> 00:00:44,926
I was in every band,

20
00:00:44,950 --> 00:00:47,576
I was involved with every
musical fine arts event.

21
00:00:48,158 --> 00:00:49,565
Music surrounded me.

22
00:00:49,589 --> 00:00:50,944
It made me who I was,

23
00:00:50,968 --> 00:00:53,078
and it gave me a place to belong.

24
00:00:54,656 --> 00:00:56,753
Now, I've always had
this thing with rhythms.

25
00:00:56,777 --> 00:00:57,946
I remember being young,

26
00:00:57,970 --> 00:01:00,034
I would walk down
the hallways of my school

27
00:01:00,058 --> 00:01:03,048
and I would tap rhythms to myself
on my leg with my hands,

28
00:01:03,072 --> 00:01:04,792
or tapping my teeth.

29
00:01:05,684 --> 00:01:07,163
It was a nervous habit,

30
00:01:07,187 --> 00:01:08,470
and I was always nervous.

31
00:01:08,840 --> 00:01:11,126
I think I liked the repetition
of the rhythm --

32
00:01:11,150 --> 00:01:12,510
it was calming.

33
00:01:13,957 --> 00:01:15,107
Then in high school,

34
00:01:15,131 --> 00:01:16,644
I started music theory,

35
00:01:16,668 --> 00:01:18,898
and it was the best class I've ever taken.

36
00:01:18,922 --> 00:01:20,456
We were learning about music --

37
00:01:20,480 --> 00:01:23,169
things I didn't know,
like theory and history.

38
00:01:23,836 --> 00:01:27,236
It was a class where we basically
just listened to a song,

39
00:01:27,260 --> 00:01:28,888
talked about what it meant to us

40
00:01:28,912 --> 00:01:30,098
and analyzed it,

41
00:01:30,122 --> 00:01:32,588
and figured out what made it tick.

42
00:01:33,710 --> 00:01:36,770
Every Wednesday, we did something
called "rhythmic dictation,"

43
00:01:36,794 --> 00:01:38,196
and I was pretty good at it.

44
00:01:38,772 --> 00:01:41,027
Our teacher would give us
an amount of measures

45
00:01:41,051 --> 00:01:42,544
and a time signature,

46
00:01:42,568 --> 00:01:44,432
and then he would speak a rhythm to us

47
00:01:44,456 --> 00:01:47,872
and we would have to write it down
with the proper rests and notes.

48
00:01:48,412 --> 00:01:49,683
Like this:

49
00:01:50,622 --> 00:01:53,099
ta ta tuck-a tuck-a ta,

50
00:01:53,123 --> 00:01:55,676
ta tuck-a-tuck-a-tuck-a, tuck-a.

51
00:01:56,832 --> 00:01:58,137
And I loved it.

52
00:01:58,161 --> 00:01:59,639
The simplicity of the rhythm --

53
00:01:59,663 --> 00:02:01,821
a basic two- to four- measure line --

54
00:02:01,845 --> 00:02:04,649
and yet each of them almost told a story,

55
00:02:05,597 --> 00:02:07,904
like they had so much potential,

56
00:02:09,250 --> 00:02:12,444
and all you had to do was add a melody.

57
00:02:13,580 --> 00:02:17,482
(Guitar)

58
00:02:21,588 --> 00:02:25,587
Rhythms set a foundation for melodies
and harmonies to play on top of.

59
00:02:25,988 --> 00:02:28,165
It gives structure and stability.

60
00:02:29,520 --> 00:02:31,200
Now, music has these parts --

61
00:02:31,224 --> 00:02:33,359
rhythm, melody and harmony --

62
00:02:33,383 --> 00:02:34,864
just like our lives.

63
00:02:35,552 --> 00:02:37,588
Where music has rhythm,

64
00:02:37,612 --> 00:02:39,866
we have routines and habits --

65
00:02:39,890 --> 00:02:43,155
things that help us to remember
what to do and to stay on track,

66
00:02:43,179 --> 00:02:45,058
and to just keep going.

67
00:02:46,230 --> 00:02:48,055
And you may not notice it,

68
00:02:48,079 --> 00:02:49,402
but it's always there.

69
00:02:50,666 --> 00:02:53,035
(Guitar)

70
00:02:53,059 --> 00:02:54,876
And it may seem simple,

71
00:02:54,900 --> 00:02:57,597
it may seem dull by itself,

72
00:02:58,587 --> 00:03:01,901
but it gives tempo and heartbeat.

73
00:03:03,623 --> 00:03:06,056
And then things in your life add on to it,

74
00:03:06,080 --> 00:03:07,291
giving texture --

75
00:03:07,906 --> 00:03:09,659
that's your friends and your family,

76
00:03:09,683 --> 00:03:13,319
and anything that creates
a harmonic structure in your life

77
00:03:13,343 --> 00:03:14,928
and in your song,

78
00:03:14,952 --> 00:03:16,614
like harmonies,

79
00:03:16,638 --> 00:03:17,795
cadences

80
00:03:17,819 --> 00:03:20,115
and anything that makes it polyphonic.

81
00:03:22,378 --> 00:03:24,765
And they create beautiful
chords and patterns.

82
00:03:24,789 --> 00:03:26,374
(Guitar)

83
00:03:27,354 --> 00:03:28,943
And then there's you.

84
00:03:29,401 --> 00:03:31,351
You play on top of everything else,

85
00:03:33,321 --> 00:03:36,335
on top of the rhythms and the beat

86
00:03:37,859 --> 00:03:39,488
because you're the melody.

87
00:03:41,154 --> 00:03:44,335
And things may change and develop,

88
00:03:45,226 --> 00:03:46,786
but no matter what we do,

89
00:03:46,810 --> 00:03:48,428
we're still the same people.

90
00:03:50,110 --> 00:03:52,291
Throughout a song melodies develop,

91
00:03:52,315 --> 00:03:54,015
but it's still the same song.

92
00:03:55,253 --> 00:03:57,037
No matter what you do,

93
00:03:57,061 --> 00:03:58,987
the rhythms are still there:

94
00:03:59,011 --> 00:04:02,137
the tempo and the heartbeat ...

95
00:04:04,209 --> 00:04:05,660
until I left,

96
00:04:07,155 --> 00:04:08,744
and I went to college

97
00:04:08,768 --> 00:04:10,241
and everything disappeared.

98
00:04:12,611 --> 00:04:14,810
When I first arrived at university,

99
00:04:14,834 --> 00:04:16,059
I felt lost.

100
00:04:16,714 --> 00:04:19,744
And don't get me wrong --
sometimes I loved it and it was great,

101
00:04:19,768 --> 00:04:21,148
but other times,

102
00:04:22,961 --> 00:04:24,633
I felt like I had been left alone

103
00:04:25,970 --> 00:04:27,387
to fend for myself.

104
00:04:28,603 --> 00:04:31,417
It's like I had been taken out
of my natural environment,

105
00:04:31,441 --> 00:04:32,786
and put somewhere new,

106
00:04:32,810 --> 00:04:35,642
where the rhythms and the harmonies

107
00:04:35,666 --> 00:04:38,323
and the form had gone away,

108
00:04:39,638 --> 00:04:41,007
and it was just me --

109
00:04:41,031 --> 00:04:42,356
(Guitar)

110
00:04:42,380 --> 00:04:44,653
silence and my melody.

111
00:04:47,930 --> 00:04:50,425
And even that began to waver,

112
00:04:50,449 --> 00:04:52,401
because I didn't know what I was doing.

113
00:04:53,074 --> 00:04:55,470
I didn't have any chords
to structure myself,

114
00:04:56,389 --> 00:04:57,547
or a rhythm

115
00:04:58,240 --> 00:04:59,967
or a beat to know the tempo.

116
00:04:59,991 --> 00:05:03,461
(Guitar)

117
00:05:03,485 --> 00:05:05,797
And then I began to hear
all these other sounds.

118
00:05:05,821 --> 00:05:07,167
(Guitar)

119
00:05:07,670 --> 00:05:09,479
And they were off-time

120
00:05:10,779 --> 00:05:12,134
and off-key.

121
00:05:14,944 --> 00:05:16,512
And the more I was around them,

122
00:05:17,716 --> 00:05:20,869
the more my melody started
to sound like theirs.

123
00:05:24,260 --> 00:05:26,427
And slowly I began to lose myself,

124
00:05:28,515 --> 00:05:29,957
like I was being washed away.

125
00:05:33,184 --> 00:05:34,681
But then the next moment --

126
00:05:34,705 --> 00:05:36,691
(Guitar)

127
00:05:36,715 --> 00:05:38,208
I could hear it.

128
00:05:39,634 --> 00:05:41,055
And I could feel it.

129
00:05:43,250 --> 00:05:44,502
And it was me.

130
00:05:45,464 --> 00:05:46,690
And I was here.

131
00:05:47,735 --> 00:05:49,269
And it was different,

132
00:05:50,819 --> 00:05:52,234
but not worse off.

133
00:05:54,408 --> 00:05:56,695
Just changed a little.

134
00:05:59,526 --> 00:06:02,811
Music is my way of coping
with the changes in my life.

135
00:06:04,438 --> 00:06:07,087
There's a beautiful connection
between music and life.

136
00:06:07,487 --> 00:06:08,793
It can bind us to reality

137
00:06:08,817 --> 00:06:11,209
at the same time
it allows us to escape it.

138
00:06:11,233 --> 00:06:13,753
Music is something
that lives inside of you.

139
00:06:13,777 --> 00:06:16,427
You create it and you're created by it.

140
00:06:17,727 --> 00:06:20,839
Our lives are not only conducted by music,

141
00:06:20,863 --> 00:06:22,494
they're also composed of it.

142
00:06:23,528 --> 00:06:25,640
So this may seem like a bit of a stretch,

143
00:06:25,664 --> 00:06:27,231
but hear me out:

144
00:06:27,255 --> 00:06:30,845
music is a fundamental part of what we are

145
00:06:30,869 --> 00:06:32,342
and of everything around us.

146
00:06:33,276 --> 00:06:34,696
Now, music is my passion,

147
00:06:34,720 --> 00:06:37,147
but physics also used to be
an interest of mine.

148
00:06:37,649 --> 00:06:38,806
And the more I learned,

149
00:06:38,830 --> 00:06:41,059
the more I saw connections
between the two --

150
00:06:41,678 --> 00:06:43,549
especially regarding string theory.

151
00:06:45,275 --> 00:06:48,013
I know this is only one of many theories,

152
00:06:48,037 --> 00:06:49,543
but it spoke to me.

153
00:06:50,391 --> 00:06:55,287
So, one aspect of string theory,
at its simplest form, is this:

154
00:06:55,311 --> 00:06:57,337
matter is made up of atoms,

155
00:06:57,361 --> 00:07:00,579
which are made up of protons
and neutrons and electrons,

156
00:07:00,603 --> 00:07:02,329
which are made up of quark.

157
00:07:02,353 --> 00:07:04,386
And here's where the string part comes in.

158
00:07:04,410 --> 00:07:07,941
This quark is supposedly made up
of little coiled strings,

159
00:07:08,696 --> 00:07:12,884
and it's the vibrations of these strings
that make everything what it is.

160
00:07:13,751 --> 00:07:15,302
Michio Kaku once explained this

161
00:07:15,326 --> 00:07:18,258
in a lecture called,
"The Universe in a Nutshell,"

162
00:07:18,282 --> 00:07:19,657
where he says,

163
00:07:20,504 --> 00:07:22,744
"String theory is the simple idea

164
00:07:22,768 --> 00:07:24,796
that the four forces of the universe --

165
00:07:24,820 --> 00:07:29,006
gravity, the electromagnetic force,
and the two strong forces --

166
00:07:29,030 --> 00:07:31,005
can be viewed as music.

167
00:07:31,029 --> 00:07:33,724
The music of tiny little rubber bands."

168
00:07:34,624 --> 00:07:36,939
In this lecture, he goes on
to explain physics

169
00:07:36,963 --> 00:07:39,372
as the laws of harmony
between these strings;

170
00:07:39,396 --> 00:07:42,433
chemistry, as the melodies
you can play on these strings;

171
00:07:43,145 --> 00:07:47,258
and he states that the universe
is a "symphony of strings."

172
00:07:49,439 --> 00:07:51,507
These strings dictate the universe;

173
00:07:51,531 --> 00:07:54,064
they make up everything we see
and everything we know.

174
00:07:55,088 --> 00:07:56,298
They're musical notes,

175
00:07:56,322 --> 00:07:59,059
but they make us what we are
and they hold us together.

176
00:08:00,357 --> 00:08:01,629
So you see,

177
00:08:02,267 --> 00:08:03,828
everything is music.

178
00:08:04,471 --> 00:08:05,835
(Guitar)

179
00:08:05,859 --> 00:08:07,989
When I look at the world,

180
00:08:08,013 --> 00:08:11,344
I see music all around us.

181
00:08:13,264 --> 00:08:14,803
When I look at myself,

182
00:08:15,814 --> 00:08:17,280
I see music.

183
00:08:21,348 --> 00:08:23,524
And my life has been defined by music.

184
00:08:25,468 --> 00:08:27,102
I found myself through music.

185
00:08:29,361 --> 00:08:30,824
Music is everywhere,

186
00:08:31,837 --> 00:08:33,422
and it is in everything.

187
00:08:36,411 --> 00:08:39,197
And it changes and it builds

188
00:08:39,221 --> 00:08:40,697
and it diminishes.

189
00:08:42,570 --> 00:08:43,991
But it's always there,

190
00:08:44,771 --> 00:08:46,405
supporting us,

191
00:08:46,429 --> 00:08:48,127
connecting us to each other

192
00:08:49,171 --> 00:08:51,383
and showing us the beauty of the universe.

193
00:08:53,048 --> 00:08:54,646
So if you ever feel lost,

194
00:08:55,391 --> 00:08:57,539
stop and listen for your song.

195
00:08:58,541 --> 00:08:59,823
Thank you.

196
00:09:00,678 --> 00:09:03,702
