0:00:01.507,0:00:05.354 For many of us right now,[br]our lives are quieter than normal. 0:00:05.984,0:00:08.428 And quiet can be unnerving. 0:00:08.849,0:00:10.374 It can make you feel lonely, 0:00:10.398,0:00:13.911 or just all too aware[br]of the things you're missing out on. 0:00:14.427,0:00:16.627 I think about sound all the time. 0:00:16.934,0:00:18.117 I'm a sound designer, 0:00:18.141,0:00:20.426 and I host the podcast[br]"Twenty Thousand Hertz." 0:00:21.109,0:00:24.803 It's all about the world's most[br]recognizable and interesting sounds. 0:00:25.196,0:00:28.608 But I think this is the perfect time[br]to talk about silence. 0:00:29.085,0:00:30.800 Because what I've come to understand 0:00:30.824,0:00:34.666 is that there is no such thing as silence. 0:00:35.260,0:00:38.236 And the person who opened[br]my mind to this idea 0:00:38.260,0:00:41.335 is one of the most influential[br]composers in history. 0:00:41.359,0:00:43.296 (Piano music) 0:00:43.320,0:00:46.915 John Cage has made an impact[br]on artists in many genres, 0:00:46.939,0:00:50.740 from avant-garde musicians,[br]to modern dance, to pop music. 0:00:51.109,0:00:53.426 Right now, we're listening[br]to his 1948 piece 0:00:53.450,0:00:54.831 called "In a Landscape." 0:00:54.855,0:00:58.387 This version was recorded in 1994[br]by Stephen Drury. 0:00:58.411,0:01:04.768 (Piano music) 0:01:04.792,0:01:08.643 This piece is actually not very typical[br]of John Cage's writing. 0:01:08.667,0:01:12.182 He's more known for his innovations[br]and avant-garde techniques. 0:01:12.206,0:01:14.206 But despite his reputation, 0:01:14.230,0:01:18.752 no one was prepared[br]for what he did in 1952, 0:01:18.776,0:01:22.309 when he created the most daring[br]piece of his career. 0:01:22.657,0:01:26.147 It was called "4'33''," 0:01:26.171,0:01:31.299 and it was a piece that some critics[br]even refused to call "music," 0:01:31.323,0:01:33.887 because for the entire[br]duration of the piece, 0:01:33.911,0:01:35.100 the performer plays 0:01:36.133,0:01:37.434 nothing at all. 0:01:38.243,0:01:41.807 Well, to be technical,[br]the performer is actually playing rest. 0:01:41.831,0:01:44.942 But to the audience,[br]it looks like nothing is happening. 0:01:45.601,0:01:48.299 John Cage's "4'33''"[br]was performed for the first time 0:01:48.323,0:01:50.227 in the summer of 1952, 0:01:50.251,0:01:52.363 by renowned pianist David Tudor. 0:01:52.673,0:01:55.582 It was at the Maverick Concert hall[br]in Woodstock, New York. 0:01:55.606,0:01:59.656 This is a beautiful wooden building[br]with huge openings to the outdoors. 0:01:59.680,0:02:01.903 So, David Tudor walked out on stage, 0:02:01.927,0:02:03.491 sat down at the piano, 0:02:03.515,0:02:05.443 then closed the piano lid. 0:02:05.870,0:02:07.274 He then sat in silence, 0:02:07.298,0:02:09.814 only moving to open[br]and close the piano lid 0:02:09.838,0:02:12.433 between each of the three movements. 0:02:12.457,0:02:13.790 After the time was up, 0:02:13.814,0:02:14.981 he got up 0:02:15.005,0:02:16.671 and walked off the stage. 0:02:17.537,0:02:18.981 (Piano music) 0:02:19.005,0:02:21.598 The audience had no idea what to think. 0:02:22.037,0:02:26.101 It made people wonder if Cage[br]is even taking his career seriously. 0:02:26.125,0:02:27.855 A close friend even wrote to him, 0:02:27.879,0:02:31.260 begging that he not turn[br]his career into a joke. 0:02:31.284,0:02:33.601 John Cage had, well, if you could call it, 0:02:33.625,0:02:35.293 composed a piece of music 0:02:35.317,0:02:38.761 that really challenged[br]some very established ideas 0:02:38.785,0:02:40.313 about music composition. 0:02:40.337,0:02:43.105 It's something that musicians[br]still debate today. 0:02:44.255,0:02:46.786 To understand just what[br]John Cage was thinking, 0:02:46.810,0:02:48.588 let's back up to the 1940s. 0:02:48.612,0:02:49.769 Back then, 0:02:49.793,0:02:53.841 John Cage was making a name for himself[br]composing for the prepared piano. 0:02:53.865,0:02:55.077 (Piano music) 0:02:55.101,0:02:56.315 To make music like this, 0:02:56.339,0:02:59.125 John Cage would put objects[br]inside the piano, 0:02:59.149,0:03:00.482 between the strings. 0:03:00.784,0:03:02.450 Things you just find lying around, 0:03:02.474,0:03:05.505 like screws, tape and rubber erasers. 0:03:05.831,0:03:08.077 So now, you've transformed the piano 0:03:08.101,0:03:10.934 from a tonal instrument[br]with high and low pitches 0:03:10.958,0:03:13.497 into a collection of unique sounds. 0:03:13.800,0:03:16.561 The music you're hearing [br]is Cage's "Sonata V," 0:03:16.585,0:03:18.997 from "Sonatas and Interludes[br]for Prepared Piano." 0:03:19.370,0:03:22.161 Probably his most famous work[br]outside of "4'33''." 0:03:22.703,0:03:25.029 This version was performed[br]by Boris Berman. 0:03:25.997,0:03:28.752 John Cage wrote incredibly[br]detailed instructions 0:03:28.776,0:03:31.593 about where to place[br]each object in the piano. 0:03:31.617,0:03:35.864 But it's impossible for every performer[br]to get the exact same objects, 0:03:35.888,0:03:38.387 so the sound you get is always different. 0:03:38.411,0:03:41.148 Basically, it comes down to random chance. 0:03:41.458,0:03:43.918 This was pretty bananas and pretty alien 0:03:43.942,0:03:47.767 to the way most composers and musicians[br]are taught to do things. 0:03:48.927,0:03:51.458 John Cage was becoming[br]increasingly interested 0:03:51.482,0:03:53.664 in chance and randomness 0:03:53.688,0:03:56.498 and letting the universe[br]provide the answer to the question 0:03:56.522,0:03:58.588 "What note should I play next?" 0:03:59.212,0:04:01.418 But to hear the answer to the question, 0:04:01.442,0:04:03.243 first, you have to listen. 0:04:03.561,0:04:05.014 And in the 1940s, 0:04:05.038,0:04:08.037 listening to the universe[br]was getting harder to do. 0:04:08.458,0:04:10.283 (Elevator music) 0:04:10.307,0:04:12.641 The Muzak company was founded in the '30s. 0:04:12.665,0:04:13.855 It really took off, 0:04:13.879,0:04:17.363 and soon, there was constant[br]background music nearly everywhere. 0:04:17.911,0:04:19.932 It was almost impossible to escape. 0:04:20.584,0:04:23.707 John Cage realized[br]that people were losing the option 0:04:23.731,0:04:26.091 to shut out the background[br]music of the world. 0:04:26.457,0:04:30.337 He worried that Muzak would prevent people[br]from hearing silence altogether. 0:04:31.454,0:04:32.755 In 1948, 0:04:32.779,0:04:35.438 four years before he wrote "4'33''," 0:04:35.462,0:04:37.492 John Cage mentioned[br]that he wanted to write 0:04:37.516,0:04:40.025 a four-and-a-half-minute-long[br]piece of silence 0:04:40.049,0:04:42.461 and sell it to the Muzak company. 0:04:42.485,0:04:44.802 It started as something[br]of a political statement 0:04:44.826,0:04:46.795 or an offhand comment, 0:04:46.819,0:04:49.794 but this idea struck a nerve[br]and quickly evolved. 0:04:50.176,0:04:53.457 John Cage was starting to think[br]deeply about silence. 0:04:53.981,0:04:57.314 And when he visited a truly quiet place, 0:04:57.338,0:04:59.338 he made a startling discovery. 0:05:00.195,0:05:04.354 John Cage visited an anechoic chamber[br]at Harvard University. 0:05:04.378,0:05:07.078 Anechoic chambers are rooms[br]that are acoustically treated 0:05:07.102,0:05:09.553 to minimize sound to almost zero. 0:05:09.911,0:05:11.712 There are no sounds in these rooms, 0:05:11.736,0:05:14.587 so John Cage didn't expect[br]to hear anything at all. 0:05:15.101,0:05:18.147 But he actually heard[br]his own blood circulating. 0:05:18.171,0:05:19.851 (Pulse) 0:05:19.875,0:05:22.133 I've personally experienced[br]an anechoic chamber, 0:05:22.157,0:05:24.117 and it's a really wild experience 0:05:24.141,0:05:26.410 that can completely change[br]your perceptions 0:05:26.434,0:05:28.574 about sound and silence. 0:05:28.926,0:05:31.974 It really felt like my brain[br]just turning up an amplifier, 0:05:31.998,0:05:34.149 grasping for anything to hear. 0:05:34.575,0:05:35.853 Just like John Cage, 0:05:35.877,0:05:39.821 I could very clearly hear my blood[br]pushing through my body. 0:05:39.845,0:05:42.191 John Cage realized, in that moment, 0:05:42.215,0:05:46.350 that no matter where we are,[br]even our bodies are making sound. 0:05:46.790,0:05:50.544 There's basically no such thing[br]as true silence. 0:05:50.949,0:05:53.044 As long as you are in your body, 0:05:53.068,0:05:55.059 you're always hearing something. 0:05:55.538,0:05:58.561 This is where John Cage's interest[br]in chance and randomness 0:05:58.585,0:06:00.847 met his interest in silence. 0:06:01.260,0:06:04.627 He realized that creating an environment[br]with no distractions 0:06:04.651,0:06:06.704 wasn't about creating silence. 0:06:07.220,0:06:09.753 It wasn't even about controlling noise. 0:06:10.149,0:06:13.165 It was about the sounds[br]that were already there, 0:06:13.189,0:06:15.673 but you suddenly hear for the first time 0:06:15.697,0:06:18.030 when you're really ready to listen. 0:06:19.204,0:06:22.355 That's what's so often[br]misunderstood about "4'33''." 0:06:22.379,0:06:24.227 People assume it's a joke, 0:06:24.251,0:06:26.895 but that couldn't be further[br]from the truth. 0:06:26.919,0:06:29.212 It sounds different[br]everywhere you play it. 0:06:29.236,0:06:30.887 And that's the point. 0:06:30.911,0:06:33.752 What John Cage really wanted us to hear 0:06:33.776,0:06:36.848 is the beauty of the sonic[br]world around us. 0:06:36.872,0:06:40.124 (Birds chirping) 0:06:40.785,0:06:45.166 (Overlapping voices) 0:06:45.190,0:06:49.037 (Church bell ringing) 0:06:49.061,0:06:53.227 (Crickets chirping and owl hooting) 0:06:53.982,0:06:56.339 "4'33''" should be a mindful experience 0:06:56.363,0:07:00.264 that helps you focus on accepting things[br]just the way they are. 0:07:00.590,0:07:04.629 It's not something that anyone else[br]can tell you how you're supposed to feel. 0:07:04.653,0:07:06.053 It's deeply personal. 0:07:06.542,0:07:08.915 It also brings up[br]some pretty big questions 0:07:08.939,0:07:10.505 about our sonic world. 0:07:10.831,0:07:13.362 Is "4'33''" music, is it sound, 0:07:13.386,0:07:14.879 is sound music? 0:07:14.903,0:07:16.545 Is there even a difference? 0:07:16.919,0:07:18.497 John Cage reminds us 0:07:18.521,0:07:22.235 that music isn't the only kind of sound[br]worth listening to. 0:07:22.546,0:07:24.946 All sounds are worth thinking about. 0:07:25.339,0:07:27.717 We have a once-in-a-lifetime opportunity 0:07:27.741,0:07:29.513 to reset our ears. 0:07:29.839,0:07:32.609 And if we become more conscious[br]of what we hear, 0:07:32.633,0:07:35.402 we'll inherently make[br]our world sound better. 0:07:36.149,0:07:40.117 Quietness is not when we turn off[br]our minds to sound, 0:07:40.585,0:07:42.589 but when we can really start to listen 0:07:42.613,0:07:45.746 and hear the world[br]in all of its sonic beauty. 0:07:46.184,0:07:47.807 So in this spirit, 0:07:47.831,0:07:50.418 let's perform "4'33''" together, 0:07:50.442,0:07:51.974 wherever you are. 0:07:51.998,0:07:53.156 It's three movements, 0:07:53.180,0:07:55.014 and I'll let you know when they start. 0:07:55.038,0:07:58.650 Listen to the texture and rhythm[br]of the sounds around you right now. 0:07:59.037,0:08:00.664 Listen for the loud and soft, 0:08:00.688,0:08:02.498 the harmonic, the dissonant, 0:08:02.522,0:08:06.331 and all the small details[br]that make every sound unique. 0:08:06.668,0:08:11.831 Spend this time as mindful and focused[br]in this real-life sonic moment. 0:08:12.279,0:08:15.831 Enjoy the magnificence[br]of hearing and listening. 0:08:16.331,0:08:18.264 So here comes the first movement. 0:08:18.288,0:08:19.621 Starting ... 0:08:19.645,0:08:21.038 now. 0:08:21.062,0:08:22.213 [I. Tacet] 0:08:22.237,0:08:23.387 (No audio) 0:08:50.158,0:08:51.758 And here's movement two. 0:08:51.782,0:08:54.315 It will be two minutes and 23 seconds. 0:08:54.952,0:08:56.103 [II.
