1 00:00:00,000 --> 00:00:21,160 Hello everyone, I'm Steve Marshall. 2 00:00:21,160 --> 00:00:25,280 I was last here in 2016. 3 00:00:25,280 --> 00:00:29,320 I spent seven years researching a book about Avery. 4 00:00:29,320 --> 00:00:31,719 I used to live very close to Avery. 5 00:00:31,719 --> 00:00:36,200 For ten years I lived in Yates Bridge, a couple of miles away. 6 00:00:36,200 --> 00:00:44,799 I used to go out every day, walking the landscape and conducting my research. 7 00:00:44,799 --> 00:00:52,719 This culminated in my book, Exploring Avery, the Essential Guide, which is for sale... 8 00:00:52,719 --> 00:00:56,519 of here, £15. 9 00:00:56,520 --> 00:01:01,680 I was pleased with the book, very pleased with it, despite having 400 illustrations 10 00:01:01,680 --> 00:01:05,000 and 200 something pages. 11 00:01:05,000 --> 00:01:10,400 I had so much research that I'd accumulated in that seven year period. 12 00:01:10,400 --> 00:01:16,400 It couldn't actually fit it in the book, so I had to make a huge website which has 13 00:01:16,400 --> 00:01:18,600 all the extra information in it. 14 00:01:18,600 --> 00:01:23,920 It's a good resource for anyone interested in Avery. 15 00:01:23,960 --> 00:01:33,040 The work I did was all very scientific and was endorsed by many Avery archaeologists. 16 00:01:33,040 --> 00:01:38,000 It didn't include a side of Avery that many people think is more important. 17 00:01:38,000 --> 00:01:42,159 Lots of the people who visit Avery, again and again, sometimes people visit several 18 00:01:42,159 --> 00:01:48,760 times a year, they're not interested in soil horizons and carbon dating. 19 00:01:48,760 --> 00:01:55,120 What I love about Avery is its atmosphere and its mystical qualities. 20 00:01:55,120 --> 00:01:57,040 I just couldn't fit any of that in the book. 21 00:01:57,040 --> 00:02:01,920 There wasn't space and it's not something I'm good at writing about. 22 00:02:01,920 --> 00:02:09,719 So I decided to follow up the book with something quite different. 23 00:02:09,719 --> 00:02:16,080 Let's just have a look at the book first. 24 00:02:16,080 --> 00:02:19,360 I'll give you an idea of what's in the book. 25 00:02:28,960 --> 00:02:42,280 So from that I went to Avery's transcripts, an album of music, which to me expresses 26 00:02:42,280 --> 00:02:45,160 Avery's mystical side. 27 00:02:45,240 --> 00:02:50,599 This seems a bit of an odd leap, I know, but I spent most of my life as a film composer. 28 00:02:50,599 --> 00:02:57,639 I did scores for hundreds and hundreds of documentaries, wildlife, travel, anthropology 29 00:02:57,639 --> 00:03:04,439 programmes and for a while I worked in the BBC Radiophonic Workshop where they used 30 00:03:04,439 --> 00:03:08,280 to make the Doctor Who music. 31 00:03:08,280 --> 00:03:14,079 So expressing things musically comes more naturally to me really than writing. 32 00:03:14,080 --> 00:03:20,520 So I'm going to talk to you about just a small part of this album. 33 00:03:20,520 --> 00:03:27,439 Like the book, it covered all the different areas of Avery, which is the whole sequence 34 00:03:27,439 --> 00:03:31,080 of monuments and the landscape as well is equally important. 35 00:03:31,080 --> 00:03:36,480 So there are ten tracks on the album and each one is for a different aspect or different 36 00:03:36,480 --> 00:03:39,680 monuments of the Avery complex. 37 00:03:39,680 --> 00:03:43,280 I could go on about it for hours but you're lucky I've only got half an hour. 38 00:03:48,480 --> 00:03:55,439 So I'm a bit disturbed here because I'm seeing a view of PowerPoint that I don't... 39 00:03:55,439 --> 00:03:58,960 get and it's a little bit confusing. 40 00:03:58,960 --> 00:04:02,319 I'm getting the hang of it now. 41 00:04:02,319 --> 00:04:07,480 The track that you heard when we were testing the sound there was Windmill Hill. 42 00:04:08,280 --> 00:04:10,919 It was one of the loveliest places around Avery. 43 00:04:10,919 --> 00:04:19,240 It was the first occupied place from about 5000 BC and cattle herders used to meet there 44 00:04:19,240 --> 00:04:22,920 and bring their cattle and trade them and feast on them. 45 00:04:22,920 --> 00:04:30,599 So that's why you heard cattle lowing in that track. 46 00:04:30,599 --> 00:04:36,000 In the album you incorporate something called binaural recording. 47 00:04:36,000 --> 00:04:39,000 This is not the same as binaural beats. 48 00:04:39,000 --> 00:04:44,199 Binaural beats is a way of changing your mental state through sound. 49 00:04:44,199 --> 00:04:50,319 Binaural recording is almost like calligraphy with picture. 50 00:04:50,319 --> 00:04:54,839 If you record with a model of a human head with microphones clipped on the side where 51 00:04:54,839 --> 00:05:01,879 its ears should be or if you do as I generally do, putting microphones in your... 52 00:05:01,879 --> 00:05:10,079 atwards, then the recording is spatially encoded just like a hologram is. 53 00:05:10,079 --> 00:05:16,040 When you play back on headphones you'll hear 360 degree sound all around you, above and 54 00:05:16,040 --> 00:05:17,040 below. 55 00:05:17,040 --> 00:05:22,040 I've been doing this for decades. 56 00:05:22,040 --> 00:05:29,000 I had lots of recordings made in the Avery area, inside the monuments as well. 57 00:05:29,000 --> 00:05:35,160 If you play the album on headphones you'll hear things like birds flying above your head 58 00:05:35,160 --> 00:05:38,439 or birds flocking through the trees that are not there. 59 00:05:38,439 --> 00:05:46,439 There's a thunderstorm above your head and some of the rhythmic sounds move around... 60 00:05:46,439 --> 00:05:47,439 you. 61 00:05:47,439 --> 00:05:56,439 It's a different listening experience than what you may have heard before. 62 00:05:57,199 --> 00:06:02,199 The track I began with was the Sanctuary. 63 00:06:02,199 --> 00:06:09,199 I don't know if you know the Sanctuary, east of Avery, on the side of the Afall. 64 00:06:09,199 --> 00:06:12,199 That's how it looks today. 65 00:06:12,199 --> 00:06:19,199 It's been described as one of Britain's least spectacular archaeological sites, perhaps 66 00:06:19,199 --> 00:06:23,199 second only to Woodhenge. 67 00:06:23,199 --> 00:06:27,199 It is very similar to Woodhenge in that it looks really dull. 68 00:06:27,199 --> 00:06:32,199 All there is is a series of painted concrete posts put there by the Ministry of Works in 69 00:06:32,199 --> 00:06:33,199 1950. 70 00:06:33,199 --> 00:06:36,199 It's actually fascinating. 71 00:06:36,199 --> 00:06:40,199 There are two hippies there for scale in the picture. 72 00:06:40,199 --> 00:06:44,199 Where they're sitting, that was the size of the original monument. 73 00:06:44,199 --> 00:06:50,199 It was a series of concentric rings of wooden posts which obviously rotted. 74 00:06:50,199 --> 00:06:55,199 Before they rotted, standing stones were put in position to mark where the circle 75 00:06:55,199 --> 00:06:56,199 had been. 76 00:06:56,199 --> 00:07:02,199 But because it was rather unimposing, they then put another circle around it, twice 77 00:07:02,199 --> 00:07:03,199 the size. 78 00:07:03,199 --> 00:07:10,199 What I was interested in was the geometry of the original monument. 79 00:07:10,199 --> 00:07:19,199 It may have looked like this with plain posts, or there may have been tree trunks,... 80 00:07:19,199 --> 00:07:23,199 there may have been upside down even with the roots sticking in there. 81 00:07:23,199 --> 00:07:28,199 Or it may have been like this, like Stonehenge-like with lintels. 82 00:07:28,199 --> 00:07:32,199 You can see there the concentric rings of posts. 83 00:07:32,199 --> 00:07:37,199 The smaller posts on the outside seem to have been a fence to keep animals out. 84 00:07:37,199 --> 00:07:45,199 If you look at it in plan, you can see it as a series of overlaid regular polygons. 85 00:07:45,199 --> 00:07:50,199 From the middle outwards, that's 6, 8, 12 and 16 sides. 86 00:07:50,199 --> 00:07:55,199 So I find geometry rather difficult to understand. 87 00:07:55,199 --> 00:07:57,199 Visually anyway. 88 00:07:57,199 --> 00:08:03,199 So I decided I could do this musically by dividing the time into 6, 8, 12 and 16. 89 00:08:03,199 --> 00:08:07,199 I'll play you a little clip so you can see what I mean. 90 00:08:07,199 --> 00:08:10,199 There's all the posts in plan. 91 00:08:10,199 --> 00:08:12,199 Here's the music. 92 00:08:15,199 --> 00:08:17,199 6 93 00:08:22,199 --> 00:08:24,199 8 94 00:08:30,199 --> 00:08:32,200 12 95 00:08:38,200 --> 00:08:40,200 16 96 00:08:45,200 --> 00:08:47,200 17 97 00:08:49,200 --> 00:08:56,200 So to get the idea, I'm trying to put across ideas in archaeology in just a different way, 98 00:08:56,200 --> 00:09:00,200 by looking at things sideways. 99 00:09:00,200 --> 00:09:10,200 Another track is called Bone Ceremony, and it's based on the West Kennet long bar. 100 00:09:10,200 --> 00:09:18,200 There's the West Kennet long barrow. 101 00:09:18,200 --> 00:09:20,200 100 metres long. 102 00:09:20,200 --> 00:09:25,200 At one end of it there's these small chambers made of sarsen stone. 103 00:09:25,200 --> 00:09:30,200 I've done a presentation here about the acoustics of the barrow a few years ago. 104 00:09:30,200 --> 00:09:38,200 There's a central passage with a chamber at the end of it, and 4 more chambers, 2 at e... 105 00:09:38,200 --> 00:09:46,200 There's an intrasonic resonance in the main chamber, in the central passage, 106 00:09:46,200 --> 00:09:51,200 which can be excited by whirling a bullroarer. 107 00:09:51,200 --> 00:09:58,200 I'm very interested in bullroars, and I'm sure they were used in the Neolithic since... 108 00:09:58,200 --> 00:10:03,200 Here's a picture of some bullroars. 109 00:10:04,200 --> 00:10:10,200 These are in the amazing Pitt Rivers Museum in Oxford, and they're from Papua New Guinea. 110 00:10:10,200 --> 00:10:15,200 But every culture in the world has invented the bullroarer independently. 111 00:10:15,200 --> 00:10:20,200 They're generally made of wood and fish shaped, a piece of string tied on one end, 112 00:10:20,200 --> 00:10:32,200 and you whirl the thing around your head, and as it whirls it spins on its axis and... 113 00:10:32,200 --> 00:10:38,200 Because it makes such low frequencies, if you whirl this in the mouth of the longbarrow, 114 00:10:38,200 --> 00:10:41,200 it's a bit like blowing across the neck of a bottle. 115 00:10:41,200 --> 00:10:47,200 You get this low frequency, which you can't hear, but it can change your mental state. 116 00:10:47,200 --> 00:10:54,200 You get the impression that someone's standing behind you, or some people have... 117 00:10:54,200 --> 00:10:57,200 It's quite dramatic. 118 00:10:58,200 --> 00:11:09,200 Here's me outside my house, wearing a bullroarer that's got coloured LEDs fixed ... 119 00:11:09,200 --> 00:11:27,200 In many cultures it's known as the voice of the ancestors, the sound of the bullroarer. 120 00:11:27,200 --> 00:11:38,200 So what I imagine, like many archaeologists, I think that longbarrows were used for mor... 121 00:11:38,200 --> 00:11:48,200 I think they were used as centres for initiation into tribal customs or rites of... 122 00:11:51,200 --> 00:11:56,200 And as well as that low frequency resonance, there are musical resonances. 123 00:11:56,200 --> 00:12:00,200 There's the burrowing plan, and you can see where it says E and A. 124 00:12:00,200 --> 00:12:06,200 That's the note that those chambers naturally resonate at. 125 00:12:06,200 --> 00:12:10,200 If you're going to make any kind of a sound, you'll hear that note. 126 00:12:10,200 --> 00:12:16,200 The first two are a low E, which is a note I couldn't sing until I was in my 50s. 127 00:12:16,200 --> 00:12:23,200 So it's interesting that if people were used to resonate in these chambers, they'd be... 128 00:12:23,200 --> 00:12:27,200 They'd certainly be unusually old for their time. 129 00:12:27,200 --> 00:12:33,200 So you can hear the low E's. These are recorded inside the burrow itself. 130 00:12:37,200 --> 00:12:41,200 That's the E, and then above that's the A. 131 00:12:46,200 --> 00:12:52,200 So throughout this piece of music, you can hear the two together, E and the A. 132 00:12:52,200 --> 00:13:10,200 Now, if in my imaginary scenario, young people who were in their early teens perhaps, 133 00:13:10,200 --> 00:13:16,200 I put in the end chamber, which has literally got the bones of their ancestors with them, 134 00:13:16,200 --> 00:13:25,200 when one Victorian archaeologist dug into the burrow, he discovered a skeleton that was... 135 00:13:25,200 --> 00:13:31,200 So if people were in there, they'd be sat literally with their great-great-grandfather, 136 00:13:31,200 --> 00:13:40,200 they'd have been prepared for the experience, perhaps given magic mushrooms, perhaps... 137 00:13:40,200 --> 00:13:45,200 So they'd be really primed for some strange experience. 138 00:13:45,200 --> 00:13:50,200 But presumably there'd be someone conducting this ceremony. 139 00:13:50,200 --> 00:13:56,200 So I imagine some kind of priest or shaman with an incantation. 140 00:13:56,200 --> 00:13:58,200 What would that sound like? 141 00:13:58,200 --> 00:14:04,200 Well, it's very likely to have spoken something like Proto-Indo-European, 142 00:14:04,200 --> 00:14:13,200 which is a language that's been slowly pieced together from surviving fragments over the... 143 00:14:13,200 --> 00:14:19,200 So we assume that the priest probably spoke Proto-Indo-European. 144 00:14:19,200 --> 00:14:24,200 Well, that's quite handy for me, because I've got a dictionary for Proto-Indo-European. 145 00:14:24,200 --> 00:14:31,200 And from little snippets in there, I managed to put together an imaginary ceremony. 146 00:14:31,200 --> 00:14:34,200 Translated into English, it is, 147 00:14:34,200 --> 00:14:39,200 Sky Father, Holy Earth Mother, God-inspired, powerful me and magic force, 148 00:14:39,200 --> 00:14:42,200 Dream and remember, dream and truly see, 149 00:14:42,200 --> 00:14:45,200 The bright lights in this place of darkness, 150 00:14:45,200 --> 00:14:47,200 Earth and stone, rock and bone, 151 00:14:47,200 --> 00:14:50,200 Rain and river, springs and blood, 152 00:14:50,200 --> 00:14:52,200 Sun and moon, wind and fire, 153 00:14:52,200 --> 00:14:56,200 Dream and truly see, you sons and daughters, dream and truly see, 154 00:14:56,200 --> 00:15:00,200 Dream and remember, dream and truly see. 155 00:15:00,200 --> 00:15:06,200 And I recorded that inside the long barrow, where you can hear the resonances affectin... 156 00:15:06,200 --> 00:15:13,200 New year's father, Earthbound cycles, what is this house, who are those units? 157 00:15:13,200 --> 00:15:19,200 So it is fair, so it is right, who does this business? 158 00:15:19,200 --> 00:15:47,200 You can hear how the voice has got that note to it, the two notes which come from the... 159 00:15:47,200 --> 00:15:50,200 So I used that. 160 00:15:57,200 --> 00:16:04,200 So I started with some sounds of owls that were recorded just outside Avebury, 161 00:16:04,200 --> 00:16:10,200 and then the bull-roarers, and then the incantation. 162 00:16:17,200 --> 00:16:24,200 So I started with some sounds of owls that were recorded just outside Avebury, 163 00:16:24,200 --> 00:16:27,200 and then the incantation. 164 00:16:47,200 --> 00:16:54,200 So you can hear that is how the track starts, 165 00:16:54,200 --> 00:16:58,200 and that pulse that comes in on the synthesizers, 166 00:16:58,200 --> 00:17:02,200 that is a particular tempo for one good reason. 167 00:17:02,200 --> 00:17:07,200 To get that mind-altering effect of the resonance of the passage, 168 00:17:07,200 --> 00:17:10,200 you can either resonate the passage directly, 169 00:17:10,200 --> 00:17:16,200 or you can drum at the frequency that it resonates at. 170 00:17:16,200 --> 00:17:21,200 This is very low frequencies, 9 Hz, 9 times a second, 171 00:17:21,200 --> 00:17:26,200 which is too low to be heard, but for a drummer it is quite playable. 172 00:17:26,200 --> 00:17:34,200 So as the track develops, some drumming comes in, 173 00:17:34,200 --> 00:17:40,200 which is quite in keeping for Neolithic people. 174 00:17:40,200 --> 00:17:45,200 And the ceremony works. 175 00:17:45,200 --> 00:17:49,200 The two of the ancestors come zooming down. 176 00:17:49,200 --> 00:17:54,200 If you hear it on headphones, it is actually fireworks backwards, 177 00:17:54,200 --> 00:17:57,200 so you will hear this whoosh come down, 178 00:17:57,200 --> 00:18:00,200 and the people announce themselves in Proto-Indo-European, 179 00:18:00,200 --> 00:18:04,200 I am your grandmother, I am your great-great-grandmother, 180 00:18:04,200 --> 00:18:07,200 I am your great-great-grandfather. 181 00:18:07,200 --> 00:18:11,200 So they introduce themselves, and then they turn into a flock of rogues, 182 00:18:11,200 --> 00:18:14,200 and fly off into the sky. 183 00:18:14,200 --> 00:18:17,200 It is quite psychedelic actually. 184 00:18:17,200 --> 00:18:21,200 So I will play you the end section of Bone Ceremony. 185 00:18:30,200 --> 00:18:33,200 Probably. 186 00:20:01,200 --> 00:20:04,200 So off we go as a flock of rogues. 187 00:20:04,200 --> 00:20:07,200 So you are getting the idea. 188 00:20:07,200 --> 00:20:09,200 That was Bone Ceremony. 189 00:20:09,200 --> 00:20:12,200 And the last track I am going to talk about 190 00:20:12,200 --> 00:20:17,200 is about the Avery Great Henge itself, called Great Circle. 191 00:20:20,200 --> 00:20:24,200 There is the Great Circle, the amazing Avery Henge, 192 00:20:24,200 --> 00:20:27,200 a quarter of a mile across, 193 00:20:27,200 --> 00:20:30,200 obviously it has got roads running through it today. 194 00:20:30,200 --> 00:20:34,200 If we can imagine what Avery was like thousands of years ago 195 00:20:34,200 --> 00:20:37,200 with no roads, and no houses or trees, 196 00:20:37,200 --> 00:20:41,200 and no cars going past, and airplanes and buses, 197 00:20:41,200 --> 00:20:44,200 it would have been quite a different place. 198 00:20:44,200 --> 00:20:48,200 If you were to make a sound in the centre of Avery, 199 00:20:48,200 --> 00:20:51,200 say by clicking a pair of sticks together, 200 00:20:51,200 --> 00:20:56,200 you would hear an echo coming back from the bank of the Henge, 201 00:20:56,200 --> 00:21:00,200 and the salsum stones that are erected all around it. 202 00:21:00,200 --> 00:21:04,200 So that sounds, when you click where the red dot is, 203 00:21:04,200 --> 00:21:08,200 the sound is travelling out to the edge of the Henge, 204 00:21:08,200 --> 00:21:10,200 coming back again. 205 00:21:10,200 --> 00:21:14,200 It is travelling a quarter of a mile, so that is a very slow echo. 206 00:21:14,200 --> 00:21:19,200 But inside the Henge were two smaller stone circles. 207 00:21:19,200 --> 00:21:23,200 This should probably be called rings, 208 00:21:23,200 --> 00:21:27,200 because one of them was slightly egg-shaped. 209 00:21:27,200 --> 00:21:30,200 But they are about 100 metres across. 210 00:21:30,200 --> 00:21:33,200 If you were to stand where the dots are and click, 211 00:21:33,200 --> 00:21:38,200 you would get an echo, which would be louder than that from the outer circle, 212 00:21:38,200 --> 00:21:41,200 but much shorter. 213 00:21:41,200 --> 00:21:44,200 I didn't realise until I started doing this album 214 00:21:44,200 --> 00:21:49,200 that the two echoes are so related in time. 215 00:21:49,200 --> 00:21:53,200 The echo of the great circle is exactly four times the length 216 00:21:53,200 --> 00:21:56,200 of the echo from the smaller circles, 217 00:21:56,200 --> 00:21:59,200 which is perfect if you are trying to make a piece of music, 218 00:21:59,200 --> 00:22:02,200 because immediately you have got a rhythm. 219 00:22:02,200 --> 00:22:06,200 So if you click my sticks in the middle, 220 00:22:10,200 --> 00:22:12,200 that is the short echo. 221 00:22:12,200 --> 00:22:16,200 Here is the long echo. 222 00:22:16,200 --> 00:22:21,200 So if you use the two together, you are getting into a rhythm. 223 00:22:40,200 --> 00:22:43,200 So the tempo and the rhythm of the track are taken directly 224 00:22:43,200 --> 00:22:46,200 from the proportions of the Henge itself. 225 00:22:46,200 --> 00:22:49,200 I have used lots of dancing harmonics as well, 226 00:22:49,200 --> 00:22:54,200 since harmonics are the building blocks of the universe, I think. 227 00:22:59,200 --> 00:23:03,200 I wanted to give the whole thing a sense of circularity, 228 00:23:03,200 --> 00:23:06,200 to emphasise that thing of it being a great circle. 229 00:23:06,200 --> 00:23:10,200 So I have built this contraption in my garage. 230 00:23:10,200 --> 00:23:17,200 It is like a big wooden cross with speakers attached to the four ends. 231 00:23:17,200 --> 00:23:22,200 The whole thing was suspended from the ceiling in my garage. 232 00:23:22,200 --> 00:23:26,200 I played back parts of the track, 233 00:23:26,200 --> 00:23:29,200 whilst this thing was slowly revolving, 234 00:23:29,200 --> 00:23:32,200 with microphones in my ears. 235 00:23:32,200 --> 00:23:35,200 When you play it back on headphones, 236 00:23:35,200 --> 00:23:38,200 you can hear the sounds travelling behind you. 237 00:23:38,200 --> 00:23:41,200 It is very circular. 238 00:23:41,200 --> 00:23:44,200 It is unusual, but it works. 239 00:23:49,200 --> 00:23:52,200 That was me recording it. 240 00:23:55,200 --> 00:24:00,200 I am going to play you now an edited version of the track, 241 00:24:00,200 --> 00:24:05,200 with a little video together from all the thousands of photographs and videos 242 00:24:05,200 --> 00:24:08,200 I have taken inside Avebury. 243 00:24:08,200 --> 00:24:11,200 It flickers, it flickers a lot. 244 00:24:11,200 --> 00:24:14,200 So if you are epileptic, or you have any problems with that, 245 00:24:14,200 --> 00:24:17,200 apologies, please look away. 246 00:24:21,200 --> 00:24:24,200 So here is Great Circle. 247 00:24:35,200 --> 00:24:38,200 So here is Great Circle. 248 00:25:05,200 --> 00:25:08,200 So
