:00:00. > :00:00.pages of the morning papers. More on the website. We will have a full
:00:00. > :00:33.bulletin at two o'clock. Now on BBC News, it's time for Click.
:00:34. > :00:39.This week 's Click will be music to your ears, hopefully, as we play the
:00:40. > :00:45.technology that can make a fortune out of energy falls `` anything. We
:00:46. > :00:50.will meet the hackers creating music for everyone's tastes. And we will
:00:51. > :00:54.meet the man who made it his mission to digitise a real classic. All of
:00:55. > :01:04.that, plus the latest technology news, and something fresh.
:01:05. > :01:08.Welcome to Click, I am Spencer Kelly. This week 's programme has a
:01:09. > :01:16.musical motive, so I came to the home of the Proms, the Royal Albert
:01:17. > :01:20.Hall. Since the hall opened in 1871, a white writing of different
:01:21. > :01:28.acts has graced the stage, from classical orchestras to electron at
:01:29. > :01:33.her `` electronic. Excuse the rehearsals, I have a show to put on
:01:34. > :01:37.tonight. The Albert Hall does not only play host to musicians and
:01:38. > :01:42.performers, but a digital classroom will open for the public which aims
:01:43. > :01:51.to explore and teach more about the links between music technology and
:01:52. > :01:56.science. In an attempt to make this venue relevant, the halls education
:01:57. > :01:59.team has created special applications which demonstrate the
:02:00. > :02:03.importance of maths to music. Within the tablets themselves, the kids can
:02:04. > :02:09.use applications we have created where we can get them to tap into,
:02:10. > :02:14.using their pens, music notes. Then they can create fractions, and then
:02:15. > :02:19.they can create beats. Then, we can record those beats with the sound,
:02:20. > :02:23.and they will have a brilliant piece of music to take home. The
:02:24. > :02:27.satisfaction of doing that and creating music digitally, they
:02:28. > :02:32.should be impressed! Tablets, one way to inspire the new generation of
:02:33. > :02:36.maestros that could one day take to the stage. In fact, technology is
:02:37. > :02:49.being used to help them collaborate on all sorts of bizarre
:02:50. > :02:54.compositions. Hacker`thon. The concept is simple, when we went to
:02:55. > :02:58.Boston recently, we visited a special one. One dedicated to music
:02:59. > :03:08.technology. And, they did not do too badly. This is MJ, a pan piping
:03:09. > :03:15.beatbox. He has popped him to see how things are going at the music
:03:16. > :03:20.Tech Fest Hackerthon. It is a convention that rings together the
:03:21. > :03:24.most creative and eccentric music technologists on the planet, and is
:03:25. > :03:29.famous for its 24 hour session which I am going to enter. Last year 's
:03:30. > :03:36.winner made this. Adam John Williams had a guitar make a whole new noise
:03:37. > :03:40.by adding an accessory. My mission is to hack something musically
:03:41. > :03:43.awesome and make it through 24 hours of hard`core coding. Along with the
:03:44. > :03:51.obligatory pizza. Some people have come here with ideas in mind, like
:03:52. > :03:57.Sean, he is a gifted musician, biomedical researcher, Coda, and
:03:58. > :04:01.fire dancer. That is a dragon staff. I want to put rotational sensors on
:04:02. > :04:11.it. To make that work, this designer will help him to 3`D print a micro`
:04:12. > :04:16.sensor. It sounds like fun but I do not have ideas yet. Ten hours in, we
:04:17. > :04:21.move to a TV studio up the road for the overnight segment. It is a cool
:04:22. > :04:28.venue with a stage, musicians, and a roomful of kit to stream content to
:04:29. > :04:33.live on the web. Tonight, it is rammed with Brit controllers,
:04:34. > :04:37.computers, and hackers, wherever we can fit. In the back room, James is
:04:38. > :04:39.making a guitar controller with nifty coding, and he is making a
:04:40. > :04:45.guitar controller with nifty coding, and Houston to plate. He is using a
:04:46. > :04:52.programme which is used a lot in media applications. `` and is using
:04:53. > :04:56.a paper plate. It is passed our bedtime, so to keep up our energy,
:04:57. > :05:07.we take to the stage for loud brainstorming. (FUNKY MUSIC) back to
:05:08. > :05:11.work, one of my stage cohorts was this man, a hacker specialising in
:05:12. > :05:17.machine generated music and the user could therapy. He is working on a 16
:05:18. > :05:25.legged music controller, made from a painting. `` musical therapy. I want
:05:26. > :05:32.this to be my instrument. It is 4am. I compose music for it, it has
:05:33. > :05:36.16 legs, and a head. It is fun collaborating! If you come to the
:05:37. > :05:45.festival, and collaborate with another wonderful mind, who has been
:05:46. > :05:49.researching something different, some in magical can happen. The 3`D

:06:01. > :06:03.controller to conduct the paint segments and connect them to a
:06:04. > :06:09.computer. I am working out whether standing up all night is putting up
:06:10. > :06:15.barriers to creativity or making us crazy. It could be both! Finally,
:06:16. > :06:19.inspiration struck over breakfast, when I said a doughnut tasted like D
:06:20. > :06:25.Major. For the first time in my life, people heard it, and thought"
:06:26. > :06:35.dataset" . They asked me more questions and I ate donors! `` eight
:06:36. > :06:43.more doughnuts. My senses are mixed together a bit, I hear music when I
:06:44. > :06:47.eat things. Yes, really! The developers liked this idea, and
:06:48. > :06:53.together, we made an application which pairs food and music. We are
:06:54. > :06:56.going to build it. Alex is using a programme which is like a sketch pad
:06:57. > :07:01.for working out what an apt mallet to look like, and helps us imagine
:07:02. > :07:09.the layout and what we would like to do `` an application. I am working
:07:10. > :07:12.on which data is requested and how the application and user will
:07:13. > :07:26.interact. I am finally hacking at Hackerthon! It feels so good. We are
:07:27. > :07:31.nearing the 24`hour mark. And... We have an application! We finished the
:07:32. > :07:39.first draft in time. We went back to Microsoft research to present our
:07:40. > :07:54.idea. SoundBites. Three, two, one, eat! (PIANO MUSIC PLAYS) now you
:07:55. > :07:57.have that spiciness. After 24 hours of being awake, I am not tired but
:07:58. > :08:02.excited to see whatever one else has come up with. Sean's dragon staff
:08:03. > :08:11.works a treat, and the faster he spins it, the faster the music
:08:12. > :08:16.plays. CJ's controller is a triumph. My team won one of the top prizes
:08:17. > :08:19.for our application. We are continuing to work on it together,
:08:20. > :08:26.making me a fully fledged music hacker. Watch this space!

:12:28. > :12:31.Plenty of musicians these days use tablets in their setup, I thought I
:12:32. > :12:36.would show you this. A neat little application. You draw your picture
:12:37. > :12:50.and record your voice at the same time, like this. " la la la la la la
:12:51. > :13:04.la la la la close quotes. Brilliant, I know. I'm sure we can all see the
:13:05. > :13:11.point of that. Now, we are getting to grips with some other technology
:13:12. > :13:16.that uses the human voice. If you always wanted to master the
:13:17. > :13:23.violin, but could never get your head around learning to play, there
:13:24. > :13:31.could be hoped for you. This application allows you to shoot like
:13:32. > :13:38.a trumpet or low like a base by using your voice. This is to allow
:13:39. > :13:45.for people to get ideas out of their head, without needing the dexterity
:13:46. > :13:50.to play an instrument. It sounds great, but to put it to the test, we
:13:51. > :13:53.invited singers from a range of genres to take part in an improvised
:13:54. > :14:09.live performance in the BBC's Live Lounge. From Kelly, hard`core scream
:14:10. > :14:24.and, Joe, folk artist Elle, and death metal rocker Alex. I decided
:14:25. > :14:31.to join in as my operatic alter ego, Madame Eleanora Genara. Without
:14:32. > :14:45.microphones connected to a laptop and the application fired up, let
:14:46. > :14:50.the vocal harmony commence. OK, if you are not wearing headphones, it
:14:51. > :14:53.is hardly a modern`day masterpiece, at hearing the complete composition
:14:54. > :15:12.through the software sounds infinitely more impressive. The
:15:13. > :15:15.magic of the application is that it works by using a microphone as
:15:16. > :15:22.immediate input, and an algorithm identifies the pitch at superspeed
:15:23. > :15:28.and assigns a note to your voice. This note can be played out as any
:15:29. > :15:32.digital instrument with no latency, meaning you can get almost immediate
:15:33. > :15:39.feedback while you perform. I see it as something that could be a tool
:15:40. > :15:43.for learning and raw creativity. There are still a few things to iron
:15:44. > :15:48.out in this version, namely, how to tweak the settings to deal with
:15:49. > :15:52.screaming death metal musicians and percussion sounds. They are harder
:15:53. > :16:00.for machines to pitch. But it is easy to get carried away. Times up!
:16:01. > :16:14.Out! Even the rehearsals are pretty mind
:16:15. > :16:21.blowing, let me tell you. For years, technology has really struggled to
:16:22. > :16:27.reproduce those. Real instruments. One of the most challenging has
:16:28. > :16:30.always been the piano. With more powerful machines these days, it has
:16:31. > :16:33.become possible to fall out human ears. That is, it has become
:16:34. > :16:36.possible to fall out human ears. That has come at a cost, human
:16:37. > :16:52.effort. From Boston, Joe explains his musical journey.
:16:53. > :16:55.This is the main page of Ivory, and we have a range of features where
:16:56. > :17:01.you can select the kind of piano you want. You can hear the pedal noise,
:17:02. > :17:08.so we can turn pedal noise off or on. The sound quality is another
:17:09. > :17:14.level beyond conventional digital keyboards, because we take advantage
:17:15. > :17:22.of the faster processor speed, and the larger memory. And larger sample
:17:23. > :17:25.sizes, and those sorts of things. I had worked for a hardware
:17:26. > :17:35.synthesising manufacturer for almost 20 years, so I made digital
:17:36. > :17:39.keyboards and digital pianos, as did my partner in crime. We were
:17:40. > :17:44.constrained by the limitations that the instruments have. We didn't have
:17:45. > :17:49.a lot of memory, and one instrument I did for them, which was very
:17:50. > :17:58.successful, had a 1 megabyte piano. Our latest piano is 49 GB. It
:17:59. > :18:08.basically goes like this. Play a note... And let it became to
:18:09. > :18:15.silence. And there is no talking like I'm doing now. There is no
:18:16. > :18:19.moving, there is no breathing. It is about as tedious and boring as it
:18:20. > :18:24.looks, because you have to do this multiple times for every key, at
:18:25. > :18:33.every conceivable velocity level. The softest, the loudest. Other
:18:34. > :18:37.musicians think I must be crazy, it must be torture. And they are right,
:18:38. > :18:40.it is taught. Some people think it might be interesting, I would like
:18:41. > :18:44.to go to wait sampling session sometime, sometimes they say.
:18:45. > :18:55.Usually, an hour later they want to leave. I am willing to say, never
:18:56. > :18:58.weaken quite literally replicate the experience of sitting behind a
:18:59. > :19:05.physical instrument, but this physical instrument will never be
:19:06. > :19:09.able to quite do what Ivory can do, which is to put several instruments
:19:10. > :19:15.at our fingertips. A man on a musical mission. Time for Webscape.
:19:16. > :19:22.Did you know that Google handles and around 12.5 billion search request
:19:23. > :19:26.every month? It is not the only service to offer to uncover those
:19:27. > :19:33.hidden online gems, as Kate Russell has been finding out.
:19:34. > :19:39.Web search queries tend to work best if they are very little. But if you
:19:40. > :19:44.take the genre and give it a metaphorical twist, you can uncover
:19:45. > :19:48.some very interesting things. Yossarian Lives is an experimental
:19:49. > :19:53.search tool, allowing you to search for things metaphorically. That
:19:54. > :19:58.means you can find the conceptual distance that the results should be
:19:59. > :20:07.from your query term. You can save your result and add your
:20:08. > :20:11.interpretation of the metaphor. There is no disputing Google's are
:20:12. > :20:17.to dominance in the search sector. It handled over 2 trillion search
:20:18. > :20:21.queries last year, and over a billion people use it to search
:20:22. > :20:25.every month. You will get a lot of results if you query Google. But,
:20:26. > :20:34.perhaps not the most interesting results. Another alternative search
:20:35. > :20:37.tool is Blippex, which instead of ranking results with an algorithm no
:20:38. > :20:42.one understands, many because it is a closely guarded secret at Google,

:20:49. > :20:55.behaviour. One of the browsers that lingers on a page, the more interest
:20:56. > :20:58.that is deemed to be. That makes perfect sense to me. You can
