MusicLab Copenhagen

After nearly three years of planning, we can finally welcome people to MusicLab Copenhagen. This is a unique “science concert” involving the Danish String Quartet, one of the world’s leading classical ensembles. Tonight, they will perform pieces by Bach, Beethoven, Schnittke and folk music in a normal concert setting at Musikhuset in Copenhagen. However, the concert is nothing but normal.

Live music research

During the concert, about twenty researchers from RITMO and partner institutions will conduct investigations and experiments informed by phenomenology, music psychology, complex systems analysis, and music technology. The aim is to answer some big research questions, like:

  • What is musical complexity?
  • What is the relation between musical absorption and empathy?
  • Is there such a thing as a shared zone of absorption, and is it measurable?
  • How can musical texture be rendered visually?

The concert will be live-streamed (on YouTube and Facebook) and it will also be aired on Danish radio. There will also be a short film documenting the whole process.

Real-world Open Research

This concert will be the biggest and most complex MusicLab event to date. Still, all the normal “ingredients” of a MusicLab will be in place. The core is a spectacular performance. We will capture a lot of data using state-of-the-art technologies, but in a way that is as little obtrusive as possible for performers and the audience. After the concert, both performers and researchers will talk about the experience.

Of course, being a flagship Open Research project, all the collected data will be shared openly. The researchers will show glimpses of data processing procedures as part of the “data jockeying” at the end of the event. However, it is first when all data is properly uploaded and pre-processed that data processing can start. All the involved researchers will dig into their respective data. But since everything is openly available, anyone can go in and work on the data as they wish.

Proper preparation

Due to the corona situation, the event has been postponed several times. That has been unfortunate and stressful for everyone involved. On the positive side, it has also meant that we have been able to rehearse and prepare very well. Already a year ago we ran a full rehearsal of the technical setup of the concert. We even live-streamed the whole preparation event, in the spirit of “slow TV”:

I am quite confident that things will run smooth during the concert. Of course, there are always obstacles. For example, one of our eye-trackers broke in one of the last tests. And it is always exciting to wait for Apple and Google to approve updates of our MusicLab app in their respective app stores.

MusicTestLab as a Testbed of Open Research

Many people talk about “opening” the research process these days. Due to initiatives like Plan S, much has happened when it comes to Open Access to research publications. There are also things happening when it comes to sharing data openly (or at least FAIR). Unfortunately, there is currently more talking about Open Research than doing. At RITMO, we are actively exploring different strategies for opening our research. The most extreme case is that of MusicLab. In this blog post, I will reflect on yesterday’s MusicTestLab – Slow TV.

About MusicLab

MusicLab is an innovation project by RITMO and the University Library. The aim is to explore new methods for conducting research, research communication and education. The project is organized around events: a concert in a public venue, which is also the object of study. The events also contain an edutainment element through panel discussions with world-leading researchers and artists, as well as “data jockeying” in the form of live data analysis of recorded data.

We have carried out 5 full MusicLab events so far and a couple of in-between cases. Now we are preparing for a huge event in Copenhagen with the Danish String Quartet. The concert has already been postponed once due to corona, but we hope to make it happen in May next year.

The wildest data collection ever

As part of the preparation for MusicLab Copenhagen, we decided to run a MusicTestLab to see if it is at all possible to carry out the type of data collection that we would like to do. Usually, we work in the fourMs Lab, a custom-built facility with state-of-the-art equipment. This is great for many things, but the goal of MusicLab is to do data collection in the “wild”, which would typically mean a concert venue.

For MusicTestLab, we decided to run the event on the stage in the foyer of the Science Library at UiO, which is a real-world venue that gives us plenty of challenges to work with. We decided to bring a full “package” of equipment, including:

  • infrared motion capture (Optitrack)
  • eye trackers (Pupil Labs)
  • physiological sensors (EMG from Delsys)
  • audio (binaural and ambisonics)
  • video (180° GoPros and 360° Garmin)

We are used to working with all of these systems separately in the lab, but it is more challenging when combining them in an out-of-lab setting, and with time pressure on setting everything up in a fairly short amount of time.

Streaming live – Slow TV

In addition to actually doing the data collection in a public venue, where people passing by can see what is going on, we decided to also stream the entire setup online. This may seem strange, but we have found that many people are actually interested in what we are doing. Many people also ask about how we do things, and this was a good opportunity to show people the behind-the-scenes of a very complex data collection process. The recording of the stream is available online:

To make it a little more watcher-friendly, the stream features live commentary by myself and Solveig Sørbø from the library. We talk about what is going on and make interviews with the researchers and musicians. As can be seen from the stream, it was a quite hectic event, which was further complicated by corona restrictions. We were about an hour late for the first performance, but we managed to complete the whole recording session within the allocated time frame.

The performances

The point of the MusicLab events is to study live music, and this was also the focal point of the MusicTestLab, featuring the very nice, young student-led Borealis String Quartet. They performed two movements of Haydn’s Op. 76, no. 4 «Sunrise» quartet. The first performance can be seen here (with a close-up of the motion capture markers):

Then after the first performance, the musicians took off the sensors and glasses, had a short break, and then put everything back on again. The point of this was for the researchers to get more experience with putting everything on properly. From a data collection point of view, it is also interesting to see how reliable the data are between different recordings. The second performance can be seen here, now with a projection of the gaze from the violist’s eye-tracking glasses:

A successful learning experience

The most important conclusion of the day was that it is, indeed, possible to carry out such a large and complex data collection in an out-of-lab setting. It took an hour longer than expected to set everything up, but it also took an hour less to take everything down. This is valuable information for later. We also learned a lot about what types of clamps, brackets, cables, etc., that are needed for such events. Also useful is the experience of calibrating all the equipment in a new and uncontrolled environment. All in all, the experience will help us in making better data collections in the future.

Sharing with the world

Why is it interesting to share all of this with the world? RITMO is a Norwegian Centre of Excellence, which means that we get a substantial amount of funding for doing cutting-edge research. We are also in a unique position to have a very interdisciplinary team of researchers, with broad methodological expertise. With the trust we have received from UiO and our many funding agencies, we, therefore, feel an obligation to share as much as possible of our knowledge and expertise with the world. Of course, we present our findings at the major conferences and publish our final results in leading journals. But we also believe that sharing the way we work can help others.

Sharing our internal research process with the world is also a way of improving our own way of working. Having to explain what you do to others help to sharpen your own thinking. I believe that this will again lead to better research. We cannot run MusicTestLabs every day. Today all the researchers will copy all the files that we recorded yesterday and start on the laborious post-processing of all the material. Then we can start on the analysis, which may eventually lead to a publication in a year (or two or three) from now. If we do end up with a publication (or more) based on this material, everyone will be able to see how it was collected and be able to follow the data processing through all its chains. That is our approach to doing research that is verifiable by our peers. And, if it turns out that we messed something up, and that the data cannot be used for anything, we have still learned a lot through the process. In fact, we even have a recording of the whole data collection process so that we can go back and see what happened.

Other researchers need to come up with their approaches to opening their research. MusicLab is our testbed. As can be seen from the video, it is hectic. Most importantly, though, is that it is fun!
