TalkingTrees is a project by Bert Barten and a collaboration between artists, musicians, scientists and nature lovers.

This project lets the audience experience direct contact with nature through music.

The result is an interactive audiovisual performance. It consists of four tree sensors which are connected to a series of analogue synthesizers. The sensors provide information about the sap flow speed, foto synthesis, volatile organic compounds and moisture.

This information determines the pitch and timbre of the synthesizer sounds and also their spatial positioning.

The sound subsequently controls a couple of graphic image generators which are projected on big video screens.

The digital data of a tree which were collected during one year have been compressed in time and translated into musical values

One month became twenty minutes (as in a time lapse film).  The data of eight months (in winter this tree slept) resulted in eight musical pieces of the months april to november.

By this method of working the ego of the composer moves to the background. Now the source of the musical composition lies with the tree itself.

The Courage Company by Bert Barten

TalkingTrees presented their first CD and LP “Live” at the unique location of Radio Kootwijk. On sunday April 15 the large radio hall was filled with 400 spectators. After an introduction by host Petra Kalden guest speakers Harry Starren and Wim Hof elaborated on the theme ‘humans and nature’. Bert Barten continued with a discussion with the audience and responded to questions.

The evening was completed by an integral performance of the “Live” CD. The TalkingTrees line-up consisted of Hans Aalbers, Floris Kolvenbach, Dennis Verschoor and Dennis Sacerdos Vigilia on synthesizers, Hans Meijer visuals and Bert Barten music mixing.  

The CD&LP are available via the TalkingTrees OnlineStore. A TalkingTrees T-shirt has been added to the collection.

This year’s Dwarslopers Festival 2019 will be taking place in the city of Zeist at the Vrije Hogeschool Zeist and the Evangelische Broeder Gemeente.

TalkingTrees are closing the day around 21:30 in the Large Hall at the EBG with a performance by Hans Aalbers, Floris Kolvenbach, Jorgen Brinkman, Hans Meijer and Bert Barten. They will be monitoring one of the beautiful lime-trees in front of the hall.
