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

It is a project to let 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 synthesizers 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.

TalkingTrees will perform at the Caprera Music & Lights Festival in Bloemendaal/The Netherlands on Friday 8 and Saturday 9 September.

This open-air festival takes place in the woods surrounding Caprera’s open air stage. Visitors can follow various ‘color routes’ through the forest so the groups can stay small and intimate. Mobile bars and food-trucks are scattered over the area.

Bert Barten continued with a discussion with the audience and responded to questions.
