About Gestrument

We are making music interactive.

Gestrument was developed by contemporary classical composer Jesper Nordin as his own compositional tool in 2007. With this tool he has composed pieces for leading European ensembles and symphony orchestras.

After presenting the tool at Universities and Conservatories like Stanford (US), Berkley (US), Conservatoire de musique de Montréal (Can) and Conservatoire National Supérieur Musique et Danse de Lyon (Fr) he started to realize the full potential of what he had discovered and decided to develop this tool as an iOS app.

With the help of software designer Jonatan Liljedahl he then developed and released Gestrument for iOS in late 2012.

The original tool

In 2007 composer Jesper Nordin programmed the original tool in Max/MSP using a Wacom drawing board as input and was used by Nordin in many compositions. See a video from a session with the original tool at the musical centre GRAME in Lyon.

Several pieces by Jesper Nordin composed with this tool is found on the CD Pendants where cellist Benjamin Carat and ensemble Gageego! performs his music conducted by Pierre-André Valade.
