Pastry Cords (2019). Music is a universal language for all living beings. Despite the long music history of humanity, making music is limited to a few artists, and the way they listen is mostly similar. To overcome this, <Pastry Chords!> provides a creative and effortless way of enjoying music by incorporating artificial intelligence into the process of making and listening to music. It allows the participant -even without a knowledge of composition – to play with a number of melody pieces that were created by four chords presented to AI. By stacking them with various musical instruments, interesting music is produced covering various levels. Also, when listening to music, the melody connection point or the sound effect is changed according to the pose of the listener so that the music can be enjoyed in the form of active participation instead of the passive method.
