theory
of
motion

Established by Alexander Sonnenfeld in 1999 for turntablism and evolved to encompass all forms of controllerism, providing a theoretical and methodological framework for creating a notation system for digital live performance.

Theory of motion 2.0

Since 2018, Alexander Sonnenfeld has been working on the updating of Theory of Motion, which will be published step by step by the end of 2023. In this theoretical framework, he analyzes modern forms of digital live performance based on Snotation, and also refer to new technological aspects to advance playing techniques on the controller instrument. Please check the various topics that will be covered in this book.

Scratching

To create sounds by hand through the rhythmic coordination between fader and record movement.

Beat Juggling

To create new pattern by rearranging two different or identical drum sequences by hand.

Finger Drumming

To create complex beats by triggering audio samples or sounds on a MIDI pad controller.

Loop Playing

To create musical sequences by moving small loops forward or backward + changing the length.

Synctablism

To extend the acoustical and technical possibilities of DJ performance by incorporating the sync button.

Visualism

To transfer the concept of Theory of Motion to visual controllerism based on scratch techniques.

Designed for disks, faders, knobs, sensors and buttons
