Key Concepts and Tech

  • Mapping is the process of connecting input data from sensors or controllers to musical parameters in the software
    • Effective mapping is crucial for creating intuitive and expressive interactive systems
    • Mapping strategies can be one-to-one, one-to-many, or many-to-many
  • Gesture recognition involves the use of sensors to capture and interpret physical movements as control input
    • Accelerometers, gyroscopes, and motion capture systems are commonly used for gesture recognition
  • Machine learning techniques, such as neural networks, can be employed to create adaptive and evolving interactive systems
  • Open Sound Control (OSC) is a protocol for communication between devices and software in interactive music systems
  • Max/MSP and Pure Data are popular visual programming environments for developing interactive music systems
    • These platforms provide a wide range of tools for audio processing, MIDI handling, and data manipulation
  • Sensors used in interactive music systems can include pressure sensors, proximity sensors, and biometric sensors (heart rate, EEG)

Historical Context

  • The development of interactive music systems can be traced back to the early 20th century with the advent of electronic musical instruments
  • In the 1960s, composers like John Cage and Karlheinz Stockhausen explored indeterminacy and live electronics in their works
    • Cage's "Variations V" (1965) incorporated dancers' movements to trigger sounds and manipulate audio
  • The rise of computer music in the 1970s and 1980s laid the foundation for more sophisticated interactive systems
    • Max Matthews' work at Bell Labs pioneered the use of computers for real-time audio synthesis and processing
  • The STEIM (Studio for Electro-Instrumental Music) in Amsterdam has been a key center for the development of interactive music technologies since its establishment in 1969
  • The advent of affordable personal computers and MIDI in the 1980s made interactive music systems more accessible to a wider range of artists
  • In recent decades, the proliferation of mobile devices, sensors, and open-source software has further democratized the field of interactive music

Notable Artists and Works

  • David Rokeby's "Very Nervous System" (1986-1990) used video cameras to track body movements and generate music in real-time
  • Laetitia Sonami's "Lady's Glove" (1991) is a sensor-equipped glove that allows the performer to control sound through hand gestures
  • Atau Tanaka's "BioMuse" (1992) utilized bioelectric signals from the performer's muscles to control digital audio processes
  • George E. Lewis' "Voyager" (1993) is an interactive improvisation system that listens to and responds to live performers
    • The system employs complex algorithms to analyze and generate musical material in real-time
  • Pamela Z's "BodySynth" performances feature wearable sensors that capture her physical movements and vocalizations to control live electronics
  • Imogen Heap's "Mi.Mu Gloves" (2010) are a pair of sensor-laden gloves that enable expressive control over music production and live performance

Hands-On: Building Your Own System

  • Start by identifying the desired musical interactions and control methods for your system
  • Choose appropriate sensors and controllers based on the intended interactions (accelerometers, pressure sensors, etc.)
  • Select a software environment for developing your interactive music system (Max/MSP, Pure Data, SuperCollider)
    • Consider factors such as ease of use, available libraries, and community support
  • Implement the mapping between input data and musical parameters in the software
    • Experiment with different mapping strategies to find the most expressive and intuitive connections
  • Incorporate audio processing and synthesis techniques to generate and manipulate sound in real-time
  • Test and refine your system through iterative design and user feedback
    • Engage performers and audiences to gather insights and improve the user experience
  • Document your process and share your work with the community to contribute to the collective knowledge in the field

Performance Techniques

  • Develop a deep understanding of the capabilities and limitations of your interactive music system
  • Practice performing with the system to build muscle memory and fluency in its use
    • Explore the range of expressive possibilities afforded by the system
  • Cultivate a sense of listening and responsiveness to the system's output
    • Engage in a dialogue with the system, allowing it to influence your musical decisions
  • Incorporate visual elements, such as projection mapping or light design, to enhance the audience's experience
  • Consider the staging and physical layout of the performance space to optimize the interactive elements
  • Embrace improvisation and spontaneity within the framework of the interactive system
    • Allow for moments of surprise and serendipity in the performance
  • Collaborate with other performers, both human and machine, to create rich and dynamic musical interactions
