• Percussion-Resonance

  • What is an instrument or a Sound Body?
    • Exciter
    • Resonator
    • Diffuser
  • With Instruments, we can refer to excitation - attack and its consequence
    • ADSR

      • Attack
      • Decay
      • Sustain
      • Release

  • Percussion

    • Typically, with percussion sounds, it's common for people to pay more attention to the gesture that created the sound or the rhythm which is sounding, which hides the energy. We should look beyond the gesture and rhythm to the "perspective of the resulting sound."
    • Person/Pierre Schaeffer/Make Hear pair is a concept that making and hearing are kind of bound up and entangled together
    • It's important to consider Microphones as well as any Sound/Speakers and how they are set up together.
      • Microphone movement can be a musical gesture
      • Microphone manipulation can be part of Percussion

  • Resonance

    • Resonance is the result of Percussion, its Harmonic Halo
    • The Attack is given color by its resulting Resonance
      • Changing the shape of the Resonator can change the resulting Harmonics
    • If you use gestures to play with a Mic, you can shape Resonance
      • Person/Ben Burtt swung a mic around, "The pitch changes of lightsaber movement were produced by playing the basic lightsaber tone on a loudspeaker and recording it on a moving microphone, generating Doppler shift to mimic a moving sound source" -- wikipedia
    • Contact Microphones make the sound appear flattened, without a third dimension
    • By using different types of Exciters (e.g. striking materials) on the same Sound Body, one can change the Attack and Resonance as well as different "phenomena provoked by" them

  • Instrument Examples

    • Instrument/Trumpet has a hard attack and a sustained resonance
    • Piano has a hard attack and an immediate decay resonance, without sustain, whose decay one does not control, except through the use of the pedal
    • Violin has a soft attack, and a controlled sustain, without decay, except that defined by the acoustics of the space
    • Dry Percussion has a brief Attack, of strong Amplitude, without Sustain, with rapid Decay
    • The Dynamic factor (amplitude / loudness) and Harmonic Halo are part of the attack and sustain
