This lesson is part of the Fundamentals of Sound & Music module.


  • Student will be able to notate and interpret/define various articulation symbols.
  • Students will be familiar with ADSR sound envelopes and their components.
  • Student will be able to relate different aspects of the attack envelope with perceived articulation and/or dynamic.
  • Student will understand the relationship between pitch, loudness, and timbre.
  • Student will be able to derive the harmonics for specific wave shapes given a fundamental frequency (triangle, sawtooth, square).




Class Activities[edit]

  • Discussion and definition of ADSR envelope with demo.
  • Illustration of articulation with different instruments, comparison of oscilloscope/spectrogram with ADSR envelope graph.
  • Alteration of harmonics for various wave shapes (demo).
  • Visualization of timbre changes on spectrogram/oscilloscope.
