Theoretical presentation

Development principles

  • density: simultaneous multiplication, variable density of harmonic nature ;
  • development/deployment: successive multiplication;
  • memory: time delay (with variations in duration, timbre, screen, function).

Relationship between instrumental and non-instrumental scores

  • simple, immediate, direct transformation ;
  • recording ;
  • the synthetic score
  • virtual score.

Methods for triggering or stopping actions

  • pitch ;
  • duration ;
  • playing form ;
  • dynamics.

Harmonic extensions using delays

  • number of constant delays, and their density over time ;
  • variable number, constant density ;
  • constant number, variable density ;
  • variable number and density;
  • variability of start and end slopes.

Interference between figure rhythm and delay rhythm

  • regular figure rhythm, irregular delays ;
  • irregular figure rhythm, regular delays.

Changing intervals

  • by transposition
    • normal to a given interval
    • according to a modified scale
    • by mapping (bijective application)
  • by translation (with frequency shifting) with timbre modification.

Interval permutation

  • independently ;
  • according to musical execution.

Presentation of production methods

Description of electroacoustic device

  • transformation and tracking unit ;
  • sampling synthesis unit;
  • diffusion and spatialization device.

Description of the compositional plan

  • overall form (with the notion of return and memory) ;
  • data families ;
  • instrumental groups.

Description of the main characteristics of the "interstitial material"

  • random generators
    • simple random with repetition ;
    • random without value repetition ;
    • random with prohibition of a value for a time x ;
    • obligation to produce a value within a time x.
  • motivations for using sampling
    • real-time sound editing;
    • acoustic information, logical information.
  • technique for creating a synthetic flute
    • sample transposition constraints ;
    • nature of the instrument;
    • sample extension to infinity without looping.
