This section gathers general reflexions, rather than technical ones, on music, Jazz, improvisation as well as any strongly or weakly connected topic. Those articles were written on various occasions, which I will recall in their preamble.

• Lisp, Jazz, Aïkido
  
  This article is currently a first shot that I intend to make evolve towards a real essay.
• The (Natural) Language of Improvisation
  A vision of improvisation as a natural language, and the implications in terms of learning, pedagogy and teaching.
• What is a note ?
  Some ideas on the notion of (wrong) note and on the cognitive aspects of musical perception.
• Taming Harmony: an example
  Some ideas on how to tackle complex Jazz scores, on the harmonic but also rythmic plans. The general idea is that the coherency of an improvised discourse comes from the transitions between keys rather than the keys themselves.
