10

• Application of MaMuTh
• music theory for composition - modulation
  theory ( from known analyses) - classification
  of motives ( from known analyses
  Schuberts setting of Stolbergs poem Lied
  zu singen auf dem Wasser, für meine Agnes)
• Syntagmatic composition methods - Boolean
  operations on sets of notes - Local-global
  structures (manifolds)
• paradigmatic methods - transformations of
  single note sets - grids of motives -
  deformation (morphing, alteration, quantization)
• Performance theory of tempo curve hierarchies
