high level score?

• high level notation (e.g. trill is not just a series of notes)
• notation also includes performance practice (e.g. rambat damping, 古箏 pitch artifacts...)
• part of writing music is creating notation for that piece
• notation behaves correctly with regard to tempo and dynamics: a trill or grace notes or may not accelerate with the tempo, ornaments may be played differently at ff vs. pp.
• high level support for popular synthesizers and samplers including keyswitches etc.
