CA3: Update harmony selection principles

[rualark]

Currently harmony selection is affected by:

• Highest influence
  • Dissonance between chord tones
  • Not a single harmonic note on downbeat
  • 4th or tritone with bass
  • Unresolved non-harmonic suspension
• Low influence
  • 6/4 or 6th chord (lowest influence)

Could also include:

• When shape is triggered with a violation (e.g. leap before DNT). In this situation shape should trigger, but flag should be shown also:
  • Leap to/from DNT
  • Note 1 or 4 is too short / note 2 or 3 is too long
• Augmented harmony
• Wrong harmonic progression

New harmony selection rules (influence decrease order):

• No root note in chord - 1000
• Dissonance between chord tones - 100
• Unresolved non-harmonic suspension - 100
• 4th or tritone with bass - 100
• Not a single harmonic note on downbeat - 30
• 6/4 chord - 10
• Augmented chord - 3
• 6th chord - 1

Not included:

• Unresolved tritone - 0
• Wrong harmonic progression - 0
• When shape is triggered with a violation (e.g. leap before/after DNT/cam) - 0
