CounterpointerReport

This library reports on a 1st species counterpoint and tells you which rules are violated. Its based on a 1:1 Counterpoint lecture by Jacob Gran

The cantus firmus is by Fancois-Josepf Fetis (1784-1871) The counterpoint is by Jacob Gran

CounterpointReport {
  isValidFirstSpeciesR = False,
  noDissonantIntervalsR = True,
  noLeapsInSameDirectionR = True,
  avoidParallelFourthsR = True,
  avoidParallelFifthsOrOctavesR = False,
  unisonOnlyBeginOrEndR = True,
  approachPerfectionR = True,
  beginAndEndPerfectlyR = True,
  mostlyContraryR = True,
  limitIntervalR = True,
  lessThan3RepeatedIntervalsR = True,
  mostlyStepsCantusFirmusR = True,
  mostlyStepsCounterpointR = True,
  onlyConsonantLeapsR = True
}

This library uses Euterpea to render the MIDI output, and modular-arithmetic to calculate the intervals.

Building

If you're trying to get this to build locally, you'll probably want to use my patched versions of Euterpea and PortMIDI-Haskell

Hopefully we can get those fixed up.
