Optionalalternatives?: booleanReport the readings this analysis turned down: the function the chord's degree alone would have carried, the tonicizing reading a dominant sonority could have had, and the numerals the other rendering options would emit.
Off by default. The rationale is built from facts the analysis already established, but a rival costs work nothing else needs — a second and third numeral rendering among them — and most callers read the conclusion only.
Options for analyzeChord: ChordToRomanOptions plus the switch for the rival readings.
