Enum Voicing 

pub enum Voicing {
    Close,
    Drop2,
    First,
    Second,
}

How the notes of a chord are spread out.

Every one of these preserves the chord’s pitch-class set — it is the same chord, arranged differently — which is the property the tests check.

Variants

Close

Drop2

The second voice from the top, down an octave. The definition is worth being precise about: it is not “the middle note”, and on a four-note chord it is the third note up, not the second.

First

Lowest voice up an octave.

Second

Lowest two voices up an octave.
