Enum Chord 

pub enum Chord {
    None,
    Fifth,
    Octave,
    Diatonic,
    Diatonic7,
    Maj,
    Min,
    Dim,
    Sus2,
    Sus4,
    Maj6,
    Min6,
    Dom7,
    Min7,
    Maj7,
    Quartal,
}

What a melodic step plays: one note, or several.

The order of this list is on disk — a step stores the chord it names by identity, so entries may be appended but never reordered. Diatonic and Diatonic7 take their quality from the degree the root sits on in the pattern’s mode, which is what makes a whole line of them sound like a key rather than like one chord transposed; every other entry is explicit, so that a borrowed chord stays borrowed.
