+## Ranges
+
+### `range.diatonic`
+
+```ts
+diatonic(start?: Interval, end?: Interval): Generator<Interval, void, unknown>;
+```
+
+Generates a range of `Interval` vectors between the two boundary `Interval`s passed-in, such that all intervals found diatonically occur.
+
+If no boundary `Interval`s are specified, defaults to P1 - P8.
+
+```ts
+let m = Interval.fromName("P1");
+let n = Interval.fromName("M9");
+Interval.range.diatonic(m, n).forEach(k => console.log(k.name));
+// P1 m2 M2 M3 P4 d5 A4 P5 m6 M6 m7 M7 P8 m9 M9
+```
+
+### `range.melodic`
+
+```ts
+melodic(): Generator<Interval, void, unknown>;
+```
+
+Generates all the intervals traditionally considered "easily singable". Essentially no dissonant leaps or augmented/diminished intervals, nor leaps bigger than an octave.
+
+```ts
+Interval.range.melodic().forEach(m => console.log(m.name));
+// P1 m2 M2 M3 P4 P5 m6 M6 P8

+```ts
+diatonic(from: Pitch, to: Pitch, context: TonalContext): Generator<Pitch, void, unknown>;

+
+```ts
+let context = TonalContext.fromStrings("C", "major");
+let p = SPN.toPitch("C4");

+
+```ts

+```
+
+Generates a chromatic range of `Pitch` vectors between the two boundary `Pitch`es passed-in, within the specified `TonalContext`. Essentially any all pitches between the boundaries that could occur diatonically or chromatically in a given tonal context.
+
+```ts
+let context = TonalContext.fromStrings("C", "major");
