tonal

6.3.0

  • New Key.majorKeyChords and Key.minorKeyChords functions.
import * as Key from "tonal";

Key.majorKeyChords("C").find((chord) => chord.name === "Em"); // => { name: "Em", roles: ["T", "ii/II"] }
  • Renamed fields of key results. secondaryDominantsMinorRelative is now secondaryDominantSupertonics and substituteDominantsMinorRelative is now substituteDominantSupertonics. Previous names are kept for compatibility as deprecated (will be removed in next major version)

6.2.0

Minor Changes

default export is deprecated for @tonaljs modules

Using default exports for single packages are deprecated, so instead of:

import Note from "@tonaljs/note";

You should do this:

import * as Note from "@tonaljs/note";

The same for all modules.

Patch Changes

Fix: add Note.distance back

The documentation said Note.distance was available, but was not.

Now you can do:

import { Note } from "tonal";
Note.distance("c4", "e7"); // => "24M"

Fix a bug finding distance between notes when they are in adjacent octaves (see #428)

6.1.0

New rhythm-pattern package:

import { RhythmPattern } from "tonal";

RhythmPattern.euclid(8, 3); // => [1, 0, 0, 1, 0, 0, 1, 0]
RhythmPattern.binary(12, 13); // => [1, 1, 0, 0, 1, 1, 0, 1]
RhythmPattern.hex("8f"); // => [1, 0, 0, 0, 1, 1, 1, 1]
RhythmPattern.onsets(1, 2, 2, 1); // => [1, 0, 1, 0, 0, 1, 0, 0, 1, 0]
RhythmPattern.random(4); // => [1, 0, 0, 1]
RhythmPattern.probability([0.6, 0, 0.2, 0.5]); // => [0, 0, 0, 1]
RhythmPattern.rotate([1, 0, 0, 1], 2); // => [0, 1, 1, 0]

6.0.1

Scale.get ignores case.

Now both calls returns the same scale:

Scale.get("C Major");
Scale.get("c major");

6.0.0

Major Changes

#### Breaking change: chord uses pitch classes, never notes with octaves

Chords now uses only pitch classes. Before Chord.getChord('M', 'C4') would consider C4 to be the tonic and now is `C``

So before:

Chord.get("M", "C4"); // =>
// {
//   name: 'C4 major',
//   tonic: 'C4',
//   notes: [ 'C4', 'E4', 'G4' ]
// ...
// }

Now:

Chord.get("M", "C4"); // =>
// {
//   name: 'C major',
//   tonic: 'C',
//   notes: [ 'C', 'E', 'G' ]
// }

Feature: slash chords

  • Chord now accepts a slash and a bass. The bass must be a pitch class
  • Chord properties include bass that is a pitch class that could or could not belong to the chord itself.

Example:

Chord.get("Cmaj7/B");
Chord.get("Eb/D");

Feature: chord notes

Now notes property of a chord are always pitch classes, there's a new function to get the actual notes:

Chord.notes("Cmaj7", "C4"); // => ['C4', 'E4', 'G4', 'B4']
Chord.notes("maj7", "D5"); // => ['D5', 'F#5', 'A5', 'C#6']
  • 48fecc4: Fix typo (breaking change): substract is now subtract
  • 48fecc4: Breaking change: remove NoInterval interface. Return Interval type (with emtpy: true) when parsing invalid intervals.
  • 48fecc4: Breaking change: NoNote interface is removed. Always return Note type (with empty: true) when parsing invalid notes.

5.0.1

  • Add -maj7 chord alias
  • Updated dependencies
    • @tonaljs/chord-type@5.0.2

5.0.0

Major Changes

Breaking change: Chord.get and Chord.tokenize assumes all numbers are part of the chord type, and never the tonic octave, when using with a single string parameter.

Before, in v4.x:

Chord.get("C4maj7"); // => { symbol: 'Cmaj7', tonic: 'C4' ... }

Now, in > 5.x:

Chord.get("C4maj7"); // => { empty: true } <- there is no "4maj7" chord type, so no chord is returned

The old behaviour can be replicated by using an array as parameter.

This works both in v4.x and v5.x:

Chord.get(["C4", "maj7"]); // => { symbol: 'Cmaj7', tonic: 'C4' ... }

The reasons for this change are:

  1. Chord symbols never use octaves
  2. The old behavior is confusing and arbitrary

Adopt a fixed/locked mode with lerna. Before, each module has it's own version. Now the same version is used for all modules. More info

Deprecated modules:

  • @tonaljs/modules (use tonal)
  • @tonaljs/array (use @tonaljs/collection)

Before

Before 4.5.0 there's no changelog, sorry 🙏. I'm afraid you have to dive into commits.

To make things worse, each module had it's own version, making difficult to know what was released when.

At least I'll try to keep this one up to date

Theres a migration guide for older versions (pre 4)
