Sorry for the late reply 🙏 If you want all the chords starting from "D", this could work: import { ChordDictionary, Note, PcSet } from "tonal";
const notes = ["D3", "A3", "Bb3", "C4", "D4", "E4", "F4", "G4", "A4"];
const transposed = notes.map((note) => Note.transpose(note, "-2M"));
const set = PcSet.chroma(transposed); // => "101011010110"
const isSubset = PcSet.isSubsetOf(set);
const chordNames = ChordDictionary.all()
.filter((chord) => isSubset(chord.chroma))
.map((chord) => "D" + chord.aliases[0]);
console.log(chordNames);This will print: If you want all chords for all notes, maybe this: import { ChordDictionary, Interval, Note, PcSet, Scale } from "tonal";
const notes = ["D3", "A3", "Bb3", "C4", "D4", "E4", "F4", "G4", "A4"];
const uniqueNotes = Scale.scaleNotes(notes);
const chords = uniqueNotes.map((note) => {
const interval = Interval.distance("C", note);
const inverted = Interval.invert(interval);
const transposed = notes.map(Note.trBy(inverted));
const set = PcSet.chroma(transposed);
const isSubset = PcSet.isSubsetOf(set);
return ChordDictionary.all()
.filter((chord) => isSubset(chord.chroma))
.map((chord) => note + chord.aliases[0]);
});
console.log(chords);This will return a lot of chords: |

Danigb,
Thank you for replying. I will try out your suggestions to see if I am missing any chords, but in my playing around with your library I came up with the following to discover many chords that I can actually play on this subset of notes on the handpan:
var handpanNotes = ["D3", "A3", "Bb3", "C4", "D4", "E4", "F4", "G4", "A4"]; // Kurd
var scales = Tonal.Scale.detect(handpanNotes);
if (scales[0]) {
var scale = scales[0]; // first choice seems best
var chords = Tonal.Scale.scaleChords("chromatic") // get all possible chords
chords.forEach(function(chord) {
var chordName = Tonal.Chord.get(chord).name;
if (chordName === "") {
chordName = chord;
}
handpanNotes.forEach(function(handpanNote) {
var chordNotes = Tonal.Chord.getChord(chord, handpanNote).notes;
var isChordPossible = true;
chordNotes.forEach(function(chordNote) {
if (!handpanNotes.includes(chordNote)) {
isChordPossible = false;
}
});
if (isChordPossible) {
console.log(handpanNote + " " + chordName + " — " + chordNotes.join(', '));
}
});
});
}
This will give me the following results:
D3 fifth — D3, A3
A3 fifth — A3, E4
Bb3 fifth — Bb3, F4
C4 fifth — C4, G4
D4 fifth — D4, A4
A3 suspended fourth — A3, D4, E4
C4 suspended fourth — C4, F4, G4
D4 suspended fourth — D4, G4, A4
A3 suspended fourth seventh — A3, D4, E4, G4
Bb3 major — Bb3, D4, F4
C4 major — C4, E4, G4
Bb3 major seventh — Bb3, D4, F4, A4
Bb3 sixth — Bb3, D4, F4, G4
C4 sixth — C4, E4, G4, A4
A3 m7#5 — A3, C4, F4, G4
A3 minor — A3, C4, E4
D4 minor — D4, F4, A4
A3 minor seventh — A3, C4, E4, G4
A3 madd4 — A3, C4, D4, E4
D4 madd4 — D4, F4, G4, A4
Bb3 suspended second — Bb3, C4, F4
C4 suspended second — C4, D4, G4
D4 suspended second — D4, E4, A4
C4 sus24 — C4, D4, F4, G4
D4 sus24 — D4, E4, G4, A4
D3 eleventh — D3, A3, C4, E4, G4
If there is a better approach to using your library, or if I am missing something important please let me know. BTW, I have greatly enjoyed getting to work with your library!
Thanks!
Rick

Sorry for the late reply 🙏 If you want all the chords starting from "D", this could work:
import { ChordDictionary, Note, PcSet } from "tonal";
const notes = ["D3", "A3", "Bb3", "C4", "D4", "E4", "F4", "G4", "A4"];

.map((chord) => "D" + chord.aliases[0]);
console.log(chordNames);
This will print:
[

If you want all chords for all notes, maybe this:
import { ChordDictionary, Interval, Note, PcSet, Scale } from "tonal";
const notes = ["D3", "A3", "Bb3", "C4", "D4", "E4", "F4", "G4", "A4"];
const uniqueNotes = Scale.scaleNotes(notes);
const chords = uniqueNotes.map((note) => {
const interval = Interval.distance("C", note);
const inverted = Interval.invert(interval);
const transposed = notes.map(Note.trBy(inverted));
const set = PcSet.chroma(transposed);
const isSubset = PcSet.isSubsetOf(set);
return ChordDictionary.all()
.filter((chord) => isSubset(chord.chroma))
.map((chord) => note + chord.aliases[0]);
});
console.log(chords);
This will return a lot of chords:

Is it possible to query for a list of chords (triads, inversions, etc.) from a set of notes like the following:
"D3", "A3", "Bb3", "C4", "D4", "E4", "F4", "G4", "A4"
These are the notes on a typical Kurd handpan.
Scale.detect will correctly return 'D3 minor'. I can visually detect C Major and D Minor chords, but how can I programmatically locate these chords (and maybe more) using Tonal?
