guitar-chord_skill

Overview

This skill is a compact guitar chord toolkit that identifies chords from notes, provides chord diagrams and inversions, shows scale notes and diagrams, and includes a capo transposition calculator. It works with common chord types and scale families and accepts sharps, flats, and natural note names in a case-insensitive format.

How this skill works

Enter a chord name to get its constituent notes and an optional fretboard diagram. Provide a set of notes to perform reverse lookup and find matching chord names. Request inversions to see each voicing’s pitch order, request scales to list scale tones and diagrams, and use the capo calculator to map open-chord shapes to actual pitch when a capo is applied.

When to use it

• You need to identify a chord from a set of played notes (reverse lookup).
• You want clear note lists and fretboard diagrams for a named chord.
• You need all inversions of a chord to arrange voicings.
• You want scale tones and diagrams for improvisation or composition.
• You need to transpose chord shapes with a capo quickly.

Best practices

• Provide note names in standard formats (C, C#, Db) and be consistent with enharmonic spelling when comparing results.
• Use the diagram option when preparing arrangements to visualize fingerings.
• For reverse lookup, include as many sounding notes as possible to reduce ambiguous matches.
• Check inversion output when arranging for specific bass movement or voicing.
• Use the capo calculator with the target fret number to confirm actual concert pitch.

Example use cases

• Identify an unknown chord from a recorded riff by supplying the played notes for reverse lookup.
• Generate chord diagrams and note lists for charting songs or teaching students.
• List all inversions of C7 to craft bass lines or voice-leading transitions.
• Look up C major scale tones and a diagram before soloing over a progression.
• Calculate how an open G shape sounds when a capo is placed at the 2nd fret.
