Repertoire Plugin

A plugin for Obsidian that renders chord charts written in Nashville-style Arabic numeral notation (e.g. 1, 4, 5/7).

Chord parsing and transposition are powered by degree-chords.

Features

• Write charts using Arabic numerals (1, 2, 5/7) instead of letter chords
• Set the key (and optional capo) in note frontmatter
• Major and minor keys (C, G, Am, F# minor, etc.)
• Altered chords (b3, #4, b7)
• Slash chords (1/3, 5/7)
• Extended qualities (4maj7, 57, 5sus4, 1add9)

Showing Chords

Use a repertoire code block:

1 5 6 4

In the key of C, this renders as:

C G Am F

Parentheses

Wrap a chord in parentheses for optional or passing chords. The parentheses are preserved in the output.

1 (5/7) 6 4

In the key of C:

C (G/B) Am F

Section markers

Lines with section labels in square brackets are styled as headings:

[Verse]
1 4 5 1

Key and Capo

Set the sounding key and capo fret in frontmatter:

---
Key: C
Capo: 3
---

The header above each block shows the frontmatter values (Key: C | Capo: 3). Chords inside the block are transposed to the fingered shapes you play with a capo — shapes are shifted down by the capo fret count so the sounding pitch matches the key.

With Key: C and Capo: 3, 1 2 renders as A Bm (not C Dm).

Capo must be an integer from 0 to 11. Invalid keys or capo values show an error in the block.

Minor keys

Use compact or spelled minor keys in frontmatter:

---
Key: Am
---

or

---
Key: G minor
---

Diatonic defaults follow the natural minor scale unless a quality suffix overrides them (e.g. 2dim, 4maj7).

Tip: Displaying a whole setlist on a single page

Keep each song in its own note, then embed them in a setlist note with ![[note name]].
