## Four ways to write a chord

Set **Chord notation** in [Preferences](https://pianokitty.com/preferences).

- **American**: C, C#, Cm7
- **German**: C, Cis, H
- **Solfège**: Do, Ré, Mi
- **Jazz / Real Book**: C−7, CΔ7

German H is the note American calls B.

## Short or long names

**Chord-name form** is Short (Cm7) or Long (C minor 7).

Long names help while the symbols are new.

## Black keys and slash chords

**Black-key spelling** picks between C♯ and D♭: Sharps, Flats, Random or Auto (match scale).

Auto follows the key, so F major shows B♭, not A♯.

**Slash inversions (C/E)** put the bass note after a slash.

## Numerals and functions

In Scales and Progressions, **Question label style** can name a chord by its degree.

- Roman numeral: ii, V, vi
- Roman + quality: ii V vii° (Scales only)
- Arabic numeral: 2, 5, 6
- Function: tonic, dominant
