# Numerals

> To find this setting, [**navigate to the "Musical preferences"**](/settings/musical-preferences/untitled.md)**.**

### ▶️ Numerals type

You can either display roman numerals (`I ii V vi` etc.) or the Nashville numbers (`1, 2, 3` etc.). \
They are basically the same, only the type of writing differs.

### ▶️ Numerals relation

You can also adjust the relation of the numerals. 

When you have selected **"Relative to root note of mode"** (Default), the root of the mode will always be the "one". 

> For example, if you change the mode from major (Ionian) to minor (Aeolian) in the key if "C", the "C" will change from the degree `I` degree  `vi` .

When you have selected **"Relative to Ionian mode",** the root will always be the Ionian relative.

> For example, if you change the mode from major (Ionian) to minor (Aeolian) in the key if "C", the "C" will be the degree `I` even after changing to minor.

{% hint style="info" %}
If a roman numeral is written in **uppercase** letters, it represents a **major** chord. 

If it is written in **lowercase**, it represents a **minor** chord. 

If it has a **little circle** next to it and is written in **lowercase**, it represents a **diminished** chord.
