# 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. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
