What it does

The feature,
explained clearly

The Chords module in Earonman Practice Mode is a chord-quality drill. You pick which chord qualities to include, choose harmonic or melodic playback, restrict to specific inversions, and Earonman feeds you randomised exercises. No daily cooldown. Free Practice covers triads and 7th chords with inversions; PRO unlocks modal triads, extended chords, and altered colours within the same module.

01

Every triad quality

Major, minor, diminished, augmented. The four base qualities every musician must know cold.

02

All five 7th chord types

Major 7, dominant 7, minor 7, half-diminished, fully diminished. The five seventh chord qualities that cover almost all jazz and popular music harmony.

03

Modal triads (PRO)

Sus2, sus4, Phrygian, Lydian triads. The non-major/minor triad colours that appear in modal jazz, pop production, and film scoring - included in the PRO library.

04

Extended chords (PRO)

Add chords, 6 chords, 9ths, 11ths, 13ths, altered tensions. The harmonic colour vocabulary of modern jazz and R&B, unlocked with PRO inside the same Chords module.

05

Inversions as a separate skill

Identify whether the root, third, fifth, or seventh is in the bass. Critical for transcription and understanding what a pianist is voicing.

06

Harmonic vs melodic playback

Harmonic = all notes at once. Melodic = notes in sequence (arpeggiated). Earonman trains both because chord quality has to be recognisable regardless of how it is voiced in time.

07

Notation on the web

On the web, each chord is shown on a real notation staff alongside the audio - useful for connecting sound to the symbol you read in charts.

How it works

Three steps.
Repeated until it sticks.

01

Set up your session

Practice Mode > Chords. Tick which chord qualities to drill, pick harmonic or melodic playback, and choose whether to include inversions.

02

Hear the chord

A chord plays automatically. Tap Repeat to hear it again, or switch the playback mode between harmonic and melodic mid-session.

03

Tap your answer

Pick the chord quality (and inversion, if enabled) from the answer buttons. The notation and the correct answer reveal immediately so you can connect sound to symbol.

What you will learn

Skills you walk away with

Chord recognition is the second layer of relative pitch. Once intervals are solid, chord recognition is what lets you call out changes in real time, transcribe a tune by ear, and understand what a pianist is doing harmonically.

Tell apart the four triad qualities

Major, minor, diminished, augmented. Every harmonic decision in tonal music starts with these four colours.

Recognise all 7th chord types

The vocabulary that lets you transcribe jazz standards, pop ballads, R&B grooves, and almost everything else.

Identify the bass note

Root, 1st inversion, 2nd inversion, 3rd inversion (for 7ths). Hearing what the bass is doing changes how you interpret the entire harmony.

Hear modal triads in context (PRO)

Sus chords define modern pop. Phrygian triads anchor flamenco and modal jazz. Lydian triads colour film scores. Available in the PRO chord library inside Practice Mode.

Build a chord quality library

After enough reps, you stop thinking and just hear the chord. Major 7 has a specific colour. Half-diminished has a specific colour. The library becomes instinctive.

Prepare for voicings and extensions

Jazz voicings and extended harmony assume you already know what a basic chord type sounds like. This module is the prerequisite.

Why use it regularly

Daily reps.
Compound results.

Chord recognition decays even faster than interval recognition because the differences are subtler. Daily 5-10 minutes is the difference between hesitating on a m7b5 and naming it before the next chord lands.

Working musicians need instant recall

On the bandstand, in a session, in a producer chair - you do not have time to count chord tones. Daily drilling builds sub-second recognition.

Inversions matter in real music

Most musicians can hear root-position chords but choke on inversions. Inversions are everywhere in real music. Daily drilling closes this gap.

Harmonic and melodic are different skills

A chord played harmonically (all notes together) sounds different from the same chord played melodically (notes in sequence). Real music mixes both. Daily reps in both modes generalise the skill.

Modal triads are unfairly hard

Sus2, sus4, Phrygian, Lydian triads sound subtly different from major/minor. Daily reps are the only way to make these reliable.

Who is this for

Not just jazz musicians

Chord recognition is universal vocabulary. Every musician benefits from instant chord ID, regardless of style.

Jazz musicians

Call out changes by ear, transcribe solos, hear what the pianist is comping under a melody.

Pop and rock songwriters

Hear the difference between a maj7 and a 6 chord, recognise the m9 colour, write progressions intentionally instead of by trial-and-error.

Producers and beatmakers

Identify chord progressions in samples, hear which inversion fits the bass line, recognise modal triad colours in reference tracks.

Choir directors and arrangers

Vocal arrangements are about voice leading. Hearing chord qualities and inversions lets you write SATB by ear.

Classical musicians

Harmonic analysis in your head while sight reading. Faster transcription. Better intonation by understanding what chord the ensemble is on.

Songwriters at any level

You do not need to be advanced. The Chords module starts with just major and minor triads and builds up to 7ths and inversions.

Why Earonman

What makes this
different

Harmonic and melodic trained separately

Most apps only train chords played all at once. Earonman trains both harmonic (simultaneous) and melodic (arpeggiated) playback because real music mixes them.

Inversions as a dedicated skill

Most apps treat inversions as the same chord. Earonman trains bass-note identification as its own micro-skill.

Free 7th chords

7th chords are often paywalled in ear training apps. In Earonman Practice Mode, all five 7th chord types with inversions are free.

Full library with PRO

Modal triads (sus, Phrygian, Lydian), add chords, 6 chords, 9ths, 11ths, 13ths, altered colours - the same Chords module just expands with PRO. No new mode to learn.

The structured progression from basic intervals to complex jazz harmonies is brilliant. This is a game-changer for any serious musician.

Frequently asked

Your questions,
answered

What chord types are free in Practice Mode?
Free Practice covers the four triad qualities (major, minor, diminished, augmented) and all five 7th chord types (maj7, dom7, min7, half-diminished, fully diminished) with inversions. Modal triads (sus, Phrygian, Lydian), extended chords (9, 11, 13), and altered tensions unlock with PRO inside the same Chords module.
What is the difference between a half-diminished and a fully diminished 7?
Both are built from a diminished triad. Half-diminished adds a minor 7th on top. Fully diminished adds a diminished 7th, making the chord symmetric in minor 3rds. Practice Mode has both, and you can drill them side by side until the difference is instant.
Can I narrow down to a specific pair or small group of chord types?
Yes - and that is usually how you should drill. Ear training a single chord type in isolation has limited value: with only one option there is nothing to distinguish. The setup screen lets you pick exactly the pair or small group you want to compare - e.g. major 7 vs dominant 7, or all five 7th chord qualities together - so the differences you struggle with become the only differences you have to hear.
How long until I can recognise 7th chords reliably?
Most musicians get to reliable recognition of all five 7th chord types within 3-6 weeks of daily 10-minute sessions. Inversions add another month or so depending on your starting level.
Do I need to know music theory?
Basic note names help. You do not need to know what a "diminished triad" means in theory terms - the module teaches you the sound first, the name second.
