Train Intervals & Chords
Practice in Any Key
Ear training is the practice of learning to recognize what you're hearing: the interval between two notes, the quality of a chord, the function of a progression. It's the difference between "that sounds nice" and "that's a ii-V-I in F."
For most musicians, the gap between reading music and hearing music stays wider than it should. You learn your scales, you learn your chord shapes, you practice pieces — but when you hear a song you love, can you tell what chord is playing? When a bass player hits a note, can you name it? Ear training closes that gap.
Traditional ear training drops you into rapid-fire drills: hear an interval, name it, hear another, name it, keep going. No context. No theory first. No visual reinforcement. If you get it right, the app moves on. If you get it wrong, you try again. This is how most ear training apps work, and it's why most people quit after a week.
Ear Trainer Master was built differently. Every lesson starts with a concept intro — a short, interactive screen that shows you what the interval or chord looks like on a piano keyboard and a guitar fretboard, then lets you hear it in context with song anchors you already know. Only then does the quiz begin.
The app covers six content domains, building on top of each other in a prerequisite structure:
You can take them in order (Tutor Mode — unlocks after 80% mastery) or jump around freely (Free Mode).
Most ear trainers pick a side: either they show you a piano keyboard, or a generic note label. Ear Trainer Master shows both a piano keyboard and a real guitar fretboard with proper voicings. See the same interval as a piano shape and a fretboard shape. Switch voicing styles — open, barre, rootless — to match what you actually play. It's the app we wish existed when we were learning.
The tonal center selector lets you pick which key to train in, so you can target the keys you actually play in. You can also let the app pick a random tonic each quiz, or enable moving tonic mode for a higher-difficulty drill.

Ear training for guitarists is different from piano-based ear training. Here are the five exercises every guitarist should drill, a 30-day plan, and the best tools for fretboard-based training.
Learn how to hear and identify chord progressions by ear — I-IV-V, I-V-vi-IV, ii-V-I, and more. A practical method for training your ear to recognize progression shapes in any key.
Learn how to identify every interval by ear using the song anchor method, from minor seconds to octaves. A practical guide with drills, tables, and a 30-day plan.
Relative pitch and perfect pitch are often confused but are completely different skills. Here's what each one actually means, which can be trained, and what matters for musicians.
Ear training is the practice of recognizing musical elements by sound. This guide explains what it is, why it matters, and how to start training your ear effectively.
Ear training is the practice of recognizing musical elements by sound — intervals, chords, progressions, rhythms. It's how musicians learn to identify what they're hearing and transcribe music without looking at a score.
No. The app uses audio, visual piano keyboards, and guitar fretboards throughout. You don't need to read sheet music to complete any lesson.
Both work. Ear Trainer Master shows a piano keyboard and a guitar fretboard side by side on every quiz, so you can train with the instrument you play. Most serious ear trainers get comfortable with both eventually.
Most users report noticing a real difference in interval recognition within 2-3 weeks of daily 10-minute practice. Chord recognition takes longer — typically 6-8 weeks to feel confident on triads and sevenths.
Yes. After the first download, all lessons, audio, and quizzes work without an internet connection.

Relative pitch is the ability to identify notes and intervals in relation to a reference pitch — it's a trainable skill, and it's what Ear Trainer Master teaches. Perfect pitch is the ability to identify any note without a reference, and it's generally considered not trainable past early childhood.
Guitarists, pianists, singers, songwriters, and music students who want to identify intervals, chords, and progressions by ear. The app is designed for beginners through intermediate learners — jazz students will find the extended-chord and secondary-dominant lessons particularly useful.
