How Music Theory and Ear Training Are Really the Same Thing
Music theory and ear training are best learned together: ear training is your instinct for recognising what you hear, music theory is the prepared knowledge that explains it, and transcription is the practice that joins the two.
Key points
- Ear training is instinct; music theory is the preparation that explains what you hear.
- Chords with the same quality, like G, C and D major in G, are told apart by function, such as V pulling to I.
- Notation can be used to play, sight sing, read rhythm and, most importantly, transcribe.
- Transcription sharpens both theory and ear training and builds confident playing.
- Treat theory as music history, and use maths and physics to explore rhythm, harmony and timbre.
What this lesson covers
In this talk, Jason Zac of Nathaniel School of Music explains why music theory and ear training should never be studied separately. It is aimed at any musician, from beginner to experienced, who has wondered whether theory is worth learning when apps and slowed-down videos can show you the chords. He also covers how to use staff notation, why transcription is underrated, and how to build a healthier mindset towards learning.
Instinct, technique and preparation
Jason uses a simple picture. Imagine walking into the wilderness when a leopard is about to attack:
- Ear training is the instinct – sensing that the danger is there, or in music, recognising that a particular chord or sound has arrived.
- Instrument technique is your physical fitness – the ability to actually act on what you heard.
- Music theory is the backpack – the tools and preparation you carry, which let you explain and respond to what you just heard.
Without theory, what you hear stays as clutter. He compares the mind to a librarian who only shelves information that is properly labelled. Theory gives your ears a template, so sounds get filed neatly instead of being ignored.
An example: chords of the major scale
Build triads in thirds on each note of a major scale and you get seven chords: I, IV and V are major, ii, iii and vi are minor, and vii is diminished. In G major, the I, IV and V chords are G B D, C E G and D F# A. All three are major, so they share the same sound quality.
To tell them apart you need function, not just colour. The D major chord does not feel stable in G major; it pulls towards G. That is the dominant resolving to the tonic. Jason stresses that studying this on paper is pointless unless you can hear the V chord acting like a magnet that wants to lock onto home. Equally, your ears improve once theory tells you what to listen for.
The same goes for scales and modes. Once you know the modes of the major scale (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian) and the melodic and harmonic minor scales, your ears still need to find them in real songs. The major scale is just one scale among many; Carnatic music alone has 72 melakarta ragas.
Ways to use notation
- Read and play on your main instrument, in whatever clef it uses.
- Sight singing – read and sing. This builds your voice, your interval knowledge and a real-world sense of pitch and rhythm.
- Rhythm reading – clap rhythms from a rhythm book, then turn them into a melody, an arpeggio pattern or a bass line.
- Transcription – the most important use. Listen and write down what you hear.
Why transcription matters
You can transcribe any single part: a triangle in an orchestra, the kick drum, the piano left hand, a flute melody or the vocal line of a bridge. You can capture harmony, melody and rhythm. Transcription keeps both theory and ear training honest, and once it is written down you can play it with confidence because the music is truly yours, rather than copied finger by finger like a parrot.
Building the right mindset
- Think of music theory as music history: the study of what great artists past and present actually did. Find out who your favourite musicians admired and listen to them too.
- Do not limit yourself to one tradition; absorb what you can from any culture.
- Use maths and physics. If a beat is divided into three, each slot is either played or silent, giving two to the power of three, or eight rhythm possibilities, which you can work out yourself instead of relying on a book.
- Study sound and timbre, such as why a violin and a flute playing the same middle C sound different.
How to practise
Whenever you learn a theory idea, go and hear it in songs. Whenever you hear something you like, try to name it and write it down. Add regular sight singing, rhythm clapping and short transcriptions to your routine so ear and theory grow together.
Questions about this lesson
Why should I learn music theory and ear training together?
Ear training gives you the instinct to recognise a sound, and theory gives you the knowledge to explain and use it. Your ears improve when theory tells you what to listen for, and theory sticks when you can actually hear it.
How can I hear chord function, not just chord quality?
Compare chords with the same quality in one key, such as G, C and D major in G major. Notice that the D chord feels unstable and pulls back to G; that pull is the dominant resolving to the tonic.
What is music transcription?
Transcription means listening to music and writing it down. You can transcribe any single part, such as a bass line, a drum part or a vocal melody, capturing its harmony, melody or rhythm.
How does maths help with rhythm?
If you divide a beat into three slots and each slot is either played or silent, you get two to the power of three, which is eight possible rhythms. Working this out yourself gives you more options than a fixed list in a book.
