Understanding the FET Learning Materials

Different ways to explore musical notes, their functions, and their relationships within a tonal context.

Functional Ear Training is about developing a sense of how notes behave within a key or a harmonic context. Rather than focusing exclusively on recognizing isolated intervals, you learn to hear individual notes in relation to a tonal center.

And the best way to explore these relationships is to make music yourself: listen, sing, play, experiment, and discover how the notes sound and feel.

FunctionalEarTraining.com offers several types of learning materials for this purpose. Some provide you with musical phrases to imitate. Others create a harmonic background against which you can explore notes and their functions on your own.

The materials serve different purposes, but they share a common idea: Learning to recognize musical relationships through active listening and making music.

1. Call-and-Response Tracks – Listen, Recognize, Respond

The Call-and-Response Tracks are the most structured exercises in the FET collection.

The principle is simple: You hear a short sequence of notes — the call — followed by a space for your own response.

Your task is to reproduce what you have heard, either by singing or playing your instrument.

The important part is not merely reproducing the pitches. It is becoming familiar with the musical function of each note: how it relates to the tonic, the underlying harmony, and the other notes in the exercise.

Three ways to hear the same exercise

The Call-and-Response collections provide three versions of each exercise:

  • Instrumental Calls: The notes are played by an instrument. You listen and reproduce them, identifying the scale degrees yourself if you wish.
  • Nashville Numbers: A singer performs the notes using their scale-degree numbers — One, Two, Three, and so on.
  • Movable-Do Solfège: A singer performs the same notes using syllables such as Do, Re, and Mi.

These versions allow you to approach the same musical material in different ways.

The sung versions make the scale-degree names audible. The instrumental version lets you test whether you recognize the functions without hearing their names first.

Each collection includes exercises in all twelve keys, with the same functional note sequences.

Different collections, different musical challenges

Not every Call-and-Response collection uses the same selection of notes.

Some exercises are deliberately limited to just three scale degrees. Others introduce a larger selection, eventually covering all seven degrees of the major scale.

For example, a collection using only degrees 1, 2, and 3 lets you concentrate on the distinct character of Do, Re, and Mi within a stable tonal context.

A collection using degrees 1 through 7 introduces a considerably wider range of relationships.

The harmonic background also matters. Hearing a note against a major seventh chord is not quite the same experience as hearing it against another chord type.

By changing the available notes or the harmonic setting, the different collections provide opportunities to explore specific aspects of functional hearing.

Use these tracks when you want a structured exercise that gives you something to listen to, recognize, and reproduce.

2. Backing Tracks – Explore Notes Against a Harmonic Background

Call-and-Response Tracks give you specific notes to reproduce. Backing Tracks work differently.

They provide the harmonic setting, but leave the actual musical activity to you.

For example, the FET collection includes backing tracks built around a single major seventh chord and tracks featuring diatonic minor chords.

A single-chord backing track may seem simple, but there is plenty to explore.

Play or sing the root, third, fifth, and seventh of the chord. Then explore notes that do not belong to the chord itself.

Notice how differently these notes relate to the harmony.

Some sound stable or settled. Others introduce tension, color, or an expectation of movement.

You can also experiment with short melodies, melodic patterns, or improvisation.

Why practice with just one chord?

In a piece of music, the harmony may change every few beats. This creates a constantly changing musical context.

Practicing over a single chord removes that additional complexity.

The harmonic reference stays constant, allowing you to concentrate on the relationship between individual notes and the underlying chord.

For example, over a Cmaj7 chord, you might explore the notes C, D, and E.

C is the root of the chord, E is its major third, and D is the ninth — a note outside the basic four-note chord but still part of the broader harmonic sound.

Listening to these differences while singing or playing them is a practical way to become familiar with their characteristics.

Use Backing Tracks when you want to experiment freely with scale degrees, chord tones, melodic ideas, or improvisation within a clearly defined harmonic setting.

3. Drones – A Simple Tonal Reference

A drone is a sustained tone that provides a constant pitch reference.

Unlike a full backing track, a drone does not need to define a complete chord. It gives you a single reference pitch against which you can hear and explore other notes.

The FET collection includes Cello Drones, using the sound of a cello as the tonal reference.

What can you do with a drone?

Start by listening to the drone and singing its pitch.

Then sing or play another note against it.

Try moving from the drone’s pitch to the second, third, fourth, or fifth above it. Return to the reference pitch whenever you wish.

Pay attention to the relationship between the two sounds.

You can also sustain different notes, explore melodic phrases, or improvise while the drone continues.

The drone gives you a stable point of reference without prescribing a particular melody or sequence of notes.

Drones and Backing Tracks are not the same

Both provide a musical reference, but the reference is different.

A drone establishes a fixed pitch. A backing track can establish a fuller harmonic context through chords and accompaniment.

With a drone, you can concentrate on pitch relationships against a single sustained note.

With a chord-based backing track, you can explore how notes behave as chord tones, extensions, or other notes within the harmony.

Use Drones when you want a minimal tonal reference and plenty of freedom to explore pitches with your voice or instrument.

4. Cheat Sheets – Visual References for Musical Relationships

Although Functional Ear Training is primarily about listening and making music, a little visual information can sometimes be useful.

The free FET Cheat Sheets provide reference material for topics such as:

  • Scale degrees and their names
  • Nashville Numbers and Movable-Do Solfège
  • Chords within the major scale
  • Chord tones and guide tones
  • Modes and their note relationships
  • Harmonic information in different keys

These sheets are not intended to replace listening.

Instead, they help you understand and organize the musical relationships you are exploring.

For example, you might use a Cheat Sheet to identify the notes of a particular chord before playing them over a Backing Track.

Or you might refer to a scale-degree chart when learning to name the notes you hear in a Call-and-Response exercise.

Use the Cheat Sheets when you want to check or understand the musical relationships behind an exercise.

5. iReal Pro Files – Create Your Own Practice Environment

In addition to the audio recordings, FunctionalEarTraining.com provides practice files for iReal Pro.

These files allow you to work with selected harmonic settings inside the iReal Pro app.

The available material includes single-chord exercises for different diatonic chord types, such as major seventh, minor seventh, and half-diminished chords.

Instead of relying exclusively on a prerecorded track, you can use the app’s accompaniment features to adapt your practice session.

For example, you can work with different keys, adjust the tempo, or repeat the harmonic setting while exploring the relevant notes.

This makes the files especially useful if you want more control over your practice environment.

Use the iReal Pro Files when you want to create flexible accompaniment for your own functional ear training exercises.

6. How the Different Materials Work Together

The materials are not separate methods that compete with one another.

They offer different ways of approaching the same fundamental task: becoming familiar with musical notes and their relationships within a tonal or harmonic context.

Consider a simple example: exploring the first three scale degrees of a major key.

You could begin with a Call-and-Response Track that uses only degrees 1, 2, and 3. Listen to the calls and reproduce them with your voice or instrument.

Next, use a Backing Track to explore those same three notes freely, creating your own short phrases rather than repeating prerecorded ones.

You might then use a Drone to concentrate on the relationships between those notes and a single reference pitch, without the additional information provided by a chord.

A Cheat Sheet can help you identify and compare the notes and their functions, while an iReal Pro File can provide a customizable harmonic environment for further exploration.

There is no requirement to use all these materials, or to follow a fixed sequence.

You can choose whichever approach suits the musical question you want to explore.

7. Which Material Should You Choose?

The most useful starting point depends on what you want to practice.

If you want to… Try…
Listen to short musical phrases and reproduce them Call-and-Response Tracks
Learn to associate notes with scale-degree names Call-and-Response Tracks with Nashville Numbers or Solfège
Identify scale degrees without hearing their names Instrumental Call-and-Response Tracks
Experiment with notes over a stable chord Backing Tracks
Explore pitch relationships against a single sustained note Drones
Check chord structures, note functions, or scale-degree names Cheat Sheets
Set up your own adjustable harmonic accompaniment iReal Pro Files

You do not need to master one type of material before moving to another.

The important distinction is between guided practice, where the recording gives you specific musical material to respond to, and open-ended practice, where you create your own musical material against a tonal or harmonic reference.

Both approaches have their place.

8. Listen First, Then Make Music

Functional Ear Training is not primarily about memorizing charts or calculating intervals.

It is about developing familiarity with musical sounds in context.

The recordings and reference materials provide different ways to explore those sounds, but they cannot do the listening for you.

Sing the notes. Play them on your instrument. Repeat them, change their order, experiment with short melodies, and listen to how their character changes in different harmonic settings.

Over time, the goal is to become more familiar with these relationships so that recognizing and using them becomes a natural part of making music.

Explore the sounds, not just the names.
