The technique · 1 of 5

Start with a drone, not a song

Play a sustained single note. Sing a third above. Then a fifth. Then an octave. Hold each for eight seconds and listen for the beating disappearing as you tune. A drone does not move, which makes it the correct first rung.

Pick something that alternates between two chords, and there are hundreds. Sing the root of whichever chord is sounding, ignoring the melody entirely. You are training chord tracking, not harmony yet, and this step is where most of the real progress happens.

Same song, now find the third of each chord. This is usually the sweetest harmony note and it requires you to actually identify the chord rather than just hear the bass, which is the skill that unlocks everything after it.

Now bring the melody in at low volume while you sing your chord tone. Low volume first. If you drift onto it, turn it down further. This is the interference ladder and skipping it is why so many people can harmonize alone and not with others.

Sing your harmony over a recording, record the result, and listen back. Harmony sounds different from inside your own head than it does in the room, and the recording is the only honest referee.

Read at your pace. The guided practice comes next.

Why this exercise · 1 of 11

The idea behind it.

People who harmonize instinctively are usually described as having a gift, which is discouraging and mostly wrong. What they actually have is three separate skills stacked on top of each other, all of them learnable, usually acquired unconsciously through years of singing with family or in a choir.

If you did not get them by osmosis, you can get them deliberately, and it goes faster when you know they are three things rather than one.

The first skill is hearing the underlying chord. Harmony is not a fixed distance above the melody; a constant third above will collide with the chords within a few bars. What you are actually doing is picking a note that belongs to the current chord and is not the one the melody is on.

So the foundational skill is hearing when the chord changes and having some sense of what it changed to.

The second is choosing quickly.

Once you can hear the chord, the available harmony notes are usually two or three, and the choice is governed by voice leading: prefer the closest available note to where you just were, prefer contrary motion to the melody when it is available, and avoid crossing above the melody unless you intend to.

The third is holding your note while the melody sounds next to you, which is a completely separate skill and the one most people fail on. You can know the right note perfectly and still slide onto the melody within four bars, because your pitch-correction loop re-targets onto the loudest reference available.

Most harmony instruction teaches intervals above the melody, sing a third up, which works for about four bars and then collides with the chord progression.

Harmony is a vertical relationship with the chord, not a horizontal offset from the tune, and teaching it as a fixed interval produces singers who are confidently wrong in the second half of every verse.

Harmony demands more pitch precision than melody, because a harmony note that is fifteen cents off sounds noticeably sour against a sustained chord in a way the same error on a melody does not. The free pitch test gives you your current precision in 60 seconds.

Vocal School has the largest harmony block in its curriculum: thirds, fifths, holding against a melody, part independence, blend tuning, and just intonation, each gated behind the one before. Free tier: one full session a day.

What did you notice?

Can you hear the chord change in a song you do not know, without an instrument? Hum along with the bass line. If you can follow it, you have the foundation, and what remains is choosing notes and holding them. If you cannot yet, that is the thing to practice first.

An observation, not a diagnosis. No answer is required or scored.

Choose a snapshot.

Pitch matching and range are separate measurements. Neither identifies the physical cause of a vocal problem.

Both return to this guide. Stop and rest if your voice feels strained.
