When 5 doesn't go home: how to hear 6m

By Adrian · 6 October 2026 · 5 min read

After 5, the ear expects home. Sometimes the song lands on 6m instead: home, but not the home you knew. Once you can hear that surprise, 6m becomes one of the easiest chords to recognise.

5 is tension: a chord you can't stay on, that wants to go back to 1. (If that's new to you, start with Nashville numbers explained, and if 4 and 5 still sound alike, read How to tell 4 from 5 by ear.)

Home, but not the home you knew

Here I go into classical theory for a moment. At the end of a phrase, after 5, the listener expects us to go back home, to 1. But sometimes we want to surprise them, and most of the time we do it by going to 6m. Classical theory calls this a deceptive cadence. Listen to both:

It feels like you've arrived home, just not at the home you knew.

That's why it works. 6m is a rest chord: it shares two notes with 1, so the tension of 5 does find a place to land. It's just not the place the ear was waiting for.

How to spot 6m

I don't have a special exercise for this. I tell my students one thing:

If you hear a chord that doesn't sound like 1, 4 or 5, or doesn't even sound major, there's a good chance it's 6m.

6m is fairly easy to feel, especially when 5 comes right before it: they're neighbours, one step apart. Try it. Each card below plays four chords in the key of G. Which is the last one: home, or the surprise?

Amazing Grace, with a surprise ending

You may know this one from Nashville numbers explained: Amazing Grace in G, the way I play it. This time we sing the last line twice. The first time, 5 doesn't go home: it goes to 6m. The second time, it goes home to 1. Press play on a line, or play the whole verse.

Now follow the surprise:

• The first time, "see" lands on 6m. After 5⁷ the ear waits for G and gets Em. The melody sings the same G as always, but the chord under it has changed: you've arrived home, just not at the home you knew. And the song can't end there.
• The second time, it goes home: the same words, the same melody, the same 6m and 5⁷, and this time 1. After the surprise, coming home feels earned.

Try it the next time you play Amazing Grace: it only takes one changed chord.

When you start to recognise it

Students don't necessarily say anything when they notice it. You see it in how they play: they're applying something they've taken in.

Sometimes they play two songs one after the other where 5 brings the same obvious tension, or where the step from 1 to 4 feels just as clear. Then, while they pulse that new chord they felt and chose themselves, for a few seconds they realise the music comes from them. At least until the next chord of the song, which they have to find and bring to the listener's ears.

That's what recognising moments like 5 going to 6m gives you: fewer chords to work out, and more of those moments.
