Although 4/4 is by far the most common time signature, another popular choice for music through the ages and including the modern day is 6/8. Why is this time signature distinctive, how does it work, and how can you learn to hear and play it? That’s what we’ll be digging into in this 6/8 tutorial.
Have you struggled to understand time signatures in music? Wondered why a piece is written in 4/4 instead of 2/2, or if a composer using 6/8 is just trying to make your life difficult? Time signatures are as fundamental to a piece of music as its key signature. Before you can worry about the intricacies of rhythm you need to be rock-solid on the underlying beat. To do that, you’ll need to know what the time signature is and how to count it.
We often expect pop and rock music to be written in the classic 4/4 beat, but it turns out a surprisingly large number of songs we all know and love actually use 6/8.
On first encounter 6/8 can seem complicated and even baffling but, as we’ll see below, there’s really not much to it and there is a fun and easy way to get the “feel” of 6/8 for your own music-making.
Read on for the essential explanations and then plenty of listening examples to practice with.
How to count in 6/8
There are two ways to count a bar in 6/8 time. This can seem unnecessarily confusing when you first encounter 6/8, but as we’ll see the difference is not as big as it first appears.
You can either count it as:
- 6 eighth-note beats: 1,2,3,4,5,6
- 2 dotted-quarter-note beats: 1… 2…
6/8 counted as six eighth notes
6/8 counted as two dotted quarter notes
At first this might seem like two very different ways of counting: in the first case you’re counting out six beats every bar, while in the second case just two. However, when you count all six you actually emphasise beats 1 and 4, so it’s more like 1, 2, 3, 4, 5, 6. Those two places correspond to where your two dotted-quarter note beats would fall so you are emphasising those two beats even if you’re counting out all six.
Likewise, when you count just the two beat version, in your head you would actually be thinking of the subdivision of each of them into three, meaning you’re feeling each of the six eighth-note beats even if you aren’t speaking them.
So whether you count out all six beats or just the two emphasised ones, you are still feeling the same pattern: two groups of three eighth notes.
Why are both options used? It mostly comes down to tempo, and sometimes the musical arrangement. When the piece is very fast it’s too much of a mouthful (or mental challenge) to count out every eighth-note beat and it’s easier to just count the two emphasised beats each bar. Some pieces have an arrangement, for example a guitar strumming pattern, which gives a musical feel that matches one style of counting or the other. Read on for some song examples.
How 6/8 is different from 2/4
One other area that causes confusion with 6/8 is: if you’re counting just the two main beats, isn’t that the same as a 2/4, two beats per bar?
The answer lies in the subdivision of the beats. We call 2/4 time “simple duple” meaning there are two beats per bar and each beat divides in two (the “simple” part). By contrast, 6/8 time also has two quarter note beats per bar so it’s “duple” too, but each one divides into three, making it a “compound duple” time signature.
In other words, although in both cases you’re counting “1, 2, 1, 2, 1, 2, etc.” in the 2/4 time signature each of those beats would divide in two (e.g. “1 and 2 and 1 and 2 and”) while in the 6/8 time signature each one divides in three (e.g. “1 and ah 2 and ah 1 and ah 2 and ah”).

How 6/8 is different from 3/4
Similarly, you might wonder if those 6 eighth notes could be grouped together as three groups of two rather than two groups of three.
Well, you could group them like that, but because you’re dividing each of the three beats into two, it’s then “simple” meter again. With three beats each divided in two, what you actually have is 3/4 time!
This is the difference between 3/4 and 6/8. Although it might seem like numerically they are interchangeable (there are six eighth notes in a bar), the grouping is different. If the rhythms used in the piece group emphasise the first and fourth of those eighth notes, implying they are grouped in threes, it’s 6/8. If the rhythms emphasise just the first (and perhaps the third and fifth), it implies the eighth notes are in groups of two, and the time signature will be 3/4.

Getting the hang of 6/8
What we’ve covered above is pretty much all the music theory behind 6/8. As you can see, there really isn’t much to it! Apart from the small points of confusion noted here, it’s not actually the concepts which cause trouble for musicians.
The challenging part of 6/8 time is learning to recognise it by ear, or learning to express it yourself when reading from sheet music.
That requires the basic theory understanding covered above, but it mostly comes from getting very familiar with the feel of 6/8.
How to hear and feel a 6/8 time signature
There are a few clues that a song is in 6/8. These are also things to think about when playing 6/8 yourself.
The main attribute of a 6/8 time signature is that it has a waltz feel, very different from a left-right marching feel of a 2/4 beat or the steady straight-laced feel of a 4/4. Although it has a waltz feel it’s not as rigid as the traditional 3/4 waltz.
Another useful word used to describe 6/8 is shuffle or lilting. It feels looser and a bit more playful than a 3/4 time signature.
You can hear how the bars each split into two halves. You might even initially hear it as two separate bars of 3/4 time (“1,2,3, 2,2,3”) before realising that the bars always pair up in twos. You can also listen for how each emphasised beat sounds a bit like a triplet because it’s divided in three rather than two. It would be easy to initially think a 6/8 song was actually a song in 2/4 (or 4/4) which used a lot of triplet rhythms.
Your thinking process for recognising 6/8 might look like this:
- Notice that there are 6 beats per bar
- Listen for whether the first and fourth are emphasised (i.e. two groups of three) or the first, third and fifth (i.e. three groups of two). If it’s the first, it’s 6/8, otherwise it’s 3/4.
- Notice that there are 2 beats per bar
- Listen for whether each beat seems to subdivide into two or into three. If it’s two then the time signature is 2/4, if each divides into three then it’s 6/8.
You won’t have to think through the steps like this for long. In time you will just instinctively recognise the 6/8 pattern when you hear a song.
Ultimately the best way to get the hang of 6/8 is just lots of practice. Choose to play pieces in 6/8, or simply listen to songs in a 6/8 feel and practice counting along with the beat. We’ve collected a number below for you to practice with.
