Intro.

British band Glass Animals are absolutely massive! At the time of writing this, they’re ranked #257 in the world on Spotify. Most artists as famous as them have achieved their success as a result of an obsessive striving for celebrity. However, Glass Animals seem to be obsessed with making catchy music instead. And not only that, their music is surprisingly creative for a band as successful as them.

If you’ve been doing our Hack Music Theory tutorials for a few years, you’ll know that we don’t usually cover “celebrity artists”. The reason for that is because (nowadays) there’s an inverse correlation between the success of an artist and the creativity of their music. For an artist to achieve a fanbase of tens of millions, their music needs to appeal to the masses. And most people (nowadays) want “sugary” ear-candy music that’s pleasantly predictable, i.e. boring, bland background music.

So why are we doing a tutorial on such a huge band? Well, Glass Animals’ new single “Creatures in Heaven” is a masterclass in catchy melody writing. The lead melody in their chorus has a whole bunch of creative hacks, as well as a very clever twist in its tale.

So, inspired by “Creatures in Heaven”, here’s our 6-step method for writing a great melody that’s catchy enough for the masses. But first… Tea!

Step 1. The Chords

Open your DAW, leave the time signature on 4|4, but change your tempo to 80 BPM. Next, create a four-bar loop on your melody track, with a 1/16 grid. Okay so you may be wondering why the first step in a melody tutorial is… the chords?!

Well, all great melodies are written over chords, or implied chords (chords are “implied” when they’re not played separately but their notes are incorporated into the melody instead). The reason it’s best to write a melody over chords is because it gives the melody a harmonic progression. Without this progression, the melody will sound mind-numbingly boring, as it won’t go anywhere harmonically. The difference is night and day. It’s like walking through a beautiful forest along the ocean compared to walking on a treadmill in a stinky gym. There’s no comparison!

So let’s get our chord progression written, that way we’ve set ourselves up to write a great melody. Glass Animals are in the key of D major for their chorus (so we’ll use it too), and they use four chords in their progression (so we’ll do that too).

D Major (notes)

1	2	3	4	5	6	7
D	E	F♯	G	A	B	C♯

D Major (chords)*

1	2	3	4	5	6	7
Dmaj	Em	F♯m	Gmaj	Amaj	Bm	C♯dim

As you probably know (or as you’ll hear if you play it), the diminished chord is crazy dissonant. It’s safe to say that using C♯dim ain’t gonna appeal to the masses, so take that off your menu. But other than that, you can use whatever you want.

Glass Animals use all three major chords, and only one minor. Playing three major chords in a major key gives their chorus a wonderfully uplifting vibe. So, think about your balance between major (happy) and minor (sad) chords. Also, think about the order of your chords. Glass Animals play the root chord (Dmaj) second. This detracts attention from it and creates a more fluid atmosphere. We played Dmaj last, though, which creates a more final ending. You can play Dmaj wherever you want, but consider where you want to draw people to the “home” chord. Here’s our progression: Gmaj → Bm → Amaj → Dmaj

*If you need help working out the chords in a key, read Hack 10 in our Free Book.

Once you’ve chosen your four chords, draw in the root note of each chord for a full bar (in a low octave). These roots will provide harmonic reference for your melody, which you’re gonna write above. This way you’ll be able to hear the relationship between each note in your melody and its accompanying chord. When you’ve finished writing your melody, mute these low roots. Then, create another track specifically for your progression, and draw in each full chord (i.e. 1, 3, 5).

Step 2. The Drama

Great melodies contain drama, and there’s no better way to bring the drama than by using a big interval.* You see, larger intervals create intensity, while smaller intervals create continuity. You need both. In fact, you need a lot more smaller intervals than bigger intervals. However, if your melody contains only small intervals, it’ll be awfully boring. On the other hand, if your melody contains only big intervals, people will presume you were thoroughly drunk when you wrote it.

Over your first chord, write a handful of notes that end with a big interval around beat 3. And that big melodic jump should go up, not down (a large descending interval contains only a fraction of the drama of that same interval ascending).

Be sure to begin your melody on beat 1, as this will make the most impact, and as this section is the chorus, first impressions matter even more than usual. Use a combination of note values for interest. And remember, if you wanna emphasize a chord’s major (happy) or minor (sad) vibe, then play its 3rd in your melody above.

Step 3. The Fall

You’re now gonna finish your melody’s first phrase with “the fall”. This is an utterly brilliant technique that Glass Animals use in their melody. And, it makes for a deeply pleasing balance between the drama and the gentle ride down afterwards.

Your last note is currently that high note around beat 3, so now you’re gonna write a smooth contour that flows back down to somewhere around where you began.

All good melodies have phrasing (i.e. where the melody rests), regardless of whether they’re sung or played on an instrument. This is because the melody itself needs to breathe, not just the singer. These rests also break-up a melody into digestible bits (i.e. phrases), which makes it easier to remember. So, end your first phrase on a longer note, and have at least a 1/16 rest at the end of your first bar (i.e. beat 4a). You can have an 1/8 rest if you prefer, but nothing longer than that, otherwise you’ll lose the momentum.

Notice how we didn’t play the chord’s root (G) in our melody. That root will be played in the chords below, so you don’t need to play it unless you actually want to.

Step 4. Rhythmic Variation

Copy and paste your first phrase into bar two, and make sure to also start it on beat 1. Glass Animals use a great hack in their second phrase, which makes it familiar to the listeners while simultaneously freshening it up so it’s not boring.

They achieve this by using rhythmic variation. Simple, but massively effective. By only changing a few note values, the phrase is both predictable and unpredictable.

Repetition is vital if you wanna appeal to the masses. People love a melody they know. But, too much repetition will make a melody predictable. And as soon as it’s predictable, their attention will move to some other novelty in their environment; probably their phone (it’s a sad reality that music is competing with phones for people’s attention). So it’s essential to repeat your melody for it to get stuck in their heads, and rhythmic variation will prevent it from losing its novelty and appeal.

Glass Animals change almost all their note values, but only slightly. Let your ear guide you into the Goldilocks Zone in this step, as too much change will make the phrase sound unfamiliar, while not enough change will make it sound predictable.

Lastly, Glass Animals add one new note at the end of their phrase, so it actually finishes on the last beat of the bar. This new note is a 1/16, which is completely unexpected, so it adds to the novelty. We did this too, but you don’t have to. If you don’t, though, then extend your last note so it also finishes at the end of the bar.

Step 5. The Climb

We’re halfway through our melody now. And after two phrases that “fall”, Glass Animals counters that with a phrase that “climbs”. In the same way that the notes in our “falling” phrase aren’t all descending, the notes in our “climbing” phrase don’t all have to be ascending either. But, there needs to be an overall climbing contour and feel to it. So, you’ll wanna start this phrase slightly lower than your “falling” phrases, and then play around with writing a generally ascending contour.

Also, Glass Animals start this phrase on beat 1+, which is another way of adding novelty and interest. We did the same. You don’t have to start there but you do have to start on an off-beat, as your previous phrase ends right at beat 1. And your melody needs a breath there, so your only other options are beat 1e or beat 1a.

Before you jump in and begin writing this phrase, there’s one more guideline. After their climb, Glass Animals actually take their melody down a big interval. In fact, it’s the exact same big interval they use in their first phrase, but this time it jumps down instead of up. This provides a clever mirror image, which is utterly brilliant, but most people won’t notice that. What is noticeable, though, is how this low note extends the range (i.e. distance from lowest to highest note) of their melody.

Good melodies usually have a range of about an octave. This ending note is the last opportunity to extend your melody’s range to somewhere around an octave.

Step 6. Melodic Structure

This final step is a game-changer! You see, when we hear Glass Animals’ third phrase (i.e. the “climbing” phrase in Step 5), we obviously perceive it as a new phrase because it’s totally different. This is a common structure used for melodies. It’s known as AABA, where A is the first phrase and B is the second phrase. So in other words, the first phrase is played twice, then there’s a new phrase, and then the first phrase is played again (for the third time). By the way, it’s equally common to hear AAAB, where the first phrase is played three times in a row, followed by the second phrase. Okay, this Glass Animals melody seems normal so far, right? Yes. But (and it’s a BIG “but”), in this fourth bar where everyone will be expecting the return of their first phrase, Glass Animals repeat their second phrase instead.

By doing this, they actually transform their second phrase from being a “variation” to being an equally-important main phrase. So, this melody now consists of two main phrases: the first one that’s repeated in bars one and two, and the second phrase that’s repeated in bars three and four. This is known as an AABB structure.

This structure is surprisingly rare compared to the far more common AABA or AAAB. When it’s done well, the AABB melodic structure can take the catchiness of a melody to a whole new level. When done wrong, though, it can make a bad melody even worse. That’s because if you want your B phrase to be equal in importance to your A phrase, then it has to be equally well-written. However, most songwriters/producers approach their variations as nothing more than a variation. In other words, they feed you catchy stuff in their A phrase, then give you bland filler junk in their B phrase, and then they quickly bring back their catchy A phrase.

You’ve probably noticed this already, but what’s so clever about Glass Animals’ melody is that they balance two “falling” phrases (AA) with two “climbing” phrases (BB). This symmetry is beyond pleasing to our ears. Almost nobody will notice this, but everybody will notice how perfect their melody sounds and feels!

Right, let’s get your melody finished. So, copy and paste your B phrase (bar three) into bar four, starting on the same off-beat. This step is the same as Step 4. You’re gonna use rhythmic variation to create a freshened-up version of your B phrase.

At the end of bar four, Glass Animals add another note, just like they did at the end of bar two. We actually added two notes (see MIDI below), but do whatever works for your melody, to create a smooth flow when it loops back to bar one.

With that, you’re done. Thanks for reading, we appreciate you and hope you had fun. Are you ready to sing along to your mass-appealing melody? Hit play & enjoy!
