How to Write Your First Song (And Get It Out of Your Head)

Start With What You Have

You don't need to know scales, modes, or the circle of fifths to write a song. You need a melody — even just a fragment of one. Maybe it's a chorus hook, maybe it's the first line of a verse with a tune already baked in. That's enough.

Hum it. Sing it out loud. Get it out of your head and into the air. Pay attention to where it wants to go — where it feels like it resolves, where it feels like it's reaching for something. That intuition is your guide. Trust it.

Find the Chords That Fit

Pick up your guitar (or sit at a piano) and start hunting for notes that match your melody. This isn't analysis — it's translation. You're moving what's in your head to your hands.

As you do this, you'll naturally gravitate toward a key. A key is just the neighborhood your song lives in — a small set of notes, and more importantly, a small set of chords, that all belong together. When a chord feels like "home base" — the place your melody wants to land and rest — that's your key chord, and it tells you what key you're in.

If you're on guitar and the home chord feels like G, you're probably in G major. If it feels like A minor, you might be in A minor. Don't overthink it. Sing the melody, play a few chords, and notice which one feels like the end of a sentence.

The Circle of Fifths — Your Chord Map

Once you know your key, you know your cast of characters. Every key comes with a set of chords that naturally belong to it — they share the same neighborhood of notes, so they all get along with each other.

In G major, those chords are: G, Am, Bm, C, D, Em. That's it. Six chords, and almost any G major song you've ever heard is built from some combination of them.

The circle of fifths is a diagram that maps all of this out — which keys are related, which chords belong to each key. It looks complicated at first, but the idea is simple: pick a key, and it shows you exactly which chords are available to you.

Build a Chord Progression

A chord progression is just the order you play the chords in. Most songs — including some of the biggest hits ever recorded — use only three or four chords. You don't need more than that.

Here are a few progressions to try in G major. Strum each one slowly and sing your melody over the top:

If one clicks with your melody, you've found your progression. If none feel quite right, try a different key — maybe your melody sits naturally higher or lower than G. The rule is simple: if it sounds right to you, it is right.

Place the Chords on Your Lyrics

Now you need to figure out where the chord changes happen in your lyrics. This is where a chord chart comes in — it's a lyric sheet with the chords written above the words, right at the spot where your fingers change position.

Chord changes usually feel natural at:

• The start of a new line
• On a stressed syllable — the part of the word you'd emphasize when singing
• At a natural pause or breath in the phrase

Sing through your lyrics with the guitar and pay attention to where your hand wants to change chord. Those are your chord positions.

Get It Down Before You Forget It

Here's the mistake most songwriters make at this stage: they think they'll remember it. They don't. Write it down now, while it's fresh.

Open MyChordSheet, type your lyrics in, and place each chord above the syllable where it lands. You've got a proper chord chart in minutes. If you later realize the key doesn't suit your voice, transpose it with one click — every chord shifts instantly, and nothing moves out of place. Export a PDF to take to rehearsal, or share it with your bandmates.

The song that lived in your head is now a document you can hand to another musician. That's the whole job.
