Quick answer: How to write a song on guitar: pick a key and a simple four-chord progression, strum a rhythm you like, hum melodies over it until one sticks, then write lyrics around one clear idea. Arrange it as verse, chorus, verse, chorus, bridge, chorus, and record a rough phone demo so you don’t lose it.
You don’t need years of lessons to write a song. If you know four or five open chords, you already have everything you need. Here’s the step-by-step method I use and teach. If you want help with ideas, see our AI music generator guide.
What do you need to start writing songs on guitar?
- A guitar that stays in tune.
- A handful of open chords (G, C, D, Em, Am). See beginner guitar chords.
- A way to record ideas (your phone’s voice memo app works fine).
- A notebook or notes app for lyrics.
- Optional: a capo, so you can change keys without learning new shapes.
How to write a song on guitar, Step 1: Pick a key you can sing in
Strum a G chord and sing a few notes. Too low or too high? Move a capo up a fret or two until it feels natural. Your voice decides the key, not the guitar.
Step 2: Choose a chord progression
Thousands of songs use the same handful of progressions. That’s good news, because it means you can borrow one and make it your own.
| Progression (numbers) | In the key of G | Feel |
|---|---|---|
| I – V – vi – IV | G – D – Em – C | Uplifting, pop and worship staple |
| vi – IV – I – V | Em – C – G – D | More emotional and reflective |
| I – IV – V | G – C – D | Classic rock, folk and country |
| I – vi – IV – V | G – Em – C – D | Fifties ballad, nostalgic |
| ii – V – I | Am – D – G | Smooth, used in jazz and pop |

Step 3: Find a strumming pattern and tempo
The rhythm sets the mood more than the chords do. A slow down-strum on each beat feels like a ballad. A busy down-down-up-up-down-up pattern feels upbeat. Try the same progression at three different speeds and pick the one that matches the feeling you want.
Step 4: Hum a melody before writing words
Loop your progression and hum or sing nonsense syllables over it. Record two or three minutes. Most of it will be forgettable, but usually a few seconds will jump out. That’s your melody seed.
Tips for strong melodies:
- Start the verse lower and let the chorus climb higher.
- Repeat a short melodic phrase, then change its ending.
- Leave space. Rests make a melody easier to remember.
Step 5: Decide what the song is about
Write one sentence that sums up the song: “This song is about ___.” If you can’t finish that sentence, the listener won’t be able to either. Then write a title line that says it in five words or fewer.
Step 6: Write the chorus
The chorus states the main idea, usually with the title in it. Keep it short and repeatable. Fit your title line onto the strongest part of the melody you found in Step 4. Writing the chorus first gives every other section a target.
Step 7: Write verses that support the chorus
Verses give details: who, where, what happened. Use concrete images (“coffee on the dashboard”) rather than abstract ones (“I felt sad”). Each verse should move the story forward so the chorus means a little more each time it comes back.
Step 8: Arrange the song
A common structure that works for most beginner songs:
- Intro (4 bars of the chorus chords)
- Verse 1
- Chorus
- Verse 2
- Chorus
- Bridge (new chords, such as starting on the IV or vi)
- Final chorus
See more options in popular song structures, and learn timing in when to change chords in a song.
Step 9: Record a demo and revise
Record the whole song in one take on your phone. Listen the next day with fresh ears. Ask yourself:
- Is the chorus the most memorable part?
- Does any line feel like filler?
- Does the song drag anywhere?
Fix one thing at a time, then record again. When you’re ready for a better-sounding demo, check out my guide to a recording software for guitar.
How do I get unstuck when songwriting?
- Change the instrument voice: try a capo high on the neck, or a new tuning.
- Change the rhythm: switch from strumming to fingerpicking.
- Set a timer: give yourself 20 minutes to finish a rough verse, good or bad.
- Write from a title: make a list of 10 possible titles and pick one to write toward.
- Co-write: another person’s ideas break your habits quickly.
