How to Finish a Song and Make a Demo
By Written by Peter McVeigh
Most songwriters have a folder of half-finished ideas. Here is a practical way to work out what each fragment is, finish it, record a demo that does the job, and get the song ready to share.
If you write songs, you almost certainly have a folder full of ideas that never went anywhere. A good chorus with no verses. A verse with no idea where it belongs. A voice memo of a riff you cannot quite remember the point of.
Finishing songs is a skill, and like most skills it gets easier with a method. This is a practical guide to turning a fragment into a finished song, recording a demo that does its job, and getting the song ready to share. It is general advice from a songwriting point of view, so take what fits the way you work.
Why songs stay unfinished
Most songs stall for the same few reasons. Often the idea is only one section and you have not worked out which section it is. Or you keep polishing the first verse and never get to the end. Or you are waiting for inspiration to come back, when really you need to sit down and do the work. And plenty of us start something new the moment the old idea gets difficult.
None of these mean the song is bad. They mean the song needs a plan.
Work out what you actually have
A lot of stuck songs are a section in the wrong place. You might think you have a chorus when you actually have a verse, or the other way round.
A chorus hook tends to be short, repetitive and emotional, and it often sits a bit higher in your range. A verse tends to sit lower and describe a person, a place or a situation, rather than shouting the feeling.
Play your fragment and ask honestly which one it sounds like. Once you know, you know what is missing. A verse needs a chorus to land on, and a chorus needs verses that earn it.
Choose a structure and write the missing parts
Pick a simple shape and write towards it. For most songs that means verse, chorus, verse, chorus, bridge, chorus. You do not need to use every part, but choosing a pathway gives you momentum.
A few things help here. Use repetition, because most songs repeat something in nearly every section. If you have a short musical idea, repeat it and change the chords underneath. Save the contrast for the bridge, which can afford to be different because the rest of the song has been repeating. And tell the story: if your fragment only captures one feeling, such as sadness after a breakup, the other verses are where you explain how you got there.
If you want help with the mechanics, our Song Structure Builder lets you arrange and see your sections, Word Development is useful when the lyric stalls, and Song Starters gives you prompts when you are staring at a blank page. If you are stuck on the chords, Chords In Your Key shows which chords belong together.
Set a finish date
Pick a date and finish the song by then, even if you think it is not good enough. You are allowed to rewrite it afterwards. A finished song you can fix is worth far more than an unfinished one you keep admiring.
It also helps to finish before you start something new. Every song you finish teaches you something about endings, and endings are the part most writers have the least practice at.
Record a rough version straight away
As soon as you have a complete draft, record it. Your phone is fine. Listening back is the quickest way to hear what is working and what is not: the verse that goes on too long, the line that does not scan, the chorus that arrives a bar late.
Do not skip this step. A song that only exists in your head always sounds better than it is.
What a demo is for
A demo is a recording that shows other people what the song is. It might be for a co-writer, a singer, a producer, a publisher or an artist you want to pitch it to.
How good does it need to be? Good enough that a listener can easily imagine the finished record. It does not need to be expensive or fully produced, but it does need a clear vocal and a performance that carries the feel of the song. Out of tune vocals and messy playing can sink a good song before anyone hears what it could be.
Keep the demo simple
For most songs, less is more. A strong guitar and vocal, or piano and vocal, often does more than a crowded band recording, because the listener hears the song itself. Many writers find it better to have a catalogue of well-recorded stripped back demos than a few overproduced ones.
A few practical points. Make the lead vocal easy to hear and do not bury it under guitars. If you are not the right singer for the song, ask someone who is, and pick a voice that suits the song rather than whoever happens to be free. Try not to copy the voice of the artist you hope will record it, because it can end up sounding like an impression rather than a song. Ballads usually work well stripped back, while up-tempo songs sometimes need a bit more arrangement to capture the energy. And attach a lyric sheet with the chords, because words are not always as clear in a recording as you think. Our Chord Chart Generator will set the chords out neatly.
Before you share it
Before the song goes to anyone, tidy up the business side. Agree the splits with anyone who helped write it, in writing, and our songwriting split agreement tool is a good starting point. Keep dated copies of your files and notes of who wrote what. And if you are a PRS member, register the song so it has a tunecode. Our guide on what a PRS tunecode is explains why that matters.
It takes an hour and saves a lot of arguments later.
Common mistakes
The mistakes I would watch for are polishing the start of the song and never finishing the end, waiting to feel inspired before you sit down, sending a demo with a quiet vocal or poor tuning, overproducing a demo for a song that works with one instrument, and sharing a song before the splits are agreed.
What to do next
Open your folder of ideas and pick one. Decide whether it is a verse or a chorus, set a date, and write the missing parts. Record a rough version the same week, then make a proper demo once the song is solid.
Once you have a finished song and a decent demo, you are ready to think about who might want to hear it. Our guide on how to pitch your songs to publishers, sync libraries and artists covers that next step.
