Vocal-First Demo: Recording the Voice Before the Chords
人声优先小样：先录人声，再贴和弦 — 用中文读这一篇
Most demos are built from the instrument up: chords first, then a vocal on top. Recording the vocal first inverts that order and produces a demo that answers a different question — not 'does this sound good' but 'can this be sung'. The second question is much harder to answer later.

Record the vocal alone, from memory
No instrument, no reference pitch, no headphones. Sing the whole song from memory into a single microphone and let the key land wherever it lands. Do not stop to correct the key. You are trying to capture the version of the song that exists in your body rather than the one in your notes.
Almost everyone ends up a step or two below the written key. That is not a mistake — it is the first real information about the song's register.
Then add the instrument to the vocal
Play the chords along with your recorded vocal rather than the other way around. You will find that the chord placement you wrote does not match where the melody actually breathes, and those mismatches are the most valuable output of the exercise.
Do not fix them by re-recording the vocal. Fix them by moving the chord — usually a bar of the loop needs to shift by one beat, or the chorus needs to arrive half a bar earlier.
| Mismatch you find | Usual cause | Fix |
|---|---|---|
| Chorus feels late | The melody anticipates the downbeat and the chords do not | Move the loop one beat earlier |
| A verse line sounds rushed | The chord change lands mid-phrase | Move the change to the phrase boundary |
| The bridge does not lift | The vocal sits lower than written | Transpose the song down and lift the bridge instead |
| The hook sounds weaker than in your head | The sung rhythm differs from the notated one | Notate the sung rhythm; it is almost always better |
What to do with the key it landed in
If the vocal-from-memory version is a whole step below the written key, that is probably the song's true key, and the written key was an artefact of playing the chords before writing the melody. Transpose the whole song and re-check. Songs that are transposed down at this stage usually gain a usable chorus top note and lose nothing else.
The one case where you should not transpose is when the chord voicings depend on open strings. In that case use a capo and keep the sounding key, or accept the higher key and rewrite the peak of the chorus to stay below it.
When to abandon the demo
If the vocal-first demo reveals that the song cannot be sung comfortably by anyone, including you, in any key — usually because the verses and the chorus occupy the same three notes and there is nowhere to put a melody — then the demo has done its job perfectly. The song needs rewriting, not recording, and finding that out in twenty minutes is a good outcome.
Keep the recording anyway. Roughly half of these songs come back six months later with a new chorus and the original verse vocal intact.
Carry these
- Record the vocal alone from memory first, then fit the chords to it — not the other way around.
- Mismatches between chord placement and the sung phrasing are the exercise's real output.
- If the remembered version lands a step lower, that is probably the song's true key.
Questions that come up here
I cannot sing accurately without a reference pitch. Does this still work?
Yes, and it is arguably more useful. Singing without a reference exposes your natural phrasing, which is the thing the exercise is for. The pitch itself does not matter — measure it afterwards with a tuner app and you will have the song's true key, which is the second output.
Should I do this for every song?
Do it for any song where the chorus feels like a stretch to sing, and for any song you have written primarily on an instrument. Songs written while humming or walking rarely need it, because the melody was already the starting point rather than something fitted to chords.
