A guesthouse writes a welcome post on Monday and an apology for a broken boiler on Wednesday. If both sound the same, one of them is wrong.
If they sound like two different businesses, something else is wrong. Readers notice both: the cheerful apology and the stranger who suddenly writes the brand's posts.
The way out is to separate two things that guides often blur. Voice is who is speaking. Tone is how that person speaks in a given moment.
01The difference
Voice is the person. Tone is the moment.
Think of someone you know well. They talk differently at a birthday and at a funeral, but you would recognise them in either room. Their vocabulary, their way of noticing things and what they would never say stay put.
A brand voice works the same way. It holds the choices that do not depend on the occasion: whether the brand says “you” or “guests”, whether it uses humour, which promises it never makes.
Voice
We say “you”. We name the detail. We never promise what we can't control.
Tone
Lighter for a new breakfast menu, plainer for a delay, warmer for a thank-you.
When a guide mixes the two, it ends up with rules like “always playful”. That rule breaks the first time the brand has bad news to share.
02The moments
List the moments before you set the tone.
Most small brands write in a handful of recurring situations. Name them, and the tone question becomes much smaller.
- Invitations.A new offer, an event, an open slot. Room for warmth and a little play.
- Information.Opening hours, prices, changes. Plain first, friendly second.
- Apologies.Something went wrong. Clear, specific, no jokes.
- Thanks.A milestone, a review, a regular. Personal, short.
For each moment, write one sentence on how the tone shifts and one approved example. That is often enough for a new writer to find the right register.
03The test
Test the voice on the hardest post first.
A voice that only works for happy posts is a mood, not a voice. Try it on the post nobody wants to write.
The same broken boiler. Two apologies.
First draft
Oops! Our boiler decided to take a holiday too 😅 Hot water is back soon, promise!
A joke where the guest is cold. A promise without a time.
The revision keeps the brand's habits: it speaks as “we”, names the detail and avoids promises it cannot keep. Only the tone has changed.
If a reader can't tell who wrote the apology, the voice isn't written down yet.
04The guide
Keep voice and tone in separate places.
In a guide, put the voice at the top: a few lasting choices with examples. Put the tone below it, as the moments and how each one shifts.
In Kanso, the voice lives in the brand's Brand Brain, with approved examples and the reasons behind them. Every draft starts from it, whatever the moment.
If your guide is still a list of adjectives, start with turning them into decisions, then map the moments.
