Keynote speaker: what the role is actually for

The name comes from music, and the metaphor is exact: it sets the key the rest is played in.

A keynote speaker gives the session the whole event attends together, usually at the start of a day and sometimes at the end of it. The word comes from music, where a keynote is the note that sets the key everything else is played in, and the metaphor is exact: the job is to establish the register for the rest of the programme rather than to be the best talk on it.

The two keynote slots and what each one is for An opening keynote reaches the whole audience at full attention and sets the theme for everything after it. A closing keynote reaches a smaller and more tired audience and draws the day together. The bars show roughly what share of the audience is present and attentive at each point. Two slots, two different jobs Opening keynote the whole room, rested, and nothing to compare it against yet Sets the register. Anything it establishes, later sessions are heard against. Closing keynote fewer people, tired, and a day of talks behind them Draws the day together. It cannot set a theme; it can only answer one. Different slots. Different talks.
Roughly who is in the room for each. The two slots are frequently offered to speakers as though they were interchangeable, and they are not.

What a keynote speaker is actually for

Three things, in order of how often they are the real reason. To set a theme the rest of the day can be heard against. To say something the programme could not have commissioned, because it is an argument rather than a report. And, at some events, to draw an audience, which is a marketing function wearing a programme’s clothes.

What it is not for is depth. A keynote is heard by a room containing every level of experience at once, which rules out the technical specificity that makes an ordinary talk good. A keynote that could have been a conference talk is usually a conference talk that got the wrong slot.

Opening and closing are different jobs

Reading the chart, the opening slot has the whole room, rested, with nothing to compare against yet. Whatever it establishes becomes the frame for everything after it, which is real influence and a real responsibility.

The closing slot has a smaller, tired audience who have already heard eight talks. It cannot set a frame because the day has already happened. What it can do is gather the day up, and the closing keynotes people remember are almost always the ones that referred to what had actually been said during it.

A closing keynote written in advance and unchanged has missed its slot.

How a keynote speaker is chosen

Usually by invitation rather than through the call for papers, which is the structural difference between a keynote and every other session. That has two consequences worth stating.

The first is that the choice is made by two or three people from whoever they can think of, which narrows the field to the organisers’ own network unless they work at it deliberately.

The second is that a keynote is one of the few slots an event can use to say what kind of event it intends to be, because it is the one choice the programme committee makes rather than receives. How the rest of the programme is assembled is on the review process.

Payment, and why it varies so much

At regional scale a keynote speaker is usually not paid and often has expenses covered. At large commercial conferences a keynote fee is normal and can be substantial. The gap between those two worlds is wide enough that the same word describes two different arrangements.

What matters more than the fee is that the arrangement is stated when the invitation is made, including whether travel is covered, because a speaker who discovers the terms afterwards is a speaker who does not return. That is covered on the speaker honorarium page.

What it is confused with

A plenary. Every keynote is a plenary session; most plenaries are not keynotes. The plenary is the format, the keynote is the job. See plenary session.

An invited talk. Also by invitation, but programmed among the ordinary sessions and pitched at the depth of one. The difference is the audience, not the invitation.

A sponsored slot. A talk paid for by the company giving it. Where a keynote is sold this way an event has converted its most influential slot into an advertisement, which is examined on community versus corporate.

The rest of the vocabulary is in the glossary, and how a keynote is placed in a day is on programme and tracks.

Questions

What is a keynote speaker?

The person giving the session the whole event attends together, usually opening or closing a day. The name comes from music: a keynote sets the key everything else is played in, and the job is to set the register rather than to be the best talk on the programme.

What is the difference between a keynote and a plenary?

The plenary is the format, the keynote is the job. A plenary is any session the whole event attends; a keynote is a plenary with the specific task of setting a theme or drawing one together. Every keynote is a plenary and most plenaries are not keynotes.

Should a keynote be technically deep?

Generally not. It is heard by a room containing every level of experience at once, which rules out the specificity that makes an ordinary talk good. A keynote that could have been a conference talk usually is one, in the wrong slot.

How are keynote speakers chosen?

By invitation rather than through the call for papers. That makes it the one slot the committee chooses rather than receives, and it also means the field narrows to the organisers’ own network unless they work at widening it deliberately.

Are keynote speakers paid?

At regional scale usually not, with expenses covered. At large commercial conferences a fee is normal and can be substantial. What matters more than the amount is that the arrangement, including travel, is stated when the invitation is made.
