This chapter's central claim — the four causes of an empty dance floor, in that order — is the author's, and it is not measured. The mechanisms underneath it (social proof, activation cost, behavioural thresholds) are well-studied fields; the ranking is practice. Exercise C.1 exists so that you can gather your own evidence, and exercise E.1 asks you to check the literature honestly.

Tier 1 — Verifiable published sources

Why people start dancing — the mechanisms under §22.7

Granovetter, Mark. "Threshold Models of Collective Behavior" (1978), American Journal of Sociology. The single most relevant academic paper to this chapter. It models exactly the situation a dance floor presents: individuals with different thresholds for joining, where each person's decision depends on how many have already joined. §22.7's "permission" is Granovetter's threshold problem in a barn.
Cialdini, Robert. Influence. On social proof. Popular rather than technical, and the chapter on social proof is directly applicable.
Sugarman, Jonathan and others, on the "first follower" phenomenon in crowd behaviour. Search terms: social contagion, behavioural cascade, first follower. The observation that the second person to join matters more than the first is real, is studied, and is exactly why §22.7 says the couple must stay on the floor.
Any current work on collective synchrony and dance — there is a genuine literature in music psychology on entrainment and group movement, and it is more interesting than the wedding industry's version.

Music and emotion

Levitin, Daniel. This Is Your Brain on Music. Accessible, and good on why familiarity does so much of the work at a wedding.
Juslin, Patrik N. and John Sloboda (eds). Handbook of Music and Emotion. The serious reference. The chapters on musical expectancy explain why a change at the entrance (§20.4, §22.5) works so reliably.
Huron, David. Sweet Anticipation: Music and the Psychology of Expectation. For understanding what a musical cue actually does to a room.

Sound, volume, and hearing

Chapter 18's list applies in full — the Yamaha Sound Reinforcement Handbook, AES speech-intelligibility work, and the WHO noise guidelines.
WHO and NIOSH guidance on recreational noise exposure. A wedding dance floor at 95–105 dB(A) for ninety minutes sits inside the range where sustained exposure matters. Worth knowing, and worth mentioning once to a couple with elderly guests or small children.

Live performance and event production

Vasey, John. Concert Sound and Lighting Systems. For understanding what a band actually needs and why load-in takes three hours.
Any current text on event production management, for the vocabulary of sets, breaks, changeovers, and riders. A band's rider is a document planners are routinely handed and rarely read properly.

Music licensing — the one legal item

PRS for Music and PPL (UK) · ASCAP, BMI, SESAC, and GMR (US) · equivalent collecting societies elsewhere. Establish what your venues' licences cover and what they do not — exercise E.2. It is a real question, it has a real answer, and almost no planner can state it.

Tier 2 — Attributed professional practice

The four music problems. A teaching framework, not a standard. The claim that dinner is the hardest is the author's and is contested by roughly half the DJs who hear it — which makes it a good thing to ask about (exercise C.2).
The four causes of an empty floor, in that order. The author's ranking. The mechanisms are well-founded; the ordering is practice, and exercise D.2 argues against it seriously.
The peak at two-thirds, and the 40–70 minutes before a curfew override. Practice. The override is better founded than the two-thirds figure, because its basis is Chapter 18's boundary arithmetic rather than a feel for a room.
$3,000–$6,000 as the true DJ-versus-band difference. Derived from the components rather than observed. The structure of the calculation is the point; the numbers are your market's.
30–60 seconds per processional unit (inherited from Chapter 20), 3–6 minutes per scheduled moment, and the 10–20 minute window after the last course. All practice.
"An object is not a plan." From Case Study 22.1, and it generalises: a playlist, a spare bulb, a first-aid kit, and a fire extinguisher all do nothing until somebody's name is next to them. This is Chapter 27's rule extended from actions to things.
The five do-not-play questions. The author's, and they work.

Tier 3 — Illustrative and constructed

All case-study material. Nkechi and Owen, the maltings, the seven-piece band and its floor counts; the Reyes–Whitfield music plan, Trey Bankole, and the eleven announcements. Constructed.

Case Study 22.1's floor counts are modelled from §22.7's mechanisms rather than observed, and the case says so in its own discussion question 4 — "roughly doubled" is a stacked estimate and every layer of it is soft. It is offered as an argument about direction, not magnitude.

All prices are plausible for a mid-market North American market in the mid-2020s and will be wrong for yours.

Where to go next

Count a dance floor (exercise C.1). Every five minutes, for two hours, with a note on what happened at each inflection. One evening, and §22.7 stops being something you have read.

Ask a DJ the question (exercise C.2): "talk me through a night where the floor didn't fill." Note whether the answer is a diagnosis or a song title — and if it is a diagnosis, ask what they wish the planner had done.

Read Granovetter's threshold paper. It is from 1978, it is about riots and strikes and not about weddings, and it is the best thing available on why eleven people getting up at 8:47 is the whole event.

Establish your market's music licensing (exercise E.2) once, properly. It is a question you will be asked and currently cannot answer.

And read one band's rider carefully, all of it, including the stage plan and the input list. You will discover what a five-piece actually needs, and it is more than anyone told the couple.

Chapter 23 preview

Photography and videography — the other vendor inside every moment of the day, and the one whose requirements most often collide with everybody else's.

Bring §22.7's field note. A photographer needed four minutes at 8:52 and it cost forty minutes of dance floor. The fix is "not then," and it is a line agreed in month six rather than a negotiation at 10:03 between tired people.

And bring Chapter 21's photography restrictions, obtained in writing and still in nobody's contract.
