Deps and substitute musicians: a system that never lets a gig down

The bassist has a fever on Thursday and the wedding is on Saturday. In a band with a dep system, this is a 20-minute job: one message to the first name on the list, a link to the charts, done. In a band without one, it is a two-day panic, a player who has never heard your arrangements, and a leader who spends the soundcheck teaching endings.

A dep (substitute musician) is not a contingency; it is part of how a working band operates. Over 40 gigs a year, expect 3–6 to need a dep for some chair. Here is the system.

The dep list: two names per chair

For every position in the band, keep two people who have agreed in principle to dep, ranked. For each: name, phone, email, instruments and whether they sing, distance from your base, rate agreed, and the date of their last gig with you. Six chairs, twelve names.

Where they come from:

• Musicians you have shared bills or stages with and liked.
• Members of other bands in your scene who gig less than you.
• Players your engineer or your members recommend.
• Good candidates from your last audition who did not get the job.

Ask them properly: "We'd like you on our dep list for bass. Local gigs pay 220 €, full-day out-of-town gigs 300 €. We'd send charts, band recordings and a setlist a week ahead. Would that work?" A yes now is worth a lot on a Thursday.

Refresh the list every six months. People move, quit, get busy. A dep list where both names are stale is not a dep list.

Charts that a stranger can play from

The dep system fails if the material lives in the members' heads. For every active song you need:

• The band's key, which is often not the original key. See choosing keys for your singers.
• The band's tempo as a BPM.
• A structure map: intro (4 bars, guitar riff), V1, C, V2, C, bridge, C x2, ending (stop on 1). See song structure notation.
• A chord chart or lead sheet in that key, or Nashville numbers, so that a good player can read it cold. See chord charts, lead sheets and Nashville numbers.
• A band recording, ideally a live one, so that they hear your arrangement rather than the album's.

Test it: give a musician who has never played with you your charts for ten songs and see how much of the rehearsal is spent on things the chart should have told them. Each of those is a chart to fix.

Fee rules

Decide these once and put them in the band agreement, because the moment a dep is needed is not the moment to negotiate.

What the dep is paid. A fixed rate agreed in advance, paid on the night or within a week. Do not pay deps a "share" of an unknown fee; they want a number. Typical ranges in western Europe for function work are 180–300 € per gig depending on length and travel; adjust to your market. Pay slightly above what you think is fair. A dep who is paid well and promptly comes back, and tells other good players about you.

Where the money comes from. Three common rules:

1. The absent member pays the difference. If the dep costs 220 € and the member's share would have been 250 €, the member gets 30 €. Fair when the absence is optional (a holiday, another gig).
2. The band pays. The dep is paid from the fee, the rest is split among those who played, the absent member gets nothing. Fair when the absence is unavoidable (illness, bereavement).
3. Session-rate bands. The dep gets the chair's rate. The leader's margin does not change. Simple.

Most bands use a mix of 1 and 2: illness is the band's cost, choice is the member's. Write it that way.

Who arranges the dep. The absent member finds and briefs the dep from the list, unless they are too ill to do it, in which case the leader does. Either way the leader approves the choice.

Deposits and cancellations. A dep who has said yes is booked. If the member recovers and wants the gig back, the dep is still paid at least half. Deps talk to each other about who cancels on them.

Briefing a dep in one message

The brief should be one message with everything, sent the moment they say yes, so that they can start learning that evening. The template:

Thanks for stepping in on Saturday 14 June. Details: Gig: Kowalski wedding, Villa Rosa, Lindenstraße 4, Bad Homburg. Map: [link]. Times: load-in 16:00, soundcheck 17:00, guests in the room from 18:30, background set 19:00–20:00, party sets 21:00–22:15 and 22:45–00:00. Load-out by 00:45. Line-up: Lena (vocals), Ben (guitar, MD, count-ins), Anna (keys), you (bass), Tom (drums). Ben is your contact on the day: +49 ... Setlist and charts: [link]. Three sets, 38 songs. Keys are our keys, not originals. Band recordings are attached to each song. Priorities: the first dance is "At Last" in F, 62 BPM, with a held ending on Ben's nod. We stop dead before the last chorus of "Valerie". Everything else is on the charts. Gear: we use in-ears; bring your pack and a spare cable, or wedges are available. DI provided. Stage is 6 × 4 m. Dress: black, no logos. Fee: 300 € (full day, 90 km each way), paid by bank transfer on Monday. Parking and a meal are provided. Please confirm you've got the charts open and the recordings play.

Everything the dep needs is in one place, and nothing needs a second message. A version of this brief is also what the band's own members should get; see the day-of-show checklist.

On the night

• Put the dep next to the MD or whoever cues endings. Nods beat shouting.
• Run the first dance and the two trickiest transitions at soundcheck. Not the whole set; the three things that will go wrong.
• Introduce them to the client as part of the band. Nobody needs to know it is their first gig with you.
• Pay them before they leave, or tell them the exact day the transfer lands.

Do this today

• Write the dep list. Put a name in every slot, even if the second name is a guess to confirm next week.
• Send the "would you be on our list?" message to the three people you are least sure about.
• Pick one song and check that its chart, key, tempo and a band recording exist. Then do the next one at each rehearsal.

Where expert.band helps

A dep can be invited to the band free, for one gig if you like, and sees the setlist in order with each song's key, tempo, structure and attached band recording, plus the gig page with times, address, map link, line-up and their packing assignments. Remove them afterwards and their access ends while the gig record stays. The dep list itself is yours to keep wherever you like; expert.band holds the charts and the gig sheet that make the brief a single link.
