Post the song
with the hole
cut in it.

Strangers record inside your actual track. You audition every take blind, pick one by ear, and the equity split signs itself the instant you pick.

🎯One object does five jobs

A hole is the content, the search query, the job post, the contract, and the ad. Nothing else in the app is new.

01 / Cut

You delete your own chorus

Drag two handles across the waveform. The server renders the track with the gap already removed, so the missing part can never be downloaded.

02 / Stake

Every vacancy costs equity

5 to 50 percent of the composition, attached to a one-screen split sheet you sign at posting. Zero-stake holes are structurally impossible.

03 / Fill

The only way to reach anyone

Strangers record inside the gap, in context, three takes max. Submissions are sealed and stripped of identity server-side.

04 / Turn

Take 4 of 11, no names

Every fill plays slotted inside the full song, randomized, unlabeled. Hold to pick. There is no back door to any identity.

05 / Reveal

The contract is a side effect

Names unmask both ways at once, the filler countersigns the half-signed split, and a workroom opens with the stems already loaded.

🔒What is contraband here

Each removal closes a failure mode that killed a predecessor. The absences are the product.

No browsing peopleOnly holes are discoverable. Faces appear after ears decide.
No DMsThe first message anyone can send you is a performance.
No follower countsImported clout is an anti-signal. It never touches a hole or a fill.
No unpaid asksEvery hole carries equity. "Exposure, no points" cannot be posted.
No real-time jammingPhysics won that argument. No premium tier reverses it.
No public rankRejection stays invisible. Releases are private, only picks are public.
No paywall on matchingMoney rides output: distribution, escrow, sponsored House Holes.
No meters or gain slidersNothing in the UI asks a singer to think like an engineer.

⚠️The one thing that can kill it

The mitigation is one rule. It has to hold.

Most unfinished songs are weak, not incomplete

If the board fills with junk holes staking worthless equity, the stake becomes a public price list for garbage and the whole confident design indicts itself.

Earn to post

Nobody cuts a hole until they have filled one, and every post spends a fill. One rule, four jobs:

Throttles supply. Filters posters through the judged side.

Converts oversupplied roles into fillers. Makes onboarding produce real audio.

The weekly House Hole backstops thin weeks.

💡The artifact that leaves the app

1080 × 1920. The left card recruits before Tambr has a second user. The right is the receipt; it flips when someone gets picked.

Tambr Hole Card: 16 bars open, F minor, 20% of this song
BeforeHole CardThe ask, priced. Tap it anywhere and the track plays up to and through the silence.
Tambr Filled Card: the gap now filled, two identity marks overlapping
AfterFilled CardSame layout, gap lit, two marks phase-locked into one. Taste and generosity in a single image.

🎨Chladni, not chrome

Named for the sand figures that appear on a vibrating plate. Warm black, bone, verdigris. Flat 1px hairlines, one corner radius, no shadow anywhere in the app.

Identity is a curve

Two onboarding parameters draw it. It tells no one your gender, age, or city, and phase-locks with your collaborator's at the reveal.

The loop, start to shipped

Onboarding is a recording. You cannot post until you have filled.

01Open the Board

Holes in your role and key range autoplay, and each goes conspicuously silent where you would come in.

02Fill one

Record inside the gap with the track in your ears. Three takes. Submit sealed. You just earned a posting credit.

03The window closes

The poster auditions every fill in full context, blind, by ear only.

04The pick fires

Mutual unmask, countersign, split PDF hashed and stored.

05The workroom opens

Both stems loaded, timestamped comments on the waveform, export gated behind the signed sheet.

06Ship it

The before and after credit mints permanently on both ledgers, with PRO and MLC registration pre-filled.

07Spend the credit

Cut your own hole, stake it, post it, share the Hole Card anywhere.

08Tuesday noon

The House Hole drops for a whole genre division. Fill it, or just listen and vote without an account.
