Hello You.

Last week we felt a sound we couldn't hear. This week it's the opposite. The sound you can't stop shouting.

Some of the most quoted lines in rap aren't lyrics. They're a "yeah". A "skrrt". A grunt. A noise in the background that somehow ends up being the whole thing.

So let's talk about ad-libs.

What even is an ad-lib?

The little voice around the bars. Usually recorded as a separate take and tucked behind the main vocal.

It does one of two jobs. Punctuation, landing on the end of a bar like a full stop. Or a second character, the rapper hyping themselves up, agreeing with themselves, laughing at their own line (we've all done it).

How do they make it sound like that? Mostly in the mix. Ad-libs usually sit quieter than the main vocal and get pushed off to the left or right, sometimes bouncing between the two like someone answering from across the room. Then they get their own effects: an echo, a bit of extra space, or the "telephone" trick, where the lows and highs get cut so it sounds like it is coming through an old phone. All of it so they land as a second voice, not the rapper talking over themselves.

"MUSTAAAAAARD"
"MUSTAAAAAARD"

Where it started

Church first. Call and response, a preacher says it, the room says it back. That's the starting point, the blueprint.

Then James Brown took it to the stage. "Good God!" "Hit me!" Grunts, screams, the band answering him. Hip-hop producers like the Bomb Squad and Marley Marl later built whole beats from those bits of Brown, ad-libs included. George Clinton even said people didn't really get "good God" until rap started sampling it.

The hype man moved in

Early hip-hop had a job for this: the hype man. A second voice on stage whose only role was keeping the energy up. Cowboy did it for Grandmaster Flash and the Furious Five. Flavor Flav did it for Public Enemy, "Yeah boyeee!" and a clock round his neck.

Then the hype man moved inside the record. The rapper became their own hype man. These beautiful little nothings pepper through the music, and we love it.

When it took over

The 2000s turned it into a signature. Lil Jon's "YEAH!" and "OKAY!" were basically their own instrument. Jeezy's gravelly "YEAHHH!" and that laugh. Rick Ross's "Hunhh". Gucci Mane's "Burr", so you know exactly how icy he is.

Then 2013. Migos put VERSACE out, Drake jumped on the remix, and suddenly everyone was doing the triplet flow and the Migos ad-libs that came with it. Travis Scott ended nearly every bar with "It's lit!" 21 Savage says "21" on repeat on 7 MIN FREESTYLE. Playboi Carti's DIE LIT is so stuffed with "what?!" and baby voice that the ad-libs almost are the song. Megan Thee Stallion made "Ah!" her own, and Cardi B tried to trademark "Okurrr". The trademark office said no, it was just another way of saying okay.

The UK does it loud too

Grime is a crowd sport. Bars matter, but so does the bit everyone can shout back, and the ad-lib is that bit.

D Double E is the king of it. "Bluku bluku", "oowah oowah", "bud-a-bup-bup". He can get a reaction out of a room with one syllable. He named an EP and his label after one of them, and IKEA put his ad-libs in a Christmas advert. Grime's greatest punctuation mark ended up selling flat-pack furniture.

Lethal Bizzle broke through on lines that were easy to pick up and ad-libs everyone could copy. POW! (FORWARD) is a tune you shout, not one you sing.

Why does it matter?

Because it's the part you remember. You might not know the second verse, you might not catch the rap, you might be too slow, but you know the noise - and there is nothing as good as imitating it in just the right spot.

Maybe you can already hear the image below, and if so - that's what we mean.

It's a name tag. Hear "Burr" and you know who it is before the verse starts. And it's a crowd's way in. Not everyone can rap the bars, everyone can shout "YEAH!" on cue.

The mute test

Your homework this week, should you choose to accept it. Take a song you love and imagine every ad-lib deleted. It doesn't have to be rap or grime, it can be a Hozier yell, a hum, and ooooooo - it all counts.

  • Nothing changes? Decoration, boring, adds nix.

  • The song goes flat? Load-bearing: without it, the song wouldn't be what it is.

  • You remember the ad-lib better than the lyric? It's the hook, and that's the point.

Harder version: can you name the rapper from the ad-lib alone? If yes, that's a signature.

A short, incomplete, list

D Double E, obviously. Flavor Flav. Lil Jon. Jeezy. Gucci Mane. Rick Ross. 2 Chainz and "Truuu". Busta Rhymes, "Woo hah!!". Migos. Travis Scott. 21 Savage. Playboi Carti. Lethal Bizzle. Young Thug, "Slatt".

The one we didn't have room for: producer tags. "If Young Metro don't trust you..." and "Mustard on the beat, ho!" Although Kendrick already broke the wall between the two. On TV OFF the beat switches, the tag plays, and he screams "MUSTAAAARD" at his own producer. The internet lost it the day GNX dropped, and Heinz put it on a billboard. A producer tag turned into an ad-lib, turned into a condiment ad. And maybe, ad-libs are the sauce on the side of the main meal... or something.

And as usual, playlist awaits you.

See you next Thursday.
