The free beat "Perimetro" from producer Nari is an 86 BPM boom bap instrumental in C# minor, made with DEXTAH, and you can download it for non-profit use if you subscribe to the channel. You can grab the paid, cleared version and the buy-one-get-one deal through the Nari BeatStars store, which is the only place that grants you monetization and Content ID rights.

What Perimetro actually is and why it suits a free beat search

Perimetro is a dark, old-school boom bap type beat built for freestyle rap, with a slow 86 BPM pocket and a minor key that keeps the mood heavy. The title and tags point at the Argentine underground scene around Bardero$ and C.R.O, and the production credits list two people: Nari and DEXTAH. At 86 BPM you get roughly 21 bars in 60 seconds, which is a comfortable tempo for double-time flows and dense internal rhyme schemes without rushing the delivery.

The key of C# minor is a practical detail worth knowing before you write. It sits a half step above C minor, so a standard C minor loop or a vocal take pitched up a semitone will fit, and guitar or piano samples in E major (the relative major) will also work over the top. Producers tag these instrumentals as underground boom bap, dark boom bap, chill rap or freestyle beats, but functionally they are all the same thing: a two-to-four bar loop with a swung drum pattern that leaves room for a voice.

How to use the free version without breaking the license

The free download is a subscriber-only license limited to non-profit use, and it does not cover streaming platforms. That single sentence from the description decides almost everything about how you can release a song on this beat, so read the terms before you upload anything.

1. Subscribe to the Nari channel and download the free tagged or untagged file offered there.
2. Use it on YouTube or SoundCloud only, with monetization turned off on that specific upload.
3. Do not distribute the song to Spotify, Apple Music, Deezer, Tidal or any other streaming service.
4. Do not register the song with Content ID, because that requires an exclusive purchase.
5. Keep a record of the beat name, the producer credits (Nari x DEXTAH) and the date you downloaded it.

If a distributor asks you to confirm you own the instrumental, the free license will not satisfy them. In that case you buy the lease or the exclusive, and the store link in the description is where that happens. Content ID is the part people underestimate: registering a track that contains a leased or free beat can get your whole catalog flagged, and the producer's terms put that risk on the artist.

How to write and record a freestyle over an 86 BPM boom bap beat

At 86 BPM the beat gives you space, so the fastest way in is to record a long take and keep the best 16 bars. Start by looping the first four bars and humming a cadence before you write a single word, because boom bap rewards pocket over syllable count. A simple structure that works: an eight-bar intro with no drums, a 16-bar verse, an eight-bar hook, a second 16, then the hook twice.

Practical steps for the session:

1. Set your DAW tempo to 86 BPM and confirm the grid lines up with the kick, since some free files have a short silence at the start that needs trimming.
2. Record a scratch freestyle take of two to three minutes with no punch-ins, then pick the strongest four-bar blocks.
3. Write the hook last, after you know what the verse is actually about.
4. Double the last word of every fourth bar rather than the whole verse; on a dark boom bap loop, heavy doubling muddies the low mids.
5. Leave the beat's siren-like melodic sample exposed in the intro and let the drums drop in on the first bar of the verse.

For mixing, high-pass your vocal around 80 to 100 Hz, cut a narrow notch where the vocal sounds boxy (usually 200 to 400 Hz), and compress at a 3:1 ratio with a fast attack. A short plate reverb at 15 to 20 percent wet and a quarter-note delay at low level will sit the vocal inside the loop instead of on top of it. Keep the master around -1 dBFS true peak if you plan to upload to YouTube, which normalizes loudness anyway.

Typical questions from rappers picking up a free type beat

Most doubts around free beats are about permission, not music. Artists want to know whether they can monetize a video, whether a distributor will reject the track, and whether the beat is really free or just free to listen to. The honest answer for Perimetro is that the free file is a promotional license for non-profit uploads, and every commercial step, from ads to streaming to Content ID, requires a purchase.

A second cluster of questions is about fit. Rappers writing in Spanish, Portuguese, Italian, Russian or Azerbaijani have all rhymed over this kind of dark, slow boom bap, and the tempo suits Romance languages well because the syllable density per beat stays manageable. If you normally write trap at 140 BPM, expect to rewrite your cadence: at 86 BPM you have roughly 1.7 times more time per bar, so lines that felt full in trap will feel empty here until you add internal rhymes. Some listeners will ask for a trap version of the same mood, which is a different request entirely and usually means a faster tempo and 808-driven low end.

Where to find the beat, the producer and the license

All official links for Perimetro live in one place, and the store link is the one that matters for anything commercial. The beat store carries the lease and exclusive options plus the current promotion, and the social profile is where new drops and free downloads are announced first.

• Paid lease and exclusive purchase, plus the buy-one-get-one offer: https://bsta.rs/jwmVqm
• Producer Instagram for new beats and free downloads: https://www.instagram.com/nariprodd/?hl=es-la
• Full beat catalog: https://prodbynari.beatstars.com/
• Contact for custom work and licensing questions: snewkix666@gmail.com

The promotion structure is straightforward: add two beats to the cart and get one free, add four and get two free, add six and get three free. If you already know you want a small catalog of dark boom bap instrumentals rather than a single track, that math is worth doing before checkout.

Conclusion

Perimetro is a usable, well-built free beat: 86 BPM, C# minor, produced by Nari with DEXTAH, and pitched squarely at underground boom bap and freestyle rap. Treat the free download as a demo license for non-profit YouTube and SoundCloud uploads, and treat everything else, including streaming and Content ID, as a paid permission. Write to the pocket rather than the grid, keep your vocal chain light, and the slow tempo will do most of the work for you. When you are ready to release properly, get the cleared file through the Nari BeatStars store and credit Nari x DEXTAH on every upload; the channel Nari is where the beat and its terms come from, so check the description there before any release.
