On a Samsung Galaxy phone, the quickest route to an original rap beat is to generate a complete instrumental in Soundverse AI Beat Maker or InsMelo AI Beat Maker, export stems or MIDI, then tighten the drum parts and arrangement in a mobile or browser-based editor. Use a prompt that specifies the rap groove, tempo range, drum emphasis, bass movement and song sections, then edit every part before recording vocals.
What A Rap Beat Prompt Needs
Rap production depends on a strong kick-and-snare pocket, a bass part that leaves room for the vocal, repeatable hi-hat motion and clear sections for verses and hooks. Put those decisions in the first prompt instead of asking for a vague “hip-hop beat.”
General shopping ads
- Style: name the rap direction you want, such as boom bap, trap or drill.
- Feel: describe the mood and whether the groove should feel straight, swung, sparse or aggressive.
- Rhythm: ask for prominent kick, snare and hi-hat parts, with space between drum hits for a rapper.
- Low end: request a controlled bassline that follows the kick without masking it.
- Structure: specify an intro, verse, hook, second verse and outro, and ask for transitions between sections.
Step 1: Generate The First Instrumental On Your Galaxy
Soundverse AI Beat Maker
Open Soundverse AI Beat Maker in its web app or Android app. It generates complete instrumentals with drums, basslines, melodies and arrangements, and can export WAV mixes, separated stems and MIDI. Its Free Tier starts with 1,000 tokens upon signup; the Creator & Pro plan lists unlimited generations, studio multitrack access, stem export and commercial licenses.
Try this prompt: “Dark trap rap instrumental, sparse minor-key melody, heavy kick and snare pocket, rolling hi-hats, controlled sub bass, eight-bar verse, eight-bar hook, short intro and clean outro, leave space for a lead vocal.” Generate several versions, keep the one with the clearest vocal space, and export stems so you can adjust drums, bass and melody separately.

- 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
- 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
- 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
- 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
- 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)
InsMelo AI Beat Maker
Use InsMelo AI Beat Maker when you want text controls for genre, BPM, mood and structure. It can generate beats, extend them, separate tracks and export MP3, WAV, MIDI and separate stems. The Free plan lists 3.9 credits; its Pro plan lists WAV download, MIDI export and advanced remix features.
Prompt example: “Boom-bap rap beat at a deliberate tempo, dusty drum character, punchy kick, crisp snare, restrained bassline, chopped-sounding melodic loop, 4-bar intro, 16-bar verse, 8-bar hook, 16-bar verse and 4-bar outro.” Export MIDI if you want to change note timing later, or stems if you mainly need a different drum balance.

- SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
- HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
- BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
- COMPATIBILITY — Works with all devices that have a USB-C port.
- INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.
Step 2: Shape The Arrangement In A Browser Workspace
Beat Shaper
Beat Shaper runs in a web browser and provides editable drums, basslines, synths, loops and arrangements. Its piano roll includes controls for genre, mood, energy and syncopation, with MIDI, WAV, MP3, stem and DAW project export options. The Starter plan lists 32 MIDI clips; the Creator plan is €9 per month with unlimited generations, MIDI, MP3 and WAV downloads, unlimited song lengths and commercial usage rights.
Import or recreate your chosen idea, then use the piano roll to shorten busy hi-hat runs under the rap vocal and reduce melodic notes during the verse. Starter downloads are limited to MP3 and non-commercial use. Ableton Live project export and real-time MIDI require the Producer plan, so check the current plan details before depending on either workflow.

Step 3: Regenerate Or Edit The Drum Pocket
Veena Studio AI Drum Generator
Open Veena Studio AI Drum Generator in your Galaxy browser when the generated drums need more impact. It creates multi-layer kick, snare, hi-hat, tom and percussion patterns, exposes MIDI lanes with velocity and humanization controls, extends patterns into song sections, and exports WAV or MP3. The Basic plan has limited daily requests; Pro is listed at $20 per month with 20,000 credits.
Generate a verse groove first, then make a hook variation by increasing percussion density or changing the hi-hat pattern. Edit velocity so the main snare accents remain clear, and use humanization sparingly so the groove stays tight enough for rap delivery.

DAWG
DAWG is a free cross-platform option that runs on Android and includes nine built-in instruments, sequencing, arrangement, mixing, sampling, MIDI and WAV export. It has no subscriptions, in-app purchases or paywalls, but it is an early-access beta and does not support plug-ins.
Use DAWG to place your exported MIDI or samples into verse and hook scenes, balance the bass against the kick, and export a WAV reference. Its self-contained workflow suits a phone session when you do not need external plug-ins.
Step 5: Check The Beat Before Recording
- Play the instrumental on headphones and the Galaxy speaker to find bass or snare details that disappear on one system.
- Mute the melody for a verse and confirm that the drums and bass still provide a complete pocket.
- Leave a short count-in and an obvious change before each hook so the rapper can enter confidently.
- Export a WAV reference and a version with stems or MIDI retained for later revisions.
Rights And Responsible Use
Commercial permissions differ by product and plan. Soundverse lists commercial licenses for Creator & Pro, and Beat Shaper lists commercial usage rights for Creator; InsMelo says commercial rights depend on its subscription or license terms. The other tools listed here do not establish a commercial license in the supplied details, so check each vendor’s current terms before releasing or monetizing a beat.
Use only voices, samples and recordings you have permission to use. If you imitate a real rapper’s voice, use that person’s consent and follow the platform’s rules; check the vendor terms for covers, samples and generated audio before publication.
