Frequently Asked Questions

It is a free browser game for practicing the end of a rap line on a four-beat bar. The game supplies a beat and rhyme words; you make up the words that lead into each prompt. The ball shows when the fourth-beat rhyme cue arrives.

Choose a beat and word collection, then press Play on the home-page stage. Two blank bars let you hear the pulse before the first prompt. Say the highlighted word as the ball reaches the fourth beat of its bar.

No. Start by saying only the displayed words on beat four. Once that feels comfortable, add a short phrase before each word. The beginner guide shows an eight-bar progression from single words to complete lines.

They are round lengths, and every bar contains four beats. Eight bars are a good first run because you can repeat the same drill quickly. Longer rounds give you more time to develop a flow but ask you to stay on beat for longer.

They change the order of rhyme sounds. AABB uses one sound for two bars, then another for two; ABAB alternates between two sounds; AAAA stays with one sound for four bars. The end words still arrive on beat four.

For an easier start, use Afterglow at 86 BPM, eight bars and full-word hints. When ready, choose a faster built-in beat, hide part or all of each word, or switch from AABB to ABAB. These settings change the drill without requiring an account.

The stars estimate fourth-beat timing, from zero to five. With microphone access, the game counts bars where your voice starts near the fourth-beat cue and converts that count into a rating. It is a practice signal, not a judgment of your whole performance.

No. The microphone does not transcribe your speech or check the prompted word. It also cannot judge rhyme quality, lyric content, flow or pronunciation. A correct-looking star score only means the timing detector heard starts near its target cue.

Yes. Turn Mic timing feedback off before pressing Play, or decline your browser permission request. The beat, prompts, pause control and result screen still work; the result will say that timing was not scored.

The detector looks for a new voice onset near beat four, not for any sound during the bar. Speaking continuously into the cue, low volume or background audio may prevent a hit. Try a quiet room and headphones; use the stars as approximate feedback rather than proof that every word landed correctly.

Yes. Add music accepts an audio file from your device or a public YouTube or SoundCloud link. For a linked track, enter or tap its BPM, start the embedded player and then press Play on the game stage. External playback can drift from the game cue, so built-in or local audio is more reliable for timing practice.

No. The first version asks you to enter BPM or use Tap the beat. It does not analyze the linked track or find its intro automatically. You can set a start time for the embedded player.

Yes. In Add word group, paste at least two lines with four rhyming English words on each line. Each line becomes a sound family in a local collection. You can also search the rhyme finder and send one matching family directly to an AAAA practice round.

It groups North American English pronunciations by their ending sound using the CMU Pronouncing Dictionary. For example, light and night share an ending sound even though their first sounds differ. Names, slang, regional pronunciations and near rhymes may be absent from an exact-match result.

Yes, after a round with a built-in beat and built-in word list. Copy challenge link gives your friend the same beat, collection, bar count, hints, pattern and word order. You compare results yourselves; there is no account, shared scoreboard or independently verified score.

No. Challenge links currently support only built-in beats and word lists. A local file, linked track or custom rhyme family is not included in the URL. You can still copy the result text, but it does not transfer the custom audio or words.

No. Microphone audio is processed in your browser to estimate speaking time. The game does not record, save or upload your voice. Your chosen settings and practice totals may be stored locally on this device.

No. The game runs in a current phone or desktop browser without an app download or sign-up. Microphone feedback requires browser permission, and browser features can vary by device.
