OR BRING YOUR OWN MUSIC

For tab audio, choose the tab playing your music and enable “Share audio.” Supported desktop browsers replay it here with a short delay so the count stays ahead.

LESS CLICKING. MORE GROOVING.

Meet your shortcuts.

Use these while you're in the studio. Shortcuts pause when you're typing or choosing an option.

Space
Your keyboard is a tap pad.

In Practice or Test, press once on every beat. J and F work too.

FIND YOUR COMFORT ZONE

A few fine adjustments.

Enhanced uses a larger beat detector for loaded songs. It downloads 83 MB once and takes longer; real-song accuracy is still being evaluated. Applies to the next song you load.

not calibrated

Optional fine-tuning. Speaker/headphone delay is compensated automatically; calibration measures only your input's lag (keyboard ≈ 10–30 ms, touch ≈ 20–60 ms) plus any personal early/late bias, and subtracts it from your taps. Redo it after changing input device.

Find your natural timing.

You’ll hear 16 steady clicks. Don’t react to each click — settle into the rhythm and tap along with the pulse, the way you’d tap to music. Use the input you normally practice with (screen, spacebar, or back-tap).

Reacting instead of anticipating adds ~200 ms that isn’t there when you dance, which would skew your scores late. The first two clicks are ignored while you find the pulse.

YOU ALREADY HAVE RHYTHM

Let's help you find it.

Start small. One song, a few minutes, and a little room to get it wrong.

01

Listen before you tap.

Choose a song or try a sample. Press play, watch the count, and listen for the steady pulse underneath the melody. Turn on the metronome click if you need a hand.

02

Find the beat with your hands.

Choose Practice and tap the pad or press Space on each beat. The timing meter shows early, on time, or late. Aim for a comfortable, consistent rhythm.

03

Check in with yourself.

Choose Test yourself . Your first tap starts a session; your timing feedback stays hidden. Tap for a few bars, then choose Finish or hold Space for 1.5 seconds to see your report.

About the name

“Rhythm Is All You Need” is a little AI joke: a nod to Attention Is All You Need, the 2017 paper by Vaswani and colleagues that introduced the Transformer. Here, we're paying attention to the beat.

Why count to eight?

Much of the music we dance to has four beats in a bar. Two bars make an 8-count cycle: 1, 2, 3, 4, 5, 6, 7, 8. Listening for the “1” helps you hear where musical ideas begin. Songs can add or drop beats, so trust your ears as well as the count.

What about six-count dance patterns?

The music keeps its 8-count while a six-count dance pattern repeats over it. Choose 6-count to practice that pattern. The smaller number underneath keeps track of the music's count.

The count feels off. What can I do?

Turn on the click track and listen. If it matches the pulse but the “1” feels wrong, use Adjust the count . Use ±4 to swap 1 and 5, or tap This is 1 on the beat you hear as the start. Quiet intros, live drummers, and tempo changes can make detection harder.

How do live microphone and tab audio work?

Microphone mode listens to music playing around you. For browser audio, share the tab playing music and enable “Share audio.” Where supported, we replay it with about 15 seconds of delay so analysis can stay ahead. Pause and restart microphone audio in its original source.

Give live mode a few seconds to find the pulse. When the music stops or changes, the app listens again.

Reading the waveform and your report

The music scrolls beneath a fixed playhead. Listen shows every beat number: a blue “1” starts the 8-count, and pale blue numbers show the rest. Numbers gently pulse as they reach the playhead. Practice and Test hide the live counter. Practice hides beat lines and upcoming counts; each number appears in an orb above the waveform when you reach it. The “1” is blue; other counts are pale blue. Diamond markers show your taps: green for on time, amber or red for off-beat. Hover over a marker for its time and details. Drag or flick the waveform to move through the song, or use the progress bar along its bottom edge. Test hides all beat and tap markers. Your report covers accuracy, consistency, missed beats, and whether your timing drifts early or late.

Does my music leave my device?

No. Audio analysis happens in your browser. You don't need an account, and your songs are never uploaded.
