A chord player built for hearing progressions, not just listing them
Song ideas often start as four chord names on a sticky note. That is enough to remember the shape, but not enough to judge whether the sequence works at your tempo, in your key, or with the groove you have in mind. This page is a chord player first: you set major or minor, choose a pattern, and listen to the whole strip with piano, drums, and guitar if you want them. When a change is needed, you edit in place—swap a chord, shorten a bar, drag cards into a better order—then play again. The goal is a fast loop between hearing and adjusting, the same way you would noodle on a keyboard without stopping to rewrite a chart.
Playback that reflects real arrangement choices
Each pattern changes how chords are voiced and struck—block chords, arpeggios, bass roots, off-beat hits—not only which letters appear on screen. Pop 1 might keep a steady quarter-note pulse while Pattern 4 leans on backbeats. Switch patterns on the same progression to compare feel before you commit to a demo idea. Loop playback when you want to walk around the room and listen for weak transitions.
- Eleven accompaniment styles: Pop 1–3, Rock, and Pattern 1–7 each shape rhythm and voicing differently on the same chord strip.
- Shareable links restore your exact setup—key, mode, tempo, pattern, instrument mix, and every chord with its beat length—so collaborators open the same sketch.
- Accompaniment panel: turn piano, drums, and guitar on or off to hear how much harmonic support a progression needs.
- Editable timeline: click a chord to change quality or root, resize beats per card, long-press to reorder, or add new chords from the + slot.
- Works in any common key with diatonic suggestions while editing, which helps when you are testing substitutions without leaving the scale.
- Built-in audio visualizer at the bottom reacts to playback, useful when you are checking balance between instruments on laptop speakers.
- Runs in the browser with the same piano samples used on our online piano—no install, no account, no DAW required for a first listen.
How to use this chord progression generator
Set key, tempo, and pattern
Pick your root note and major or minor mode first. That defines which chords are offered as quick replacements when you edit. Set BPM to match the song section you are sketching—slow for ballad checks, faster for chorus energy. Then choose a pattern from the dropdown. Pop options tend toward straightforward pop/Rock phrasing; Pattern 1–7 lean into ballad, hip-hop, disco, reggae, jazz, blues, and classical-style piano figures. If you are unsure, start with Pop 1 and switch later—the chord names can stay put while the groove changes.
Generate a progression or build your own
Press Generate progression for a diatonic sequence in the current key, useful when you want a conventional starting point like I–V–vi–IV. Prefer your own idea? Click + to append a chord, or tap any existing card to rewrite it. Each block shows beat markers along the bottom; four markers usually means one bar in 4/4. Drag the right edge of a card to shorten or lengthen how long that harmony sits before the next change. This is handy when you want a two-beat passing chord or a held tonic for an extra measure.
Play, loop, and tune the arrangement
Hit Play or press Spacebar to hear the strip from the top. Active chords highlight as beats advance, so you can spot where a change feels rushed or late. Use the loop button when you want continuous playback while you hum a melody or test lyric phrasing over the harmony. Open Accompaniment to mute drums for a stripped verse, add guitar for a fuller chorus, or run piano alone when you are focused on voice leading. The visualizer under the action buttons shows live output—helpful on quiet speakers.
Share a finished sketch
When the progression is worth sending to a co-writer, bandmate, or student, press Share. The page copies a URL that encodes your current state. Anyone who opens it lands on the same chords, tempo, pattern, and instrument toggles. Nothing is stored on our servers; the link simply packs your settings into the address. For classroom use, that means one click from teacher demo to student practice. For songwriting, it beats pasting chord letters into a chat and hoping everyone imagines the same rhythm.
Where a browser-based chord player earns its keep
People reach for this tool when they need to hear harmony quickly—before opening a DAW, before booking rehearsal time, or before committing lyrics to a progression that might not survive the first playthrough.
"The result explained the difference between my extreme notes and my comfortable range. That’s exactly what I needed."

"I use it in lessons when a student brings a melody but no chords. We generate something in their key, play it once, then swap one chord at a time until the line sits right. Sharing the link means they practice the same version at home."

"Our worship team posts a Pattern 3 link in the group chat Wednesday night. By Sunday everyone has heard the same groove, not just the same letters on a chart."

"I write bedroom pop on headphones. Looping a four-chord strip with drums muted helps me decide if a pre-chorus lift is worth keeping before I record anything."
