Chord Player: Song Builder

Chord Player turns chord progressions into songs you can hear. Write the chords, pick a rhythm, and a band of drums, bass, piano, guitar and synth plays them back, like a keyboard's accompaniment. No account needed, and it works offline except for the song catalogue.

For songwriters sketching an idea, musicians practicing a progression, producers looking for a starting point, and students hearing how harmony works.

🎵 BUILD A SONG, SECTION BY SECTION
• Intro, verse, chorus, ending: every section holds its own chords, repeats and loop
• 39 chord types, slash bass notes (C/E) and half-beat chords
• Piano and guitar diagrams for every chord
• Drag chords to reorder them, or select several at once
• Change the key of the whole song, or move it up and down by semitones

🥁 545 RHYTHMS, LIKE A KEYBOARD
• 545 rhythms in one list, searchable and by genre: from Reggaeton, Salsa, Bachata, Merengue, Bolero and Norteño to Bossa Nova, Afrobeat, Trap, Modern Worship, Funk and Jazz
• Intro, variation A, variation B and an ending: nearly every rhythm comes with them, you can write your own for any, and each section picks its part
• A Fill button to throw in a drum fill whenever you like, and fills on the way from one part to the next
• A twelve-piece drum kit plus twelve hand-percussion rows (congas, bongos, timbales, claves, güiro…), with 16 kits: acoustic, electronic, 808/909, jazz, brushes and orchestra
• Play in 4/4, 3/4, 6/8 or 5/4, straight, with a light swing or a shuffle
• Star your favourite rhythms, sounds and songs
• Keeps playing with the screen off, with controls in the notification

🎛️ MAKE THE GROOVE YOURS
• Edit drums, bass, piano, guitar and synth on a step grid, bar by bar, with the fill on its own
• A pattern strip to try things by ear: your own, the style's variations and ready-made figures
• Each part sounds its own way: the chorus can bring in strings while the verse keeps the piano
• Edit a part once and it changes in every section that plays it
• A keyboard shows each instrument's range, and the drums can be played with your fingers
• 68 recommended sounds and all 261 of the full sound bank, by family: pianos, Rhodes, organs, guitars, basses, pads, strings, brass and more. Tap one and you hear it at once, in the song if it is playing

⏱️ A METRONOME THAT FITS YOU
• Volume, sound (stick, cowbell, ride or beep) and accent
• A one-bar count-in before the song comes in

🎚️ MIX AND EXPORT
• Volume, mute and solo, three-band EQ and compression for each instrument, plus reverb
• Export M4A to share, WAV to keep editing, or MIDI to open the notes in your DAW

💡 START FROM SOMETHING
