Chorda: Chords from Any Song

Heard a song and want to play it now? Paste the link, wait a few seconds, and the chord chart shows
up in sync with the audio.

Chorda listens to the song and writes the chart for you: chords in time, a diagram for the chord
playing right now, and a bar-by-bar timeline.

HOW IT WORKS

1. Search the song on YouTube or upload your own audio
2. Transcription runs in the background and we notify you when it is ready
3. Play along while the chart moves with the music

IN THE PLAYER

• Chords synced to the audio, bar by bar
• Diagram of the chord playing right now
• Key change and capo, so the song fits your voice
• Section loop and speed control for the hard part
• Chord simplification when the original voicing is too much
• Alternate versions of the same song

AI HARMONIC ANALYSIS

Not just a list of chords. Chorda shows each chord's function inside the key — tonic, dominant,
preparation — with the exact moment of every change, plus suggested key and chords. That is the
difference between repeating a chart and understanding why it works.

FIX IT AND KEEP IT

• Adjust chords and bars, then save your own reading of the song
• Download the chord chart as PDF or PNG to study away from the screen (paid plans)
• Build setlists, share them by link, and favorite what you are working on

PRACTICE TOOLS

• Microphone tuner, with targets per string and per instrument
• Metronome with pulse, time signature and accents
• Chord dictionary for guitar, ukulele, cavaquinho and piano, with variations
• Learning mode: the song split into short sections, looped at a slower speed, with a checkpoint
before you move on

SOMETHING TO PLAY RIGHT AWAY

The home screen opens with shelves by genre — Brazilian country, MPB, gospel and more — ready to
extract.

WHO IT IS FOR

• Beginners who want to play the whole song today
• Players who need a reliable chart, in the right key
