Fredon finds the chord.
Sing, hum or whistle: Fredon picks up every note and shows you the chord to play, fingers and all.

Sing or whistle a note
—
The chord shows up from the very first note.
Demo: a synth voice hums Ode to Joy, then whistles it. Fredon listens to it just the way it will listen to you.
Sing the whole tune. Fredon writes the chords.
Record a melody or import an audio file. Fredon transcribes it, finds the key and gives every note a chord to sit on. Play them in a row and you hear the tune.
-
Record
Up to 60 seconds of singing or whistling. A count-in and a click in your headphones are there if you want them.
-
Fix
Every note shows up on a piano roll. If one wavers between two half steps, it's flagged and you nudge it with a swipe.
-
Harmonize
One chord per note, picked so the progression flows and phrases land. A different harmonization is one tap away.
-
Play
A chord chart with diagrams for each phrase, a suggested capo, playback, and export to PDF, MIDI or image.
Play a chord. Fredon names it.
Live hears chords too. It recognizes what you play, adds it to your chart, and when you're practicing a specific chord, it tells you which note is missing or which one doesn't belong.
Your instrument, your tuning.
Shapes adapt to the instrument you pick: the open chords everyone learns first, E- and A-shape barre chords, then anything one hand can hold with four fingers.
Everything else in the toolbox.
- Tuner
- Tune string by string on a drawn headstock, one tap away from Live.

Your voice never leaves your phone.
Everything happens on the device: no audio ever leaves it, and sound is only kept if you record a melody yourself, on your phone.
This page works the same way: sound is analyzed in your browser and sent nowhere.
Coming soon to iPhone and Android.
Guitar, ukulele, bass, mandolin, banjo or piano: you sing, it finds the chord.
