Learn while you create

You don’t need to be a theory expert. Horucco helps you make sense of chords, scales, modes, and progressions as you use them — with an AI teacher that explains what’s happening in your progression.

A faster harmony workflow (especially if you live in a DAW)

DAWs are amazing for production, but they’re not built to explore harmony. Horucco helps you find interesting chord movement quickly: detect chords from songs, transpose, reharmonize, and try substitutions without breaking your flow.

On the go or in the studio

Capture ideas anywhere. Use the mic chord recognition to grab progressions from what you’re listening to, then shape them into your own song with instruments, patterns, and export when you’re ready.

Our Core Features

Real-time chord recognition

Play any song and Horucco listens through your microphone to detect the chords instantly.

Chords you can see and play

Keyboard + guitar fretboard always on screen, so every chord is immediately playable and understandable.

Full edit control (transpose + reharmonize)

Transpose to any key, swap chord qualities, try extensions/voicings, and experiment with substitutions/borrowed chords.

AI teacher (learn, don’t copy)

Get clear explanations of why a progression works (function, cadences, tension/release) — built for learning and songwriting

Next-chord suggestions

When you’re stuck, Horucco suggests musically plausible next chords (trained on thousands of songs) — you choose what fits your idea.

Turn chords into a demo + export

Pick instruments and musician-style patterns to sketch a track fast, then export MIDI or WAV for individual parts or the full project.
