Sing in harmony
with the people you love.

No music training required. Just your voice and a song.

Connecting voices across living rooms — and across the world. 🌍

HarmonyAlong listens to you sing any song and instantly creates beautiful harmony parts — two, three, four, or five voices — that you and the people you love can learn and sing together. Toggle each part on and off, practice yours alone, then bring everyone in.

How It Works

From humming a tune
to singing in harmony

Three simple steps. No music theory. No sheet music. Just sing.

01
🎤
Sing your song
Hold up your phone and sing any song you love — a classic, a lullaby, a pop hit, anything. HarmonyAlong listens and understands your melody.
02
🎵
Choose your parts
Pick how many voices you want — two parts for a duet, three for a trio, up to five for a full ensemble. The app creates each harmony part automatically.
03
🎶
Learn & sing together
Toggle each part on and off. Practice your part alone first, then bring in the others. When everyone's ready — sing it together.

Music gives a soul to the universe, wings to the mind, flight to the imagination, and life to everything.

The Bigger Picture

Music has no borders.

A family in Lagos. A couple in Seoul. Friends in São Paulo. A grandmother in Naples. HarmonyAlong believes music is the one language every human being already speaks — and we're building the place where those voices come together.

🌍
Sing Across Borders
Share your melody with someone on the other side of the world. Let them add their harmony. Music becomes the bridge between cultures, languages, and generations.
🎙️
