See Your Voice on the Song, Then Challenge Your Friends

Until now, a HumMatch score was a number. You hummed, we measured, and we told you how well a song fit your voice. Today the number gets a picture, and the picture gets a social layer.

Two things ship together: vocal overlays on every song page, and the Hum Challenge. Here is what each one does and why they belong together.

Your range, drawn on the song

After you hum your three notes at /try, every song page on HumMatch changes. Instead of a score floating on its own, the page draws your measured range on a piano keyboard, directly against the song's range. You can see, key by key, where the song sits inside your voice, where it leaves your comfort zone, and where it asks for notes you do not have.

Next to the keyboard sits a fit meter and a plain verdict. Not a chart you have to interpret. A sentence that tells you whether this song is yours.

Your voice on this song

YOUR FIT45%

This is the same measured data the matching engine has always used. The difference is that now you can see the reasoning. When the verdict says a song fits, the keyboard shows you why. When it says a song is a stretch, the keyboard shows you exactly which notes are doing the stretching.

The Hum Challenge: make it personal

Once you can see your own voice on a song, the obvious next question is: what does my friend's voice look like on it?

So every song page now has a challenge button. You can send it three ways: your phone's share sheet, a copied link, or up to 3 emails at once. The link carries your range with it, which means your friend does not receive a generic invite. They receive your voice, drawn on a song, with an implicit question attached: can you sing this one?

When your friend hums, they decide whether to share their result. Sharing sends their first name and their range, nothing else. If they opt in, both of you land on a shared squad card: every consented range stacked on one keyboard, the zone you share highlighted, and a group score against the song. The card is labeled DUET at two voices, TRIO at three, and QUARTET as it grows.

The squad card answers a question that used to take a full karaoke night to figure out: which songs can this specific group of people actually sing together? Now it takes one link and thirty seconds of humming per person.

What challenges earn you now

Updated July 18, 2026: this launch originally rewarded challenges with extra free hums. HumMatch has since become a music discovery search engine built on your Vocal ID, and referral rewards moved with it. Each earned-and-unused bonus hum converted into a banked Discovery Day. And as of July 26, 2026, humming is unlimited for everyone, free forever, so hums no longer need rewarding at all.

When a friend creates their Vocal ID through your challenge link, you earn two things, permanently tracked in My HQ:

A Discovery Day: 24 hours of unlimited voice-ranked search with every result scored, the Squad Leader search experience. Credits bank up and activate automatically the next time you hit the daily scored-search limit.

A vault slot: your saved-song cap permanently grows by one, from the base 5 up to 15 total.

Each friend counts once, when their Vocal ID is created, so the rewards follow real new voices, not repeat clicks.

The monthly contest: a free year of Squad Leader

There is also a bigger prize. Each calendar month, whoever brings the most friends who create a Vocal ID through their link wins a free year of Squad Leader, the $59.95/year plan. One winner each month. Each friend counts once, ever, so the leaderboard rewards reach, not refresh clicks.

Track it all in My HQ

Everything about your challenge lives in My HQ: your friend hums this month, the current contest leader, your challenge link ready to copy, and a "My hummers" list of everyone who shared a result with you. That last list quietly becomes something useful: a roster of friends whose ranges you already know, which is exactly what you want the next time someone suggests karaoke.

Why we built it this way

HumMatch has always measured one voice at a time. But singing is rarely a solo activity, and the most common thing people did with their results was show them to someone else. The Hum Challenge just closes that loop: the showing now produces data, the data produces a shared card, and the card produces a plan for the next time your group is in front of a microphone.

Hum your notes, open a song, and look at the keyboard. Then send it to the friend you most want to out-sing.
