SongHub Duet Mode: How to Sing Duets and Split Harmonies

Some songs are just better with two voices. Duets turn karaoke from a solo performance into a shared moment, and they are the kindest format for nervous singers: nobody is exposed alone, and the energy doubles. SongHub handles duets beautifully once your audio setup is right. Get the app from the official SongHub download and this guide will take you from one mic to two-part harmony.

There is no hidden duet button to unlock. A duet in SongHub is a combination of the right hardware (two mics into one mix), the right song file, and a little planning about who sings what. Nail those three and your duets will sound like you rehearsed for weeks.

How Duets Work in SongHub

SongHub plays the backing track and lyrics exactly as it does for a solo song. The difference is at the input: two microphones feed into the mix instead of one. Both voices blend over the same music, and the lyrics highlight on screen for both singers to follow. Because SongHub songs are MIDI-based, the backing stays perfectly in tune no matter how you transpose it, which matters a lot when two voices need one shared key.

For songs written as duets, the two vocal parts are often already separated in the arrangement, call and response verses with a joined chorus. For regular songs, you create the duet yourselves by splitting the sections, which is where the real fun starts.

Setting Up Two Microphones

You need both mics audible at the same time. The simplest route is a small mixer: plug both mics into the mixer, plug the mixer into your speaker, and run SongHub audio into the same speaker. A two-channel mixer costs less than most wireless mics and is the single best upgrade for duet singing. See our microphone guide for mic picks that pair well.

If you are using USB mics with a phone, an audio interface with two inputs does the same job digitally. Test the balance before anyone sings: have each person count to five at performance volume and set their level so neither voice buries the other. The quieter singer usually needs a small boost, shy singers pull away from the mic without realizing it.

Splitting Parts Like a Pro

The classic duet split: Singer A takes verse one, Singer B takes verse two, and you sing the chorus together. For call-and-response songs, just follow the original artists. Write the split on a printed songbook page so nobody freezes wondering whose line is next.

Now the key question: whose range wins? Neither. Use the key changer to find a key between your two voices. If one of you sings higher, that singer can take the melody up an octave while the other stays low, the same notes, an octave apart, which always sounds rich and intentional.

Easy Harmonies Anyone Can Sing

Harmony sounds advanced, but the beginner version is simple. One singer holds the main melody exactly as written. The other singer finds a note a third above, usually two or three notes higher on the scale, and follows the melody shape in parallel. When the melody goes up, the harmony goes up; when it comes down, the harmony follows.

Start harmonizing on the chorus only, where the melody is most familiar. The two most forgiving spots are the final chorus repeat and any "ooh" or "ah" backing section. Even a slightly imperfect harmony sounds gorgeous over a MIDI backing because the instruments hold the tuning center for you.

Best Duet Songs to Start With

• Natural duets. Songs written for two voices: "Summer Nights", "A Whole New World", "Don't Go Breaking My Heart", "Shallow". The parts are already divided for you.
• Split verses. Any verse-chorus song works: take turns on verses, join on choruses. "Country Roads" and "Stand By Me" are perfect first attempts.
• Octave duets. One singer high, one singer low on the same melody. Works on nearly any anthem and always sounds bigger than the sum of its parts.

Browse duet-friendly tracks by their songbook numbers so both singers can find the song instantly on the night.

Running Duets at a Party

Duets are a secret weapon for party energy. They pull shy singers in pairs, they break up a long run of solos, and the crowd loves the interaction. Slot a duet every four or five songs in your rotation. Our karaoke party checklist shows how to weave duets into the night's flow so the energy never dips.
