Harmony is the secret sauce in most iconic pieces of vocal music. Just listen to the soaring vocal layers in Queen’s “Bohemian Rhapsody” or the tight vocal blend in Boyz II Men’s “Water Runs Dry.” Even more ambient harmony, such as the style found in Bon Iver’s “Holocene,” can add a unique level of dimension to the production aspect of music.
Luckily, understanding basic harmony doesn’t require you to be a professional singer or music theorist. All you need is a foundational understanding of pitch, a little bit of your training, and the right practice routine.
In this guide, we’ll walk you through everything you need to know about how to sing harmony, including what harmony is, how to find the right part, and tried and true exercises and techniques you can use to sharpen your ear.
What is Harmony In Singing?
At its most basic level, harmony refers to two or more different notes sung at the same time. While the melody is the main tune you typically hum or sing along to, harmony adds the extra complexity and depth either below or on top.
Common Types of Vocal Harmony
Part of knowing how to harmonize vocals in a piece of music is assessing what type of harmony you want to use.
Parallel Harmony
Parallel Harmony is when two voices move in the same direction with the same interval spacing. You can hear this in Simon and Garfunkel’s “The Sound of Silence.” Their voices often follow the same melodic shape while staying in consistent intervals apart from one another.
Contrary Motion
In this form, one voice moves up while the other moves down. This type of harmony is great for adding tension and release, and you’ll often hear it in choral music or classical arrangements. You can also hear it in some baroque-inspired pop, like the layered vocals in Imogen Heap’s “Hide and Seek.”
Tight vs. Open Harmony
Tight Harmony usually refers to voices that are close to one another in pitch. You’ll often hear this in jazz and R&B. Boyz II Men has tons of great examples of this in their music.
As for open harmony, that’s when the notes are spread out across a wider range, giving the vocal arrangement a more spacious feel. The style is more common in country, folk, and worship music. Just listen to the chorus harmonies in Hillsong’s “Oceans.”
Best Techniques for Singing Harmony
Now, before we get into complex, layered harmonies, you want to make sure your ears and voice are on the same page. The following techniques can help you build the core skills you need to sing harmony both confidently and accurately.
Match Your Voice to the Melody
Start by singing the melody in unison, so that you can lock in the pitch and rhythm before branching off into harmonies. Listen closely while you do this. Are you centered on the correct pitch? Does your rhythm feel tight?
Being able to sing in tune with somebody else is a foundational skill when learning how to sing harmony.
Learn Your Intervals
Harmony is built on musical intervals, such as thirds, fifths, and sixths. This is where your music theory training comes in. You can use a piano or an app like Tenuto to train your ear. Start by singing along with easy interval jumps and becoming more accustomed to their sound.
Know the Melody Cold
If you don’t know the melody like the back of your hand, you’ll be wandering around trying to find the harmony. Use sheet music or a backing track to drill the main line. Make sure you’ve internalized the phrasing and timing. When the melody is second nature, you’ll have a much more stable anchor for your harmony parts.
Sing Duets
One of the fastest ways to sharpen your skills is by singing harmony with a partner. It also forces you to listen as much as you sing, and do both simultaneously.
Finding Your Harmony Part
Knowing where your voice naturally fits is another part of singing harmony confidently. But how do you figure out what role your voice should play and how to build harmonies around it?
Getting to Know Your Vocal Range
First things first, your vocal range. Whether you’re a soprano, alto, tenor, or bass will determine which harmony parts feel the most comfortable. I recommend using tools like Sing Sharp to find your lowest and highest comfortable notes. The more you know your range, the better you’ll be able to avoid straining notes that sit too far above or below your natural register.
Choose Between Melody and Harmony
Most singers default to the melody. The best way to learn, however, is to practice switching between the main line and the harmony parts.
Try singing a song normally, then a third or fifth above or below the melody. The more flexible you are, the better trained your ear will be to sing in a group or ensemble.
Analyze the Chords
Harmony works best when it supports the underlying chords of a song.
One of my rules of thumb is that the third and fifth scale degrees of a chord are your safest harmony options. Play a triad on a piano and listen to how the third and fifth interact with the root. Actively listening to how a note fits against a chord is the best way to internalize what works and what classes.
Practicing Harmony
In the same way that we practice daily when learning how to sing better, learning to sing harmony takes consistent, focused practice. Let’s take a look at a few strategies and tools you can use to sing and learn how to harmonize more easily.
Start with Simple Songs
The first one might seem obvious, but it’s also something many singers overlook. Start with songs that have straightforward melodies.
“Lean On Me” by the great Bill Withers is an excellent example of a popular song with an instantly recognizable major scale melody. When you’re starting out, avoid jazz standards or complicated classical pieces. Over time, you’ll get to these. Just be patient and get comfortable with the basics.
Use the Right Tools
You’d be surprised how much technology can help speed up the process.
For example, you might try a bone-conduction headset like Forbrain to get real-time auditory feedback and help you track your pitch more accurately.
You can also check out the wide range of singing apps on the market, such as Harmony Helper and Sing Harmonies. These apps walk you through harmony lines and isolate parts, making them easier to hear compared to just listening to a regular mix of a song you like.
Practice Harmonic Exercises
Start incorporating targeted drills into your regular singing routine to practice harmonizing independently.
Beyond the exercise from Sarah Brickel above, some of my favorite harmony drills include:
- Call and Response – Repeat short harmony phrases sung by a track or your teacher.
- Echo Drills – Mimic harmonized phrases on your piano or keyboard.
- Hold-Your-Line Drills – Sing a harmony part while a friend or track sings the melody.
The more you make these exercises part of your routine, the faster you’ll build muscle memory for harmonies.
Practice with Piano or Guitar
…or whatever instrument you play! Just make sure it’s capable of playing harmony. Use simple triads (root-third-fifth) on an instrument to hear how harmony notes sound in context. Sing along with each chord tone individually, then layer them. This will tune your ear to what works harmonically or sounds dissonant.
Advanced Harmony Techniques
Once you’ve mastered the basics, you can start to explore more advanced harmony strategies, such as the ones below.
Three- and Four-Part Harmony
These styles of harmony, which often include soprano, alto, tenor, and bass (SATB), are very popular in choral, worship, and barbershop music.
The point is that each voice part contributes to a different chord tone, which can either be spaced tightly together or spread out, depending on the genre.
Check out the first video in the above series as an introduction to barbershop music.
Harmonizing with Chord Progressions
Understanding how harmony fits within chord progressions is much more useful than just stacking notes and feeling out whether they work or not.
For example, in a common I-IV-V-vi chord progression (e.g., C-F-G-Am), the most consonant or “good-sounding” harmonies often use the third and fifth of each chord. Practice singing one chord tone consistently as the progression changes beneath it, then switch. This exercise will help you internalize harmonic movement.
How to Learn to Harmonize in Different Genres
Different genres call for different styles of harmony. It’s worth exploring all of them to make yourself a more versatile singer.
- Worship Songs – You’ll often hear thirds and sixths in worship music, as they create a more unified sound. Fifths tend to be popular as well, as they offer a stable, sometimes heroic feeling that can act as a lift in powerful worship songs.
- Country – Open intervals like thirds and fifths are popular in country music. You’ll hear these in a lot of Johnny Cash or Dolly Parton songs.
- R&B – This is one of the few popular genres that uses jazzy voicings, blue notes, and suspensions. Think of singers like Erykah Badu or groups like TLC.
I highly recommend exploring harmony-heavy songs in as many genres as you can. Try isolating the parts and seeing what elements of the song’s chords they cover. This will give you a better idea of how to write or sing harmony for similar pieces of music in the future.
How to Avoid Common Harmony Issues
If you’re running into trouble with learning how to sing harmony, it might be one of the following issues.
Pitch Problems
If you’re struggling to sing on-key, you likely haven’t developed your ear training.
One of the best fixes is using musical apps to train your ear. I also recommend recording yourself singing harmony and comparing it to the melody. Sometimes hearing yourself from a different perspective is the best way to suss out your problems.
Timing and Synchronization
Coming in too late or too early is one of the easiest ways to ruin a good Harmony blend.
My favorite fix for this issue is focusing on locking into the lead singer’s rhythm and phrasing. Start by singing along with the melody, then shift into the harmony while maintaining that timing.
Volume Balance
Harmony isn’t supposed to compete with the melody. It’s supposed to support it.
Learn how to harmonize vocals slightly under the volume of the lead. Listen to duet recordings to see how professional singers find that balance.
Overthinking
Trying too hard can disconnect you from what you’re trying to achieve.
If you’re really struggling, step back and listen. Feel out the harmony rather than forcing it. Sometimes, the best harmonies come from instinct and repetition instead of mental math.
How to Use Forbrain to Learn How to Harmonize
As we noted earlier, Forbrain is a bone conduction headset device that offers real-time auditory feedback to help you hear your voice more clearly while singing. It can make pitch discrepancies easier to note and correct, help isolate your harmony line from the melody, and improve vocal blend when singing harmony with a group.
I recommend using it during warm-ups and while practicing melody-to-harmony transitions. Once you feel good about how you sound and where you’re at, remove Forbrain to see how your muscle memory reacts.
Final Thoughts – How to Sing Harmony Like a Pro
Harmony isn’t something you’re born with. Anyone can learn it with the right amount of focus and repetition. Start with simple songs and exercises, and train your ears on one interval at a time.
Throw in tools like Forbrain to help speed up the process! In due time, your harmonies will start to feel as natural as your everyday singing.
FAQs
Is it hard to sing harmony?
Not with regular practice. Start by singing songs in unison, then exploring simple intervals like thirds and fifths. Over time, your ear will get used to recognizing these patterns, and it will become more natural.
How do I find harmonies by ear?
Train your ear by learning intervals and chord theory. The more you practice singing specific intervals and harmonies, the more naturally they’ll come to you in live or studio situations.
How do you sing three-part harmony?
Divide your voice into three parts based on vocal range, such as soprano, alto, and tenor. Each part harmonizes within the chords of the song, typically a third or fifth away from the main melody or root.
