Scat singing is a form of vocal improvisation in jazz where the singer uses wordless vocables, nonsense syllables, and sounds like “shoo-bee-doo-wop” instead of traditional lyrics. Rather than telling a story with words, the vocalist treats their voice as an instrument, weaving spontaneous melodies that mirror the phrasing and agility of a horn player.
If you’ve ever heard Ella Fitzgerald scat her way through a fast swing number or watched Louis Armstrong trade phrases with a trumpet, you’ve already met scat singing. It is one of the most thrilling, expressive techniques in jazz, and it has a surprisingly rich history.
This guide walks through what scat singing is, where it came from, who shaped it, and how to start trying it yourself. Whether you’re a curious listener or a vocalist looking to add improvisation to your toolkit, you’ll find practical, beginner-friendly answers here.

What is Scat Singing?
Scat singing is vocal improvisation with wordless syllables. The singer abandons written lyrics and instead invents melodic lines on the spot using vocables, onomatopoeia, and rhythmic sounds. The result feels more like a trumpet or saxophone solo than a song with a story.
The technique lives at the heart of jazz singing because it borrows directly from instrumental tradition. A good scat solo follows chord progressions, plays with swing feel, and responds to the band in real time. The voice essentially becomes another horn in the ensemble.
What makes scat singing distinctive is the syllable choice. Singers pick consonants and vowels that shape articulation, much like a trumpet player shapes notes with the tongue and breath. Sharp syllables like “da,” “ba,” and “shoo” create punchy, percussive phrasing, while rounder sounds like “doo” and “wah” glide more smoothly through a phrase.
There are no fixed words to memorize. Every scat solo is improvised, which means no two performances are ever quite the same. That spontaneity is exactly what listeners love about it.
Scat Singing vs Vocalese: What’s the Difference?
People often confuse scat singing with vocalese, but they are not the same thing. Scat singing uses nonsense syllables with no meaning, while vocalese takes an existing instrumental jazz recording and writes actual lyrics to fit the improvised melody.
Think of it this way: scat singing invents sounds on the spot, while vocalese writes words after the fact to a melody that already exists. Eddie Jefferson, King Pleasure, and Lambert, Hendricks & Ross are the names most associated with vocalese, while Louis Armstrong and Ella Fitzgerald are the icons of scat.
If you’re listening and you hear recognizable English lyrics riding on top of a bebop line, that’s vocalese. If you hear “ba-da-ba-shoo-wop” flying out of a singer’s mouth, that’s scat singing.
History and Origins of Scat Singing
The most famous origin story of scat singing lands in 1926, when Louis Armstrong was recording “Heebie Jeebies” with his Hot Five. The legend says his sheet music fell off the stand mid-take, and instead of stopping, Armstrong invented nonsense syllables to keep the melody going. The result was so infectious that the take was kept and released.
Whether the story is fully accurate is debated, but “Heebie Jeebies” is widely credited as the first recorded example of scat singing. Armstrong’s playful, loose phrasing set the template that other jazz vocalists would build on for the next century.
Why is it called scatting? The word itself has murky roots. Some trace it to slang, others to onomatopoeia from the sounds singers made. The earliest mentions in print appear in the late 1920s, but the practice of wordless vocal improvisation has roots stretching back further.
Historians point to West African vocal traditions, where singers used rhythmic, nonverbal sounds in ceremonies and storytelling. In the United States, vaudeville and blues performers in the early 1900s also toyed with wordless vocal lines long before Armstrong’s recording made the style famous.
Scat singing really took off in the swing era of the 1930s, when big bands gave vocalists room to shine as soloists. Cab Calloway turned scat into theatrical showmanship with his signature “Hi-De-Ho” chants, while Slim Gaillard and Slam Stewart built careers around playful wordless invention.
In the 1940s, bebop pushed scat singing into a more complex direction. Charlie Parker and Dizzy Gillespie’s rapid-fire instrumental lines inspired vocalists like Ella Fitzgerald and Sarah Vaughan to match that speed and harmonic sophistication with their voices. Scat became less about playful sounds and more about serious improvisational skill.
Famous Scat Singers You Should Know
Scat singing has produced some of the most iconic moments in jazz history. These are the artists whose solos shaped the tradition and continue to influence vocalists today.
Louis Armstrong is widely considered the father of scat singing. His 1926 “Heebie Jeebies” recording popularized the style, and his loose, conversational phrasing made wordless improvisation feel warm and human rather than technical.
Ella Fitzgerald took scat singing to heights nobody else reached. Dubbed the “First Lady of Song,” she had an encyclopedic ear for chord changes and could improvise at blistering bebop speeds. Her solo on “How High the Moon” is a masterclass in melodic invention.
Sarah Vaughan brought operatic range and rich tone to scat singing. Her voice carried a depth that few could match, and her improvisations wove effortlessly between lush balladry and quick horn-like runs.
Cab Calloway made scat theatrical. His “Hi-De-Ho Man” persona turned wordless singing into show business, complete with call-and-response crowd energy and larger-than-life stage presence.
Betty Carter pushed scat singing into avant-garde territory in the 1970s and 80s. She stretched timing, bent pitches, and used her voice with the freedom of a free jazz horn player. Her influence on modern jazz vocals is enormous.
Al Jarreau took scat beyond jazz, blending it with pop, R&B, and Latin rhythms. His ability to mimic percussion, basslines, and horns with just his voice earned him seven Grammys across multiple genres.
Bobby McFerrin represents the contemporary face of scat singing. His 1988 hit “Don’t Worry, Be Happy” introduced wordless vocal techniques to a global pop audience, and his solo vocal performances show what a single voice can do when treated as a full band.
Kurt Elling and Gregory Porter carry the tradition forward today. Both incorporate scat into modern jazz settings, proving the technique still has plenty of creative life in 2026.
Common Scat Syllables and How They Work
One of the biggest questions beginners ask is what syllables to use when scatting. There is no official dictionary, but experienced jazz singers tend to fall back on a core set of sounds.
The most common scat syllables include “ba,” “da,” “doo,” “shoo,” “wop,” “bop,” “ski,” “wa,” “la,” and “zwee.” Mix them together and you get phrases like “shoo-bee-doo-wop” or “ba-da-ba-da-shoo.”
The choice of syllable shapes the articulation. Hard consonants like “b,” “d,” and “t” give a percussive, trumpet-like attack. Softer consonants like “sh” and “w” create a smoother, gliding sound closer to a trombone or flute.
A useful trick from jazz vocalists is to imitate specific instruments. Pick a horn solo you love and try to match its phrasing with your voice, choosing syllables that mimic the articulation. This trains your ear for jazz phrasing and gives you a built-in vocabulary of syllables that already work.
One common pitfall: beginners often default to a single syllable like “da” repeated over and over. That makes articulation harder and the solo monotonous. Vary your syllables the way a horn player varies their attack.
How to Scat Sing: A Beginner’s Guide
Yes, anyone can learn to scat sing. You don’t need perfect pitch or years of training to start. You just need a willingness to experiment with your voice and a basic sense of rhythm. Here is a step-by-step path that professional jazz teachers and forum contributors recommend.
Step 1: Listen deeply to scat masters. Spend time with Ella Fitzgerald, Louis Armstrong, and Betty Carter before you try to improvise yourself. Their phrasing, syllable choices, and rhythmic feel become your internal reference library.
Step 2: Imitate a horn solo you love. Pick a short trumpet or saxophone phrase and sing it back using nonsense syllables. This trains you to think like an instrumentalist, which is the whole point of scat singing.
Step 3: Learn the chord progression of a simple tune. A 12-bar blues is the perfect starting point. Once you know the roots, thirds, and sevenths of each chord, you have a roadmap for where your improvised lines can land.
Step 4: Practice with a metronome on beats 2 and 4. This is a classic jazz exercise that locks your internal sense of swing. Set the metronome slower than the actual tempo and feel the off-beats rather than chasing every click.
Step 5: Start with short phrases. Don’t try to improvise a full chorus on day one. Build two-bar phrases first, then extend them. Rests are part of the music, just like in a horn solo.
Step 6: Record yourself and listen back. This is uncomfortable at first, but it’s the fastest way to hear what works and what doesn’t. You’ll catch pitch issues, weak syllables, and timing drift that you can’t feel in the moment.
Step 7: Scat along with backing tracks. Once you’re comfortable alone, sing over recorded rhythm sections. This builds the real-time listening skill that separates good scat singers from people who just make sounds.
Most beginners feel embarrassed at first, and that’s normal. Scat singing sounds silly when you’re new, and improvising in front of others can feel exposing. Every jazz vocalist starts there. The key is to push through the awkward phase by practicing alone, recording yourself, and treating mistakes as information rather than failure.
If you want structure, start with a simple routine: five minutes of horn imitation, five minutes over a blues progression, and five minutes of free scatting over a track you love. Fifteen minutes a day will transform your comfort level within a month.
