Zither and the 'Third Man' Theme

You might not recognize the zither by name, but you've almost certainly heard it. It's one of the world's oldest stringed instruments, with roots stretching back to a 403 B.C. Chinese tomb. Its most famous moment came when self-taught Viennese player Anton Karas recorded The Third Man theme, which spent eleven weeks at number one on the Billboard chart in 1950. There's much more to this remarkable instrument's story than you'd expect.

Key Takeaways

• The zither is one of the world's oldest instruments, with China's guqin dating to a 403 B.C. tomb.
• Anton Karas, a self-taught Viennese zither player, was discovered by director Carol Reed at a 1948 party.
• Studio executives initially opposed scoring The Third Man with solo zither, preferring a full orchestra accompaniment.
• "The Harry Lime Theme" spent eleven weeks at number one on Billboard's U.S. Best Sellers in Stores chart in 1950.
• Combined versions of the theme have sold an estimated 40 million copies, finishing as 1950's third-best-selling single.

What Exactly Is a Zither?

A zither is a stringed instrument whose strings stretch horizontally across a flat, shallow body that doubles as the soundboard — unlike guitars or lutes, it has no distinctly separate neck.

You'll find string counts ranging from a single string on a monochord to over fifty on concert models.

Despite origin myths suggesting purely European roots, the oldest known zither is China's guqin, discovered in a 403 B.C. tomb.

The word itself traces back to the Greek and Latin "cithara," the same root that gave us "guitar."

Playing posture typically involves resting the instrument across your knees or on a table, keeping both hands free — your left hand stops the melody strings while your right hand plucks and strums accompaniment strings. The right thumb specifically uses a plectrum for melody strings, while the fingers handle the unstopped accompaniment strings independently.

Much like the zither's cultural reach, the concept of an ideal yet unreachable society was famously explored by Sir Thomas More in his 1516 book Utopia, which sparked an entirely new literary genre.

How Did a Folk Instrument Conquer the Concert Stage?

Once you understand what a zither is, its leap from rustic folk instrument to concert hall staple becomes even more striking. Max Amberger's 1862 redesign, based on Weigel's plans, transformed the old Volkszither into a sophisticated concert instrument with five melody strings and up to 37 accompaniment strings, giving it a range exceeding both piano and guitar at 187 basic tones.

This conservatory adaptation opened doors to urban salons and serious composers. Between 1870 and 1910, Altmeister virtuosi like Hans Drechsel and Georg Freundorfer wrote classical repertoire specifically for the instrument. Even Johann Strauss II took notice, featuring a prominent zither solo in "Tales from the Vienna Woods." Emigration then carried the concert zither across North and South America, cementing its global legitimacy. The mathematical patterns underlying musical harmony, such as those found in Pascal's triangle, have long helped theorists analyze the intervallic relationships that make instruments like the zither so tonally rich.

The instrument's international resurgence received an unexpected boost when Anton Karas performed the entire soundtrack of the 1949 film The Third Man on a concert zither, with The Third Man Theme spending eleven weeks at number one on the Billboard U.S. Best Sellers in Stores Chart. Much like the zither's freely shared musical traditions, Tim Berners-Lee's decision to release HTTP and HTML specifications without patents or royalties in April 1993 demonstrated how open access can transform a specialized tool into a global phenomenon.

What's Inside a Zither: Strings, Frets, and Sound Box

Crack open the anatomy of a concert zither, and you'll find three interlocking systems working together: strings, frets, and a sound box.

A concert zither typically carries 29–38 strings, divided into fretted melody strings, accompaniment, bass, and contrabass sections. Red-colored C#, F, and A strings mark reference points across unfretted sections.

The fretted fingerboard sits above guitar-like frets, enabling precise intonation for melody strings. Post-1960 models replaced half-frets with full-length frets for improved playability.

String vibration drives everything — strings produce primary frequencies plus overtones, transferring energy through the bridge into the shallow wooden sound box. Strings are poor sound emitters and depend on the resonator to amplify their vibrations into audible sound.

Resonance mechanics then take over, with the bridge filtering harmonics selectively, exciting specific modes in the wood, air space, and lower resonance surface to shape your final tone.

How Do You Actually Play a Zither?

Understanding what's inside a zither is one thing — actually playing it's another. Your sitting posture matters from the start: sit at the edge of a straight-back chair, relax your shoulders, and angle the zither so its right edge points toward your belly button.

Your right hand handles the melody strings, while your left hand presses chords on the fretboard. With your right hand, raise your knuckles to form a cave under your fingers, then pluck using a pick. Your left hand uses a pulling, petting stroke from high to low strings.

Finger conditioning takes time, so practice just 30 minutes daily to avoid soreness. Begin with simple three-note songs like "Mary Had a Little Lamb" to build confidence early. When tuning your instrument, always wear eye protection since strings on instruments left untuned for long periods are prone to snapping unexpectedly.

How the Zither Traveled From the Alps to America

The zither's journey from the Alpine highlands to American shores began with waves of 19th-century emigrants who carried their instruments across the Atlantic. Groups like the Styrian Alpine Singers and Tirolean National Singers performed internationally, spreading Alpine migration patterns that introduced zithers to new audiences. German immigrants brought concert zithers during the Gold Rush, Civil War, and Wild West era, embedding the instrument into American life.

You can trace the American revival back to 1879, when Franz Waldecker launched The Zitherplayer, the first U.S. zither newsletter, connecting players across states and Europe. Despite a deliberate erasure of zither history in the early 1900s, its popularity resurged through mid-century recordings by artists like Ruth Welcome, keeping the Alpine tradition alive on American soil. One figure whose influence extended even beyond Europe was Johann Petzmayer, who was awarded the rank of Kammervirtuoso by Duke Max in Bayern in 1838 after teaching the duke, helping elevate the zither's status among nobility before its cultural reach crossed the Atlantic.

The Viennese Street Musician Who Made the Zither Famous

Few stories in music history match the unlikely rise of Anton Karas, a self-taught zither player from Vienna's working-class Brigittenau district.

His journey from Viennese streetcorner performer to global icon unfolded through hard work and one extraordinary encounter:

1. Zither apprenticeship: He discovered a concert zither at 12, studied evenings at Pollux musician school (1920–1924), then trained at Vienna Music Academy until 1928.
2. Career start: By 17, he was performing at Heurigen restaurants for tips.
3. The breakthrough: Director Carol Reed heard him play at a 1948 party and immediately chose him to score The Third Man.
4. Global impact: By 1949's end, "The Harry Lime Theme" had sold half a million copies, making Karas a worldwide sensation overnight.

Despite resistance from studio executives, the zither score was ultimately celebrated worldwide for perfectly capturing Vienna's atmospheric underbelly, with the theme spending eleven weeks at number one on the Billboard charts in 1950.

How Did a Zither Track Spend Eleven Weeks at Number One?

Rarely does a single instrument dominate pop charts, yet Anton Karas's zither recording of "The Harry Lime Theme" spent eleven weeks at number one on *Billboard*'s United States Best Sellers in Stores chart, from April 29 to July 8, 1950.

This zither phenomenon wasn't a fluke. The US single dropped in February 1950, perfectly synchronized with the film's American theatrical debut, creating momentum across both channels simultaneously. Even Guy Lombardo's competing guitar version couldn't break Karas's chart dominance, holding only the number two position throughout most of his run. Four additional versions charted that same year.

The recording finished as the third-best-selling single of 1950, and combined versions have since sold an estimated 40 million copies collectively. The theme's extraordinary success sparked American exotica interest, triggering a pop zither wave that would sustain itself for roughly a decade before fading into cultural memory.

Why Did Carol Reed Score The Third Man With Only a Zither?

1. Studio executives Alexander Korda and David O. Selznick actively opposed the single-instrument approach.
2. Reed originally planned to blend Karas's zither with a full orchestra.
3. Hafenrichter pushed for unaccompanied zither throughout the entire film.
4. Vienna waltzes were rejected as too obvious an alternative.

The zither's transparent quality let the music start and stop naturally, adding empathy to quiet scenes while lightening sinister ones beautifully. Karas wrote and recorded approximately 40 minutes of music over just six weeks at Shepperton Studios, where the entire film was translated for him.

Linda McCartney, Basia Bulat, and Other Unexpected Zitherists

The zither's haunting role in The Third Man might make it seem like an instrument reserved for film scores and folk traditions — but it's popped up in some genuinely surprising hands over the decades. Linda McCartney, widely remembered as a Wings keyboardist, reportedly explored the zither privately.

Canadian singer-songwriter Basia Bulat has championed the instrument publicly, incorporating it into her indie folk sound and helping drive a broader Zither Revival. These Female Zitherists challenge assumptions about who plays the instrument and why.

You'll find the zither appearing across genres — folk, indie, experimental — carried by musicians who discovered its resonant, layered sound and refused to leave it behind in the silent film era where most people mentally shelved it. Linda McCartney, who became vegetarian in 1975 and was known for her fierce advocacy of animal rights, brought a similarly unconventional spirit to every creative pursuit she embraced.

Is the Concert Zither Growing in Popularity Again?

After Anton Karas's "Third Man Theme" topped the U.S. Billboard chart in 1950, interest eventually faded by the 1960s. Today, no data confirms a broad community resurgence, though small pockets of activity persist. You'll find the concert zither living in a niche world:

1. Traditional regions — Austria, Slovenia, Hungary, and Alpine Europe still maintain active players.
2. Folk gatherings — Zither returns at reunions and Christmastime, though without original dance contexts.
3. Innovators — Contemporary musicians attend the occasional zither workshop, exploring new genres.
4. Ornamental ownership — Most concert zithers sell for amateur or decorative purposes due to demanding technique requirements.

No recent chart surges or sales spikes suggest mainstream revival. The zither remains a refined, technically challenging instrument appreciated by dedicated few. A striking example of a plucked string instrument finding modern global audiences is Peng Jingxuan, a Chinese master's student whose guzheng street performances in France attracted over 6 million fans online.
