Why Is It Called a Setar When It Has Four Strings?

The Meaning Behind the Name Setar

Anyone examining a modern setar for the first time may notice an apparent contradiction. The instrument has four tuning pegs and four metal strings, yet its name literally means “three strings.” This often leads new musicians to wonder whether the name has been mistranslated or whether one of the strings does not count.

The explanation is rooted in the instrument’s history.

The word comes from two Persian terms: “se,” meaning three, and “tar,” meaning string. When the instrument received its name, it was constructed with three strings. The fourth string was introduced much later, after the original name had already become firmly associated with the instrument.

Rather than being an error, the name preserves an earlier stage in the instrument’s development. It is a reminder that musical instruments can evolve considerably while retaining names that reflect their original construction.

How Persian Instruments Were Named by Their Strings

The name is part of a wider naming pattern found among Persian and Central Asian stringed instruments. Historically, several instruments were identified by combining a number with the Persian word “tar,” which means string.

Examples include:

• Dotar or dutar: “do” means two, referring to a two-stringed instrument
• Setar: “se” means three, referring to its original three-string arrangement
• Chahartar: “chahar” means four
• Panjtar: “panj” means five
• Sheshtar or shashtar: “shesh” means six

These names could describe the number of strings originally used on an instrument, even if its construction changed later. They also helped distinguish related members of the long-necked lute family.

This naming approach provides important historical information. Before standardized instrument catalogues, recordings, photographs, and detailed construction manuals existed, an instrument’s name could communicate one of its most recognizable physical features.

The name setar therefore functioned as a practical description. It identified a long-necked Persian lute that, at that time, had three strings.

The Original Three-String Design

The early setar belonged to a broad family of long-necked lutes that developed across Iran, Central Asia, and neighbouring regions. Historical forms varied, and it is difficult to identify one fixed design that applies to every century. However, the instrument is widely understood to have originally used three strings.

Its body was small compared with many other lutes, and its sound was intimate rather than forceful. A long neck fitted with movable frets gave musicians access to the intervals required in Persian music, including notes that do not correspond directly to the twelve equally spaced tones of a modern piano.

The lightweight wooden bowl, thin soundboard, metal strings, and fingernail playing technique produced a detailed and sensitive voice. Small differences in the player’s touch could noticeably change the tone, volume, and character of a note.

With three strings, musicians could play melodies, create rhythmic patterns, and use open strings for resonance. The instrument’s structure was already capable of expressing the melodic detail of Persian classical music. The later addition of another string did not replace this identity. It expanded the tonal possibilities available to the performer.

Who Added the Fourth String?

The addition of the fourth string is traditionally attributed to Moshtaq Ali Shah, an eighteenth-century Iranian mystic and musician associated with Kerman. Historical accounts commonly credit him with adding a new string to the previously three-stringed instrument.

Because of this association, the added string is often called the Moshtaq string or sim-e Moshtaq. In Persian, “sim” can refer to a wire or musical string.

It is helpful to describe this account as a traditional attribution. The history of instruments is not always documented with the precision expected from modern records. Designs can change gradually, regional experiments may occur independently, and later musicians may preserve different versions of the same story.

Even so, the connection between Moshtaq Ali Shah and the fourth string is deeply established in the instrument’s musical history. His name remains attached to the modification because the added string significantly influenced the instrument’s resonance and tuning options.

According to the Center for World Music, this additional drone string created a fuller sound and offered musicians more complex tuning possibilities. The instrument still retained its delicate character, but its harmonic response became richer.

What Does the Fourth String Actually Do?

The fourth string was not simply added to make the instrument louder. Its value comes from the way it interacts with the other strings and supports the mode being performed.

Greater Resonance

An open string can continue vibrating while a musician plays notes on another string. It may also respond sympathetically to related frequencies produced elsewhere on the instrument.

This interaction creates a sense of depth around the melody. The sound remains light and controlled, but it gains a fuller harmonic background. On a well-made instrument, listeners may hear more than the individual note being plucked. They also hear a surrounding field of vibration produced by the body and open strings.

A Stronger Drone Effect

Drone tones are important in many musical traditions. They establish a tonal centre and help define the atmosphere of a mode or composition.

The added string can be tuned according to the dastgah, avaz, or specific piece being performed. When used as a drone, it reinforces important pitches and gives melodic phrases a stable tonal foundation.

This does not mean that it is constantly producing a separate melody. Its role is often supportive. It adds colour, continuity, and resonance beneath or around the principal melodic line.

More Tuning Possibilities

Persian classical music uses several modal systems, each with its own melodic behaviour, important notes, and emotional character. Players may change the tuning of the open strings to suit the repertoire they plan to perform.

The extra string creates additional tuning relationships. A musician can select a pitch that complements the principal mode, strengthens a frequently used note, or contributes a desired resonance.

This flexibility is one reason the four-string arrangement remained useful. The modification served a genuine musical purpose rather than being a decorative alteration.

Does the Instrument Still Function Like It Has Three Strings?

The modern instrument physically has four separate strings, each attached to its own tuning peg. From a construction standpoint, there is no uncertainty. It is a four-stringed instrument.

Musically, however, the strings are not always treated as four completely independent melodic voices. The lower strings can work closely together as part of a shared bass or drone function. Some descriptions therefore explain the instrument as having four strings arranged into three functional groups or courses.

This helps explain why the old name may still feel musically appropriate. The fourth string expanded an existing area of the instrument’s sound instead of turning it into an entirely different type of lute.

However, it would be misleading to say that the fourth string does not count. It is a real and essential part of the modern design. Its presence affects tuning, resonance, fingering decisions, and the overall response of the instrument.

The clearest explanation is that the name describes the instrument’s historical origin, while the current construction reflects its later development.

Why Was the Name Never Changed?

Musical instrument names rarely change every time a design is modified. Once an instrument becomes recognized by musicians, teachers, builders, poets, and audiences, its name takes on a cultural meaning greater than its literal definition.

Renaming it after the addition of the fourth string could have created confusion. More importantly, the new string did not erase the instrument’s earlier musical identity. Its body shape, playing method, repertory, and characteristic voice remained connected to the established tradition.

This pattern is not unusual in music. Instrument names frequently survive changes in materials, dimensions, tuning systems, string counts, and construction techniques. A name may begin as a literal description but eventually become the proper name of a distinct instrument.

Once that happens, historical continuity becomes more important than numerical accuracy.

Calling the instrument a chahartar, meaning four strings, would also have created complications because that term had already been used for other long-necked lutes. Encyclopedia Iranica notes that chahartar historically referred to four-stringed instruments and was also applied to regional variants related to the broader tanbur family.

Keeping the familiar name allowed musicians to recognize the instrument as an evolved form of the same Persian lute rather than as an entirely new creation.

How the Four Strings Are Commonly Identified

Terminology can vary among teachers and musical traditions, but the strings of a modern Iranian instrument are often described as follows:

The White String

The white or silver-coloured steel string is commonly used as an important melody string. Its clear response helps produce the bright, precise articulation associated with the instrument.

The Yellow String

The yellow string is traditionally made from brass or another yellow-coloured metal. It provides a warmer tonal contrast and can also carry melodic material.

The Moshtaq String

The added string is known as the Moshtaq string in recognition of Moshtaq Ali Shah. It is generally positioned between the yellow string and the bass string.

Its tuning can change according to the musical mode and the player’s preference. It often contributes a drone or sympathetic resonance that enriches the performance.

The Bass String

The bass string provides lower tones and added depth. It can support rhythmic patterns, drone effects, and melodic passages in the lower register.

These strings work together to create a sound that is larger than the instrument’s compact wooden body might suggest. The combination of open-string resonance and detailed fingernail strokes gives it a recognizable voice within Persian music.

The Role of the Player’s Fingernail

Unlike many plucked instruments, the Persian setar is traditionally played with the fingernail of the right index finger rather than with a separate pick.

The player uses controlled inward and outward movements to strike the strings. This approach allows for rapid tremolo, delicate single notes, accented attacks, and subtle changes in tone.

Because the instrument is highly responsive, the shape, strength, and angle of the fingernail can influence the sound. A small adjustment in technique may make the tone softer, sharper, warmer, or more percussive.

The fourth string contributes to this playing experience because a stroke can activate multiple strings or encourage nearby open strings to resonate. The result is not simply the sound of four isolated wires. It is a connected acoustic system in which the player’s touch, the tuning, and the wooden body continuously interact.

How the Fourth String Changed the Instrument’s Character

The added string increased the range of textures available to musicians without sacrificing the instrument’s quiet and personal quality.

Players gained more control over resonance and tonal emphasis. They could reinforce important notes in a dastgah, create a more persistent drone, and allow certain melodic phrases to ring with greater complexity.

The modification also gave performers additional creative choices. The same passage can feel different when the fourth string is tuned to another pitch. One tuning may create warmth and stability, while another may introduce tension or emphasize a contrasting tonal centre.

For advanced musicians, these details are part of interpretation. Tuning is not merely a technical preparation completed before the performance. It can shape the colour and direction of the music itself.

What New Players Should Understand

A beginner should not be concerned that the name and string count appear inconsistent. Modern instruments are designed, taught, and played with four strings.

When purchasing one, the player should expect:

• Four strings and four tuning pegs
• A small wooden bowl, commonly made from mulberry
• A long neck with movable tied frets
• A thin wooden soundboard
• Metal strings with different tonal roles
• Traditional playing with the index fingernail
• Tuning that may change according to the piece or mode

The exact materials, dimensions, workmanship, and tonal balance can differ significantly from one maker to another. The quality of the bowl, neck, bridge, nut, pegs, frets, and strings all influence comfort and sound.

Beginners should also understand that tuning advice may vary. There is no single permanent tuning used for every piece of Persian music. A teacher may recommend different configurations depending on the student’s level and the repertoire being studied.

Do Not Confuse the Persian Setar with the Indian Sitar

The similar names sometimes cause confusion, but the Persian setar and Indian sitar are distinct instruments.

The Iranian instrument is smaller, has a compact wooden bowl, and normally uses four strings. It is played with the fingernail of the index finger and holds an important place in Persian classical music.

The Indian sitar is much larger and has a different body, bridge, string arrangement, playing technique, and musical tradition. It usually includes multiple playing and sympathetic strings and is played using a wire plectrum worn on the finger.

Their names share linguistic connections involving strings, but a person looking for one should not assume that the terms are interchangeable.

A Name That Preserves the Instrument’s History

The apparent mismatch between three in the name and four strings on the instrument is one of its most interesting characteristics. It allows musicians to see two stages of its development at the same time.

The name records the original three-string construction. The physical instrument records the later addition traditionally associated with Moshtaq Ali Shah. Together, they show how a musical tradition can accept a valuable innovation without abandoning its established identity.

The fourth string enriched the resonance, expanded tuning options, and gave performers greater control over drones and tonal colour. Yet the instrument remained connected to the design, technique, repertory, and cultural history that had already defined it.

That is why it is still called a setar. The name is not a mistake. It is a compact piece of musical history that has survived in everyday language.
