Varieties The fluier family includes at least 17 structural varieties. They differ by several features: they can be single or double, end-blown, transverse or semi-transverse, open or equipped with a fipple, with a varying number of finger-holes – from five to eight or none at all. By size, fluiers are divided into small (up to 35 cm), medium (35–50 cm), and large (50 cm and above). They are made from various types of wood (ash, willow, plum, dogwood, hazel, elder, maple), as well as reed, and very rarely, bone. In the 20th century, metal (brass, copper, aluminum) and even plastic began to be used. The diversity of forms within this family reflects the historico-typological evolution of the instrument – from the most archaic and simple variants (e.g., the tilinca and the Moldavian fipple-less fluier) to more technically advanced and later developments, such as the caval, the fipple fluier, double fluiers, and transverse flutes. In Romanian folk music, alongside traditional fluiers, borrowed wind instruments such as the
nai (panpipes) and the
ocarina are also found. Despite some common features with fluiers, they have a different structure and origin and are not considered part of the fluier family proper.
Open semi-transverse fluiers (fipple-less) Tilinca The tilinca ( or , cf. Ukrainian
telenka) is the simplest Romanian fluier, having no finger-holes and no fipple. The instrument is a tube made of wood (willow, maple, elder) or bark, open at both ends. Its length ranges from 65 to 80 cm. The melody is created exclusively by varying the strength of the air stream (overblowing), which allows the
overtones of the natural harmonic series to be produced, and also by partially or completely closing the lower end of the tube with a finger. Before playing, the instrument should be thoroughly soaked in water to ensure uniform moisture and wall consistency. The timbre of the tilinca is described as high, whistling, and with a characteristic sharpness. Despite its primitive construction, virtuoso performers can play not only doinas but also complex songs and dances on the tilinca. By the mid-20th century, this archaic instrument had become rare, found mainly in Bukovina, northern Moldavia, and Transylvania. The concert and educational activities of Bukovinian master and folk musician Mihai Lăcătuș helped save the tilinca from oblivion, contributing to the preservation and gradual revival of its performance tradition in the region.
Moldavian fluier Open semi-transverse fluiers with six finger-holes () are common in the northern part of the historical region of Moldavia, as well as partially in northern Transylvania. Tiberiu Alexandru called this type the Moldavian fluier (). The instrument is a cylindrical tube with open ends and a semi-transverse (oblique) embouchure, without a fipple. It is made predominantly of wood, less often of metal. Small, medium (less common), and large varieties exist. In the north and northwest of Romanian Bukovina, the small fluier is called a , while the large instrument is called a (Romanian for "large fluier"). In central Moldavia, the small instrument may be called a , and the large one a , by analogy with the Oltenian caval.'''' In Ukrainian Bukovina, Moldavian fluiers of increased length (50–80 cm and more) are called long fluiers or large fluiers (). The term "small fluier" () refers to instruments measuring 25–35 cm in length. The term "" is not found in the Northern Bukovinian tradition. Unlike the more common fipple flutes, the Moldavian fluier requires the performer to form an air stream with the lips, directing it onto the edge of the hole. This allows for a rich timbral palette, fine dynamics, and expressiveness. The sound of the Moldavian fluier is typically softer, warmer, and richer in overtones, whereas fipple flutes produce a bright, stable, but less flexible sound. The fipple-less fluier is considered a more archaic form compared to the instrument with a fipple. Researchers view the Moldavian fluier as a transitional form between the tilinca and the more widespread fipple fluiers.
Dobrujan fluier The Dobrujan fluier () is a fipple-less fluier common in the Dobruja region. Unlike the Moldavian fluier, which has six finger-holes on the front, the Dobrujan fluier is equipped with seven holes: six on the front and one additional on the back, slightly above the sixth. Opening the back hole typically raises the fundamental tone by an octave. The instrument is usually made of reed.
Bulgarian kaval In Dobruja, Romanians also play the Bulgarian kaval (). This instrument, 65–90 cm long, consists of three tubes fitted into one another, secured at the joints with rings of ox horn. The upper section (26–27 cm) (nearest camera) has an opening for blowing air that has a
beveled edge around its entire circumference, in common with most fipple-less flutes. It connects to the main tube (25–27 cm), which has seven finger-holes cut on one side, either equidistant or in two groups of three and four (from top to bottom). On the opposite side, above the others, is a left thumb hole. The right thumb supports the instrument. The main tube is inserted into the lower section (21–25 cm), which has four open holes: two inline with finger-holes and two opposite each other on either side, located at three different distances from the bottom edge (between 7 and 23 cm).
Closed end-blown fipple-less fluiers Fifa The fifa () is a type of fluier found in certain areas of Oltenia (southern Romania). It is a unitonal (one-note) fluier traditionally played by young unmarried girls. Playing the fifa alternates with vocal calls of
hăulit, which resemble
yodeling in sound.
End-blown fipple fluiers Tilinca with a fipple This variety of the tilinca is equipped with a fipple, which significantly facilitates sound production compared to the open version. Like the fipple-less tilinca, it has no finger-holes, and the melody is played exclusively by overblowing, based on the sequential production of overtones of the natural harmonic series. This type of instrument was described by Béla Bartók in 1913 in Maramureș.
Caval The Romanian caval is common in Oltenia, Muntenia, Dobruja, and the southern part of Moldavia. The instrument is made of wood, has a cylindrical tube, and five finger-holes, which are always grouped (from bottom to top) in two sets of two and three. The distance from the lower end of the caval to the first finger-hole is slightly greater than the distance from it to the third; the distance between the groups of holes – that is, between the second and third hole – is slightly greater than the sum of the distances between the other holes, and the distance from the lower end to the fifth hole is slightly more than half the length of the fluier. Like any fluier with finger-holes, the caval produces a fundamental tone when all holes are closed, and a scale when the holes are successively opened from the bottom up. Because there are only five holes, the resulting scale is limited to six notes and is incomplete; it can be raised by an octave or more by increasing the force of the air stream. Due to its limited range (usually within a sixth, and sometimes less), not every melody can be played on the caval. The timbre of the caval is soft, velvety, somewhat gentle and sad, and it imparts this character to the melodies played on it. It is most often used to play slow pieces: doinas, songs in free rhythm (rubato), and calm dance melodies. Some performers use a technique called "playing with the lip" (). This technique consists of partially covering the fipple's window () with the lower lip. This position not only allows for a greater volume of sound due to a stronger exhalation, but also changes the timbre: the instrument sounds slightly lower, and the sound acquires the character of a delicate
frullato, resembling the sound of reed instruments, such as the
clarinet or the
tárogató.
Fluier with a fipple The fluier with a fipple and six finger-holes () is the most numerous type of Romanian folk flute. It is common throughout the entire Romanian cultural area and is most popular in Oltenia, Muntenia, Dobruja, and southern Moldavia. Its key feature is the presence of a fipple, which significantly facilitates sound production compared to fipple-less flutes. The fipple (, Romanian for "plug") closes the upper end of the tube, which is usually thicker, leaving a narrow rectangular air channel (0.6–0.8 cm long and 0.1–0.15 cm wide) known as the "light" (), "eye" (), or "breather" (). At a distance of 1.5–2 cm from the top, on the side opposite the finger-holes, a rectangular or square window () is cut. The lower edge of the window is sharply beveled and is called the "lip" or "tongue" (). As the air passes through the channel, it is split by this sharp edge, creating vibration and thus sound. Fipple flutes are almost always made of wood. The outer profile of the tube is slightly conical, and the finger-holes are most often oval, arranged in two groups of three. The distance from the lower end of the fluier to the first finger-hole is greater than the distance between the other holes (up to twice the distance, rarely more), and slightly greater than the distance between the two groups of holes. The sixth hole is located approximately halfway between the window's lip () and the lower end of the tube. At the lower end, the tube is left with thicker walls for a short distance or is closed with a plug (, Romanian for "bottom"), which leaves a small central hole about 0.5 cm in diameter. In Oltenia, Muntenia, Dobruja, and southern Moldavia, it is called a . In Banat and the adjacent areas of Transylvania and Oltenia, it is called . In Bukovina, northern Moldavia, and most of Transylvania, it is called . The most common types are the small instruments, sometimes referred to as or , and the medium ones. The large ones (in Transylvania, or ) are rarer. They are primarily used in the
Sibiu,
Hunedoara, and northern Oltenia regions. When played, the instrument is held straight, unlike semi-transverse and transverse flutes. The tongue plays an important role in performance. To create detached, clear sounds (staccato), especially in dance music, performers coordinate finger movements with tongue strikes that rhythmically block the air channel. Alexandru quotes a fluier player from Vrancea: "When the finger strikes, the tongue strikes too." Sometimes performers play two identical fluiers simultaneously, holding them in their mouths and playing the melody in unison. Occasionally, a fipple fluier is built into the upper part of a shepherd's staff (, Romanian for "fluier in a club"). The tube runs inside the staff; its lower end has a small oblique channel that exits to the surface through a hole in the staff's wall. This hole is analogous to the lower end of a regular fluier and is located on the opposite side of the finger-holes. Below the built-in fluier, the staff continues to its normal length and shape. This design combines two essential items of shepherd life – the staff as a utilitarian tool and the fluier as a musical instrument. There is also a fluier-whip (), in which the fluier serves as the whip handle. Fluiers from the Vrancea region may have a special protrusion with a hole () on the back of the tube, designed for tying the instrument to a belt, for example.
Double fluier The double fluier (; also known as ) consists of two fipple flutes joined (cf.
double flute). Such instruments are made either from a single piece of wood or by joining two separate tubes. Double fluiers are relatively rare, partly due to the complexity of their manufacture and their higher cost compared to regular fluiers. Typically, in a double fluier, one tube has six finger-holes and is used for playing the melody, while the second, of the same length and without holes, produces a continuous drone tone. In terms of playing technique, such an instrument is close to the widespread fipple fluier with six holes and does not require special training. Varieties with seven holes or with a shortened drone pipe are rarer. If both tubes are of the same length, the second (without holes) produces a drone in unison with the fundamental tone of the melody pipe; if it is half as long, it sounds an octave higher. Occasionally, double fluiers are found where both tubes are equipped with six finger-holes.
Transverse fluiers In some parts of eastern Oltenia, folk transverse flutes are found. The large examples are called flutes (), and the small ones are called . They are tubes closed at one end, near which an embouchure hole is cut into the wall. On the same side are six or seven finger-holes; on large flutes, they are often grouped in two sets (3+3 or 4+3). During performance, the instrument is held in a transverse position relative to the player's body. The playing technique on folk flutes and piculinas is analogous to that of modern transverse flutes: the sound is produced by splitting the air stream directed by the player against the edge of the hole. The characteristic guttural hum that accompanies traditional fluier performance is also found when playing these instruments. == Manufacturing ==
