History & Origins
What is the venu?
The venu, or Carnatic flute, is the side-blown bamboo flute of Carnatic classical music, and ours, hand-tuned and tested across its range, suits the student and the concert flautist. Cut from a single internode of seasoned bamboo, it has one blow hole near the stopped end, eight finger holes set close together and no keys. A concert venu in the common E-flat pitch measures about 37–40 cm, and makers build every key: a longer, wider flute sounds lower.
How it sounds
Carnatic music rests on gamaka, ornamented movement between pitches. The player covers the holes with the finger pads and shapes gamaka with breath, lip and partial covering of a hole, oscillating or rolling the embouchure for South Indian raga's undulating phrases. Overblowing, cross-fingering, breath pressure and a refined lip angle carry about three octaves across lower, middle and upper registers, warm and full below, brighter above. On the venu, Sa sounds with the top two holes closed; the Hindustani bansuri closes three.
Tradition and choice
Indian art links the flute with Krishna; Vishnu appears as Venugopala. Sarabha Sastri brought the flute into Carnatic concerts and T. R. Mahalingam, Mali, made it a front-rank solo instrument. Choose traditional or modern designs, right- or left-handed layouts, bamboo or PVC, made in Chennai, Bengaluru and Thanjavur. It is a mainstay of Carnatic teaching, played across South India and worldwide. Start on one of our venu study paths.
The Natya Shastra (about 200 BCE to 200 CE) gives the bamboo flute as its hollow, sushira, example, a main melodic voice of drama and devotion. In the South the venu, or pullanguzhal, belongs to Krishna in Vaishnava poetry and temple art from the first millennium CE, which shaped its ritual status. Sangam-era Tamil texts (c. 3rd century BCE–3rd century CE) describe flute playing in secular and ritual settings, among the oldest recorded music of the subcontinent.
The venu long stood behind the veena at court, heard more in devotional and light music. Sarabha Sastri developed a fingering that brought it into Carnatic concerts. T. R. Mahalingam (1926–1986), known as Mali, taught himself, stressed pitch purity, made the venu a solo concert instrument and showed on record that a keyless flute could carry the depth of Carnatic gamaka in manodharma: alapana, neraval, kalpana swaras and pallavi.
His nephew and disciple N. Ramani (1934–2015) recorded widely and taught students now performing worldwide. Chennai makers build it in all twelve keys, E-flat or E most often; its low cost makes it a common way into Carnatic music, and it stands beside the violin and mridangam at the front of the stage.
Construction & Craftsmanship
Construction Process
The venu is cut from a single internode of bamboo, chosen for even walls, straight grain and no cracks or nodes in the playing length. Bamboos used include Dendrocalamus strictus and Phyllostachys species, harvested mature and seasoned for months against cracking. After cutting to length for its pitch, the maker burns or drills the oval blow hole, about 2–3 cm from the stopped end, and the eight finger holes, finishing each with a hot rod.
Hole size and spacing serve the Carnatic scale, sized so partial covering gives clean microtones; the eighth hole stays open except in special fingerings. The bore may be lightly oiled with sesame or almond oil. There are no keys or pads. Thread or wax binding protects the ends, above all the thinner blow-hole end, and the surface is natural, lightly lacquered or thread-wrapped.
Each flute is hand-tuned by the maker, holes filed or filled until the scale sits true and tested across the full range; tuning varies between flutes, so play every note before you buy. Some modern designs add a lip plate and up to nine holes, and PVC flutes also exist.
Maintenance & Care
- Blow warm air through before playing. Afterwards, dry the bore and leave the venu uncapped 10–15 minutes, or stand it upright, before casing; never put a wet flute away, as it breeds mould and softens the bamboo.
- Every few months oil the dry bore with sesame, almond, mustard or walnut oil on a swab, up to the blow hole. A thin film is enough to seal the grain against humidity swings.
- Below 35% relative humidity bamboo cracks; above 70% it swells. Keep it from vents and sun in a padded cotton bag, with a sachet in dry places, and warm a cold flute before playing.
- Rebind loose end bindings at once. Fine surface cracks are common and often harmless; a crack through to the bore changes the response, and one at the blow hole affects the embouchure and needs our repair. Bind a hairline crack with thread and beeswax, or glue and bind it.
- Clean the edges of each hole with a dry cloth or soft brush, and never file or enlarge a hole.

Frequently Asked Questions
Who made the venu, the Carnatic flute, a concert instrument?
Sarabha Sastri of Kumbakonam (1872 to 1904) developed a fingering system that brought the venu from folk use into Carnatic concerts. His disciple Palladam Sanjiva Rao made it a successful concert instrument. T. R. Mahalingam, known as Mali, then established it as a solo instrument, and his nephew and pupil N. Ramani founded the Ramani Academy of Flute in 1983.
What is the venu, the flute of Carnatic music?
The venu, also called the Carnatic flute or pullanguzhal, is the eight-hole flute of South Indian Carnatic music. Sa is fingered with the first two holes covered, and the eighth hole stays open except in special fingerings; the Horniman Museum catalogues it on one venu as a hole for tuning. The Music Academy traces how the flute grew from a folk and dance instrument into one that carries the ragas and gamakas of Carnatic music.
How can a beginner, a child or an adult returning after a long break start learning the Carnatic flute, the venu?
You can learn the Carnatic flute, the venu, with KalaSudha online and in workshops, and beginners start at Foundation level. Foundation builds the lip angle and breath support for a clear, centred tone. We teach children as well as adults; ask us about a starting age and about a flute size for a younger learner.
If you are returning after a long break, start again where you left off. Our courses run in levels, so your teacher first hears where you stand.
How does the venu differ from the bansuri?
The venu of Carnatic music has eight finger holes, with Sa fingered on the first two holes closed. The Hindustani bansuri has six finger holes in line with the blow hole, and Britannica describes six or seven. On the venu the eighth hole stays open except in special fingerings that cover all eight; the Horniman Museum lists it on one venu as a tuning hole.
How do I care for a bamboo venu or flute?
Dry the bore of a bamboo venu after each session, and never put it in a case or bag while it is drying, which can lead to mould. Bring the flute to room temperature before playing, avoid playing outdoors in the cold and never leave it in a hot car. Keep the thread bindings intact, and rebind them promptly.
What should I check before buying a venu?
Tuning varies between Carnatic flutes, so check the tuning of each venu. Each flute is made and tuned by hand, one at a time. Decide too between the traditional fingering and the Shashank style, which closes six holes for ma, and between the standard flute and a modern design with a lip plate.
Where can I buy a Carnatic flute (venu) outside India, with international shipping and service after the sale?
KalaSudha sells the Carnatic flute, the venu, to players outside India, by quote or made to order, and delivers worldwide. We pack every flute for international shipping; ask us about cases and insurance.
We also service and repair any venu, wherever you bought it, in any country. Ask us for spare parts too. For help with your flute once it arrives, use the chat on any page or email [email protected]. Gift vouchers, class sets for schools and flight cases for travel are available on request.
Should I oil my bamboo venu?
Oil the bore of a bamboo venu with mustard or walnut oil, only up to the blow-hole and only when the bore is dry. Oil a new flute after about 15 days of moderate play, then about every couple of months. Wipe the bore dry after each session, and keep the thread bindings intact.
How are the notes fingered on a venu, the Carnatic flute?
On the venu, Sa is fingered with the first two holes covered. In the traditional style, ma takes six and a half holes or a cross-fingering, while the Shashank style closes six holes for ma. The eighth hole stays open except in special fingerings, in which the fingers of both hands cover all eight.
How old is the flute in Indian and Carnatic music?
The flute behind the venu is one of the most ancient wind instruments, and in Indian culture it is associated with Krishna. A Music Academy lecture abstract notes that ancient flutes had fewer finger holes and limited ranges, and accompanied folk music, theatre and dance. The Silappatikaram, the Natyasastra, sculpture and painting record its history. It grew into an instrument for the ragas and gamakas of Carnatic music.
How do I book a Carnatic flute (venu) player for a concert, an event or a recording session?
Yes, KalaSudha can book a Carnatic flute (venu) player for your concert, event or recording. Send your request through our page to book Indian classical musicians. To hear our artists before you decide, listen to KalaSudha's recordings and watch our concert videos.
