Question: Thiruvalaputhur T A Kaliyamurthy is an artist that uses what type of instrument?

Context paragraphs:
Wind controller: A wind controller, sometimes referred to as a "wind synth", or "wind synthesizer", is a wind instrument capable of controlling one or more music synthesizers or other devices.  Wind controllers are most commonly played and fingered like a woodwind instrument, usually the saxophone, with the next most common being brass fingering, particularly the trumpet.  Models have been produced that play and finger like other acoustic instruments such as the recorder or the tin whistle.  One form of wind controller, the hardware-based variety, uses electronic sensors to convert fingering, breath pressure, bite pressure, finger pressure, and other gesture information into control signals.  Another form of wind controller uses software to convert the acoustic sound of an unmodified wind instrument directly into MIDI messages.  In either case, the control signals or MIDI messages generated by the wind controller are used to control internal or external devices such as analog synthesizers or MIDI-compatible synthesizers, softsynths, sequencers, or even lighting systems.

Electric instrument: An electric musical instrument is one in which the use of electric devices determines or affects the sound produced by an instrument.  Electric musical instruments are an example of electric music technology.  It is also known as an amplified musical instrument due to the common utilization of an electronic instrument amplifier to project the intended sound as determined by electric signals from the instrument.  Two common types of instrument amplifiers are the guitar amplifier and the bass amplifier.  This is not the same as an electronic musical instrument, like a synthesizer, which uses entirely electronic means to both create and control sound.

Yamudi: Yamudi (鴨母笛, 鸭母哒仔, or Taiwan guan 台湾管), is the native guan (instrument) of Taiwanese music.  The instrument, which translated means "mother duck flute" is very simple, as it primarily uses a large partially flattened tube reed connected to a thin cylindrical pipe (which may or may not have a small brass bell.)  A similar to the southern Chinese Luguan and Houguan, it is made of bamboo, instead of hardwood and uses a softer reed, giving it a more nasal buzzing sound than that of the northern Chinese guanzi which is hardwood with are harder reed.  This design also limits the instrument to a little more than an octave in range, since it cannot overblow like the guanzi.  It is primarily used in Taiwanese Folk opera for its somber sound.  Although native of Taiwan, it is becoming an increasingly popular instrument in China as well.

Thiruvalaputhur T A Kaliyamurthy: Kalaimamani Thiruvalaputhur T A Kaliyamurthy (born October 22, 1948) is a famous Thavil artist providing 'special' Thavil accompaniment ('Special' in percussion circles denotes selection-grade status and seniority) to the Nagaswaram maestros.

Stock-and-horn: The stock-and-horn was a traditional instrument of the Scottish peasantry, very similar to the Welsh pibgorn, consisting of a single-reed reed pipe amplified by a bell made of horn.  The original instrument of the Middle Ages had a double chanter with single reeds but was replaced by the single chanter type.  The single chanter instrument is described in great detail by Robert Burns in a 1794 letter to a contemporary; Burns describes how he had much difficulty coming by the instrument, and notes that it has six or seven fingerholes on the top, one on the back, and is played with a single reed ("oaten reed") unfixed to the instrument but held by the lips.

Musical ensemble: A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name.  Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra.  Some music ensembles consist solely of singers, such as choirs and doo wop groups.  In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers.  In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet).  Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds and percussion instruments, or the concert band, which uses brass, woodwinds and percussion.

Music lesson: Music lessons are a type of formal instruction in playing a musical instrument or singing.  Typically, a student taking music lessons meets a music teacher for one-on-one training sessions ranging from 30 minutes to one hour in length over a period of weeks or years.  For vocal lessons, teachers show students how to sit or stand and breathe, and how to position the head, chest, and mouth for good vocal tone.  For instrument lessons, teachers show students how to sit or stand with the instrument, how to hold the instrument, and how to manipulate the fingers and other body parts to produce tones and sounds from the instrument.  Music teachers also assign technical exercises, musical pieces, and other activities to help the students improve their musical skills.  While most music lessons are one-on-one (private), some teachers also teach groups of two to four students (semi-private lessons), and, for very basic instruction, some instruments are taught in large group lessons, such as piano and acoustic guitar.  Since the widespread availability of high speed.  low latency Internet, private lessons can also take place through live video chat using webcams, microphones and videotelephony online.

Instrument Schedule: In theatrical productions, an instrument schedule is a listing of all the lighting instruments and information about them used in a show.  The instruments are organized by their position on-stage, and is the distinguishing characteristic between an instrument schedule and a channel hookup or similar paperwork.  The instrument schedule includes all information about every instrument, including hanging location, instrument number, type, wattage, color, focus area, circuit, dimmer and templates, along with any additional information.  The variety of information included in an instrument schedule generally makes this more "complete" than other generated paperwork, and as such the schedule is often considered the "master" sheet.  The master electrician uses the information contained in the instrument schedule along with the light plot to direct the hanging of the instruments.

Khim: The Khim (Khmer: ឃឹម "Khum";Thai: ขิม, ];) is a stringed musical instrument that is from Persia, called Hammered Dulcimer or Cimbalon.  This Khim was introduced to Cambodia, Laos and Thailand from China, where a similar (though, since the late 20th century, usually larger) instrument is called "yangqin".  This instrument is also known as Santur in India.  It is played with two flexible bamboo sticks with soft leather at the tips to produce a soft tone.  This instrument can be played by either sitting down on the floor with the khim on the floor, or by sitting on a chair or standing while the Khim is on a stand.  The khim produces a bright and expressive sound when played.  It is made of wood, with brass strings that are laid across the instrument.  The Australian-born musician and vocal artist Lisa Gerrard specialises in the use of a khim hammered dulcimer, featuring its music on several albums and performing with the instrument live on tour.

Thavil: The thavil (Tamil:தவில்) or tavil is a barrel (drum) shaped heavy hand percussion instrument from Tamil Nadu.  It is used in temple, folk and Carnatic music, often accompanying the "nadaswaram".  The "thavil" and the "nadaswaram" are essential components of traditional festivals and ceremonies in South India.
