A keyboard instrument is a musical instrument which is played using a musical keyboard. The most common of these is the piano. Other widely used keyboard instruments include organs of various types as well as other mechanical, electromechanical and electronic instruments. In common language, it is mostly used to refer to keyboard-style synthesizers.Among the very earliest keyboard instruments are the pipe organ, hurdy gurdy, clavichord and harpsichord. The organ is without doubt the oldest of these, appearing in the 3rd century BC, though this early instrument—called hydraulis—did not use a keyboard in the modern sense. From its invention until the 14th century, the organ remained the only keyboard instrument. Often, the organ did not feature a keyboard at all, rather buttons or large levers which were operated by a whole hand. Almost every keyboard until the 15th century had naturals to each octave.

The clarinet is a type of woodwind instrument. The name derives from adding the suffix -et (meaning little) to the Italian word clarino (meaning a type of trumpet designed for high-register playing), as the first clarinets had a strident tone similar to that of a trumpet. The instrument has an approximately cylindrical bore, and uses a single reed.

Clarinets comprise a family of instruments of differing sizes and pitches. The clarinet family is the largest such woodwind family, with more than a dozen types, ranging from the (extremely rare) BBB♭ octo-contrabass to the A♭ soprano (piccolo clarinet). Of these, many are rare or obsolete (there is only one BBB♭ octo-contrabass clarinet in existence, for example), and music written for them is usually played on the common types. The unmodified word clarinet usually refers to the B♭ soprano clarinet, by far the most common clarinet.

The saxophone (also referred to as the sax) is a conical-bore transposing musical instrument that is a member of the woodwind family. Saxophones are usually made of brass and played with a single-reed mouthpiece similar to that of the clarinet. The saxophone was invented by the Belgian instrument maker Adolphe Sax in 1846. He wanted to create an instrument that would both be the most powerful and vocal of the woodwinds and the most adaptive of the brass, which would fill the vacant middle ground between the two sections. He patented the sax on June 28, 1846 in two groups of seven instruments each. Each series consisted of instruments of various sizes in alternating transposition. The series pitched in B♭ and E♭, designed for military bands, has proved extremely popular and most saxophones encountered today are from this series. Instruments from the so-called "orchestral" series pitched in C and F never gained a foothold.

The bansuri (Hindi: बांसुरी,Nepali: बाँसुरी, Marathi: बासरी Assamese: বাঁহি, Bengali: বাঁশি) is a transverse alto flute of Bangladesh, India and Nepal made from a single hollow shaft of bamboo with six or seven finger holes. An ancient musical instrument associated with cowherds and the pastoral tradition, it is intimately linked to the love story of Krishna and Radha, and is depicted in Buddhist paintings from around 100 AD. The Bansuri is revered as Lord Krishna's divine instrument, and is often associated with Krishna's Rasa lila; The word bansuri originates in the Sanskrit bans [bamboo] + sur [musical note]. There are two varieties of bansuri: transverse, and fipple. The fipple flute is usually played in folk music and is held at the lips like a whistle. Because it enables superior control, variations and embellishments, the transverse variety is preferred in Indian classical music

The tabla (or tabl, tabla) (Hindi: तबला, Marathi: तबला, Kannada: ತಬಲ, Telugu: తబల, Tamil: தபேலா, Malayalam: തബല, Bengali: তবলা, Punjabi: ਤਬਲਾ, Nepali: तबला, Urdu: طبلہ, Arabic: طبل، طبلة‎, Persian: طبل‎) is a popular Indian percussion instrument (of the membranophone family), similar to bongos, used in Hindustani classical music and in popular and devotional music of the Indian subcontinent. The instrument consists of a pair of hand drums of contrasting sizes and timbres. The term 'tabla is derived from an Arabic word, tabl, which simply means "drum." ^[1]

Playing technique involves extensive use of the fingers and palms in various configurations to create a wide variety of different sounds, reflected in the mnemonic syllables (bol). The heel of the hand is used to apply pressure or in a sliding motion on the larger drum so that the pitch is changed during the sound's decay.

Veena is a stringed instrument. It consists of a large body hollowed out of a block of wood. The stem of the instrument is also made of wood. The bridge is placed on the flat top of the body of the veena and the neck attached to the stem is usually carved into weird figure like the head of the dragon.

A gourd which is smaller than the rounded part of the body is fixed underneath the neck. Twenty one metallic frets are fixed on the stem by means of a resinous substance.

The veena has seven strings. Of them four are main strings that pass over the frets and are attached to the pegs of the neck. The other strings are used as side strings for rhythmic accompaniment. These strings pass over an arched bridge made of brass. They lie flat over the top of the body and are secured to the main bridge.

The santoor is an ancient stringed musical instrument native to Kashmir (India) and Persia. It is a trapezoid-shaped hammered dulcimer often made of walnut, with seventy two strings. The special-shaped mallets (mezrab) are lightweight and are held between the index and middle fingers. A typical santoor has two sets of bridges, providing a range of three octaves.

The Kashmiri santoor is more rectangular and can have more strings than the Persian counterpart, which generally has 72 strings. The santoor as used in Kashmiri classical music is played with a pair of curved mallets made of walnut wood and the resultant melodies are similar to the music of the harp, harpsichord, or piano. The sound chamber is also made of walnut wood and the bridges are made of local wood and painted dark like ebony. The strings are made of steel.
