The erhu (Chinese: 二胡; pinyin: èrhú; [aɻ˥˩xu˧˥]) is a Chinese two-stringed bowed musical instrument, more specifically a spike fiddle, which may also be called a Southern Fiddle, and is sometimes known in the Western world as the Chinese violin or a Chinese two-stringed fiddle. It is used as a solo instrument as well as in small ensembles and large orchestras. It is the most popular of the huqin family of traditional bowed string instruments used by various ethnic groups of China. As a very versatile instrument, the erhu is used in both traditional and contemporary music arrangements, such as pop, rock and jazz.

The pipa, pípá, or p'i-p'a (Chinese: 琵琶) is a traditional Chinese musical instrument belonging to the plucked category of instruments. Sometimes called the "Chinese lute", the instrument has a pear-shaped wooden body with a varying number of frets ranging from 12 to 31. Another Chinese four-string plucked lute is the liuqin, which looks like a smaller version of the pipa. The pear-shaped instrument may have existed in China as early as the Han dynasty, and although historically the term pipa was once used to refer to a variety of plucked chordophones, its usage since the Song dynasty refers exclusively to the pear-shaped instrument. The pipa is one of the most popular Chinese instruments and has been played for almost two thousand years in China. Several related instruments are derived from the pipa, including the Japanese biwa and Korean bipa in East Asia, and the Vietnamese đàn tỳ bà in Southeast Asia. The Korean instrument is the only one of the three that is no longer widely used.

The dizi (Chinese: 笛子; pinyin: dízi, pronounced [tǐt͡sɨ]), is a Chinese transverse flute. It is also sometimes known as the di (笛) or héngdi (橫笛), and has varieties including Qudi (曲笛), Bangdi (梆笛), and Xindi (新笛). It is a major Chinese musical instrument that is widely used in many genres of Chinese folk music, Chinese opera, as well as the modern Chinese orchestra. The dizi is also a popular instrument among the Chinese people as it is simple to make and easy to carry. Most dizi are made of bamboo, which explains why dizi are sometimes known by simple names such as Chinese bamboo flute. However, "bamboo" is perhaps more of a Chinese instrument classification like "woodwind" in the West. Northern Chinese dizi are made from purple or violet bamboo, while dizi made in Suzhou and Hangzhou are made from white bamboo. Dizi produced in southern Chinese regions such as Chaozhou are often made of very slender, lightweight, light-colored bamboo and are much quieter in tone. Although bamboo is the common material for the dizi, it is also possible to find dizi made from other kinds of wood, or even from stone. Jade dizi (or 玉笛; yùdi) are popular among both collectors interested in their beauty, and among professional players who seek an instrument with looks to match the quality of their renditions; however, jade may not be the best material for dizi since, as with metal, jade may not be as tonally responsive as bamboo, which is more resonant. Dizi are often played using various "advanced" techniques, such as circular breathing, slides, popped notes, harmonics, "flying finger" trills, multiphonics, fluttertonguing, and double-tonguing, which are also common in similar instruments, such as the western concert flute and recorder. Most professional players have a set of seven dizi, each in a different key (and size). Additionally, master players and those seeking distinctive sounds such as birdsong may use extremely small or very large dizi.

The sheng (Chinese: 笙) is a Chinese mouth-blown polyphonic free reed instrument consisting of vertical pipes. It is one of the oldest Chinese instruments, with images depicting its kind dating back to 1100 BCE, and there are original instruments from the Han dynasty that are preserved in museums today. Traditionally, the sheng has been used as an accompaniment instrument for solo suona or dizi performances. It is one of the main instruments in kunqu and some other forms of Chinese opera. Traditional small ensembles also make use of the sheng, such as the wind and percussion ensembles in northern China. In the modern large Chinese orchestra, it is used for both melody and accompaniment. The sheng has been used in the works of a few non-Chinese composers, including Unsuk Chin, Jukka Tiensuu, Lou Harrison, Tim Risher, Daníel Bjarnason, Guus Janssen and Christopher Adler. Some believe that Johann Wilde and Pere Amiot traveled to China and brought the first sheng to Europe in 1740 and 1777 respectively, although there is evidence that free reed musical instruments similar to the sheng were known in Europe a century earlier.

The gu zheng (Chinese: 古筝; pinyin: gǔzhēng; lit. 'ancient zheng'), is a Chinese plucked zither. The modern guzheng commonly has 21, 25, or 26 strings, is 64 inches (1.6 m; 5.3 ft) long, and is tuned in a major pentatonic scale. It has a large, resonant soundboard made from Paulownia wood. Other components are often made from other woods for structural or decorative reasons. Guzheng players often wear a fingerpick made from materials such as plastic, resin, tortoiseshell, or ivory on one or both hands. There are nylon steel strings, steel strings, silk strings, etc., depending on the genre. Now, the most common guzheng is 21 strings guzheng. The high-pitched strings of the guzheng are close to the player, and the low-pitched strings are on the opposite side. The strings' order from the inside to the outside is 1 to 21. The guzheng is ancestral to several other Asian zithers such as the Japanese koto, the Korean gayageum and ajaeng, Mongolian yatga, the Vietnamese đàn tranh, the Sundanese kacapi, and the Kazakhstan jetigen. The guzheng should not be confused with the guqin, a Chinese zither with seven strings played without moveable bridges. The guzheng has gone through many changes during its long history. The oldest specimen yet discovered held 13 strings and was dated to possibly during the Warring States period (475–221 BCE). The guzheng became prominent during the Qin dynasty (221–206 BCE). By the Tang Dynasty (618–907 CE), the guzheng was perhaps the most commonly played instrument in China. The guzheng is played throughout all of China with a variety of different techniques, depending on the region of China and the time period. It has a light timbre, broad range, rich performance skills, and strong expressive power, and it has been deeply loved by many Chinese people throughout history. The guzheng is plucked by the fingers with or without plectra. Interestingly, among the 21 strings of Guzheng, although no strings are specifically assigned to play F or B, those pitches can be produced by pressing E and A instead, respectively. Most modern players use plectra that are attached to up to four fingers on each hand. Ancient picks were made of mundane materials such as bamboo, bone, and animal teeth or by finer materials such as ivory, tortoiseshell, and jade. Traditional playing styles use the right hand to pluck notes and the left hand to add ornamentation such as pitch slides and vibrato by pressing the strings to the left of the movable bridges. Modern styles use both hands to play on the right side of the strings. There are many techniques used to strike notes. One iconic sound is a tremolo produced by the right thumb rotating rapidly around the same note. Other guzheng techniques include harmonics (Fanyin) where one plucks a string while tapping it at the same time, producing a note in a higher octave. Many guzheng techniques have been borrowed from other instruments. For example, Lun is a borrowed technique. In Lun, all five fingers pluck on a string to produce a tremolo sound similar to the Pipa. Techniques can also vary in Northern and Southern China, producing different sounds and styles.

The yangqin (simplified Chinese: 扬琴; traditional Chinese: 揚琴; pinyin: yángqín) is a Chinese hammered dulcimer, likely derived from the Iranian santur or the European dulcimer. It used to be written with the characters 洋琴 (lit. "foreign zither"), but over time the first character changed to 揚 (also pronounced "yáng"), which means "acclaimed". It is also spelled yang ch'in. Hammered dulcimers of various types are now very popular not only in China, but also Eastern Europe, the Middle East, India, Iran, and Pakistan. The instruments are also sometimes known by the names "santoor" and "cymbalom". This instrument had an influence on the Thai classical instrument, known as Khim (ขิม). The yangqin was traditionally fitted with bronze strings (though older Chinese stringed instruments used silk strings, resulting in their, and the yangqin's, categorisation as a silk, or "si" instrument), which gave the instrument a soft timbre. This form of instrument is still occasionally heard today in the "hudie qin" (蝴蝶琴, lit. "butterfly zither") played in the traditional silk and bamboo genre from the Shanghai region known as Jiangnan sizhu (江南絲竹), as well as in some Cantonese music and Chaozhou (Teochew) music groups. The Thai and Cambodian khim are nearly identical in their construction, having been introduced to those nations by southern Chinese musicians. Since the 1950s, however, steel alloy strings (in conjunction with copper-wound steel strings for the bass notes) have been used, in order to give the instrument a brighter, and louder tone. The modern yangqin can have as many as five courses of bridges and may be arranged chromatically. Traditional instruments, with three or more courses of bridges, are also still widely in use. The instrument's strings are struck with two lightweight bamboo beaters (also known as hammers) with rubber tips. A professional musician often carries several sets of beaters, each of which draws a slightly different

The cello is a bowed (sometimes plucked and occasionally hit) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3. The viola's four strings are each an octave higher. Music for the cello is generally written in the bass clef, with tenor clef, and treble clef used for higher-range passages. Played by a cellist or violoncellist, it enjoys a large solo repertoire with and without accompaniment, as well as numerous concerti. As a solo instrument, the cello uses its whole range, from bass to soprano, and in chamber music such as string quartets and the orchestra's string section, it often plays the bass part, where it may be reinforced an octave lower by the double basses. Figured bass music of the Baroque era typically assumes a cello, viola da gamba or bassoon as part of the basso continuo group alongside chordal instruments such as organ, harpsichord, lute, or theorbo. Cellos are found in many other ensembles, from modern Chinese orchestras to cello rock bands.

The piano is a keyboard instrument that produces sound when pressed on the keys. Most modern pianos have a row of 88 black and white keys: 52 white keys for the notes of the C major scale (C, D, E, F, G, A, and B) and 36 shorter black keys raised above the white keys and set further back, for sharps and flats. This means that the piano can play 88 different pitches (or "notes"), spanning a range of a bit over seven octaves. The black keys are for the "accidentals" (F♯/G♭, G♯/A♭, A♯/B♭, C♯/D♭, and D♯/E♭), which are needed to play in all twelve keys. When the keyboard is pressed, the tightened strings inside are struck by coated wooden hammers. The vibrations are transmitted through a bridge to a soundboard that amplifies the sound by coupling the acoustic energy to the air. When the key is released, a damper stops the string's vibration, ending the sound. Most notes have three strings, except for the bass, which graduates from one to two. Notes can be sustained when the keys are released by the use of pedals at the base of the instrument, which hold the dampers off of the strings. The sustain pedal allows pianists to play movements, such as shifting hands from bass to treble range while sustaining a chord, enabling melodies and arpeggios on top.
