一、古筝（Guzheng）
- 构造与发声原理
- 古筝是一种长而扁平的木制弹拨乐器。通常有 21 根弦（不过不同类型的古筝弦数可能不同），弦沿着琴身长度方向架在可移动的琴码上。古筝的琴身是中空的，起到共鸣箱的作用。当演奏者用义甲（通常戴在手指上）拨弦时，弦振动起来。这些振动传递到乐器琴身，使中空琴身内的空气振动，从而发出声音。可移动的琴码可用于调音，以实现不同的音高。
- 例如，在演奏像《高山流水》这样的传统中国乐曲时，拨弦会产生清晰悦耳的声音。琴身的共鸣放大并丰富了音色，使得能够通过音乐传达出高山的雄伟和流水的灵动。
- 演奏技巧
- 拨弦技巧：古筝演奏中有几种基本的拨弦技巧。“勾”（hook）技巧是用右手手指尖将弦向内朝手掌方向拨。“托”（pluck）技巧则相反，是用手指尖将弦向外拨。“抹”（wipe）技巧是手指尖在弦上做横向移动。这些技巧可以通过各种方式组合，产生丰富多样的节奏和旋律。
- 左手技巧：左手手指用于按弦以改变音高并添加装饰音。一个重要的左手技巧是 “滑音”（slide）。通过按弦并沿着弦滑动手指，可以实现音高之间的平滑过渡，为音乐增添抒情的特质。另一个技巧是 “颤音”（vibrato），左手手指轻微晃动弦，使音高产生波动效果，增强音乐的表现力。
- 音乐风格与应用场景
- 古筝适合多种音乐风格。在独奏表演中，它可以演奏具有浓郁民族风味的传统中国音乐，比如描绘自然风光或讲述历史故事的曲目。在合奏场合，它能与琵琶、二胡等其他中国传统乐器很好地配合。例如，在中国民族管弦乐队中，古筝提供丰富的和声背景，也能演奏旋律线条，有助于营造和谐且多层次的音乐织体。在现代音乐中，古筝独特的音色也被融入到各种音乐形式中，如电影配乐和流行音乐，增添了一份异域风情。

I. Guzheng
- Construction and Sound – production Principle
- The guzheng is a plucked zither with a long and flat wooden body. It typically has 21 strings (though there can be other numbers in different types), which are stretched over movable bridges along the length of the body. The body of the guzheng is hollow, acting as a resonator. When a player plucks a string with a plectrum (usually worn on the fingers), the string vibrates. These vibrations are transmitted to the body of the instrument, causing the air inside the hollow body to vibrate and produce sound. The movable bridges allow for tuning adjustments to achieve different pitches.
- For example, in a performance of a traditional Chinese piece like “High Mountain and Flowing Water”, the plucking of the strings creates a clear and melodious sound. The resonance of the body amplifies and enriches the tone, making it possible to convey the grandeur of mountains and the fluidity of water through music.
- Playing Techniques
- Plucking Techniques: There are several basic plucking techniques in guzheng playing. The “hook” (勾) technique involves using the fingertip of the right hand to pull the string inward towards the palm. The “pluck” (托) technique is the opposite, where the fingertip pushes the string outward. The “wipe” (抹) technique is a sideways movement of the fingertip across the string. These techniques can be combined in various ways to produce a rich variety of rhythms and melodies.
- Left – hand Techniques: The left – hand fingers are used to press the strings to change the pitch and add ornamentation. One important left – hand technique is the “slide” (滑音). By pressing a string and sliding the finger along it, a smooth transition between pitches is achieved, adding a lyrical quality to the music. Another technique is the “vibrato” (颤音), where the left – hand finger slightly shakes the string to produce a wavering effect on the pitch, enhancing the expressiveness of the music.
- Musical Styles and Application Scenarios
- The guzheng is suitable for a wide range of musical styles. In solo performances, it can play traditional Chinese music with a strong ethnic flavor, such as pieces that depict natural scenery or tell historical stories. In ensemble settings, it combines well with other traditional Chinese instruments like the pipa and the erhu. For example, in a traditional Chinese orchestra, the guzheng provides a rich harmonic background and can also play melodic lines, contributing to a harmonious and multi – layered musical texture. In modern music, the guzheng’s unique timbre has also been incorporated into various forms of music, such as film scores and pop music, adding an exotic touch.
II. Pipa
- Construction and Sound – production Principle
- The pipa has a pear – shaped wooden body with a short neck. It has four strings, usually made of silk or nylon – wrapped wire. The sound is produced when the player plucks the strings with the fingers or a plectrum. The body of the pipa acts as a resonator, amplifying the vibrations of the strings. The strings are attached to tuning pegs at the top of the neck, allowing for precise tuning.
- For example, in a performance of a traditional pipa piece like “Ambush from Ten Sides”, the initial pluck of the strings creates a sharp and penetrating sound. The body of the pipa enhances and projects this sound, making it possible to vividly depict the intense battle scenes and the changing moods of the music.
- Playing Techniques
- Plucking and Strumming Techniques: The pipa has a wide variety of plucking and strumming techniques. The “forward pick” (弹) is a basic technique where the fingertip of the right hand plucks the string outward. The “backward pick” (挑) is the opposite, plucking the string inward. The “roll” (轮指) technique is a more complex and characteristic technique of the pipa. It involves the rapid and continuous rotation of the fingertip to produce a sustained and flowing sound, similar to the effect of a trill.
- Left – hand Techniques: The left – hand fingers are used to press the strings to change the pitch and add various ornamentations. The “slide” technique is used to smoothly change the pitch by sliding the finger along the string. The “vibrato” technique, similar to that of other instruments, is used to add a wavering effect to the pitch, enhancing the expressiveness of the music.
- Musical Styles and Application Scenarios
- The pipa is a highly expressive instrument. In traditional Chinese music, it can play both gentle and lyrical pieces as well as powerful and energetic ones. For example, in the “Wen – style” (文曲) pipa pieces, the music is often slow, delicate, and full of emotional nuances, expressing themes such as love and longing. In the “Wu – style” (武曲) pieces, the music is more dynamic and intense, usually depicting battle scenes or heroic deeds. In ensemble music, the pipa can play a leading role or provide harmonic support, depending on the musical context. In modern music, the pipa’s unique timbre and playing techniques have also attracted the attention of many composers, who have incorporated it into contemporary musical works.
III. Guqin
- Construction and Sound – production Principle
- The guqin is a seven – stringed zither with a long and narrow wooden body. The strings are made of silk (traditionally) and are stretched over the body. The body is usually made of paulownia wood and has two sound holes, which help in the resonance of the instrument. When the player plucks the strings with the fingers, the strings vibrate and transmit the vibrations to the body. The air inside the body then vibrates through the sound holes, producing a unique and mellow sound.
- For example, in a performance of a traditional guqin piece like “Flowing Water”, the plucking of the strings creates a pure and clear sound. The resonance of the body through the sound holes gives the music a sense of space and tranquility, as if the sound of water is flowing in a secluded valley.
- Playing Techniques
- Plucking Techniques: The guqin has its own set of plucking techniques. The most basic is the simple finger plucking, where the player uses the fingertip to pluck the string. There are also more complex techniques such as “flick” (抹) and “hook” (勾), which are used to produce different rhythms and tonal colors.
- Left – hand Techniques: The left – hand fingers play a crucial role in guqin playing. The “press” (按) technique is used to change the pitch by pressing the string against the surface of the instrument. The “slide” technique is used to achieve a smooth transition between pitches, creating a melodious effect. The “vibrato” technique, similar to other stringed instruments, is used to add a wavering effect to the pitch to enhance the expressiveness of the music.
- Musical Styles and Application Scenarios
- The guqin has a profound cultural connotation. In traditional Chinese culture, it is often associated with the literati and their pursuit of artistic and spiritual refinement. The music played on the guqin is usually slow – paced, focusing on the expression of inner feelings and the pursuit of a kind of ethereal and tranquil artistic conception. In solo performances, it is a vehicle for self – expression and spiritual cultivation. In ensemble settings, it can also combine with other instruments such as the xiao and the sheng to create a more complex musical atmosphere.
IV. Ruan
- Construction and Sound – production Principle
- The ruan has a round – bodied shape with a long neck. It usually has four strings and a hollow body that acts as a resonator. The strings are made of nylon – wrapped wire. When the player plucks the strings with a plectrum or fingers, the strings vibrate and the vibrations are transmitted to the body, causing the air inside to vibrate and produce sound.
- For example, in a performance of a ruan piece, the plucking of the strings creates a mellow and full – bodied sound. The resonance of the body gives the sound a warm and rich quality, making it suitable for playing a wide range of musical styles.
- Playing Techniques
- Plucking Techniques: The ruan uses similar plucking techniques as other plucked instruments. The basic “pluck” and “hook” techniques are used to produce different notes and rhythms. There are also techniques like “roll” which can produce a continuous and flowing sound.
- Left – hand Techniques: The left – hand fingers are used to press the strings to change the pitch and add ornamentation. The “slide” technique is used to smoothly change the pitch by sliding the finger along the string. The “vibrato” technique is used to add a wavering effect to the pitch, enhancing the expressiveness of the music.
- Musical Styles and Application Scenarios
- The ruan is a versatile instrument. It is used in traditional Chinese music ensembles to provide harmonic support and play melodic lines.
