A long-string instrument is a musical instrument that is made up of a really, really long string that is stretched between two points, similar to a clothesline. The string can be made of different materials like metal or nylon, and it can be tightened or loosened to create different sounds.
To play the long-string instrument, you use your hands or tools like bows or mallets to create vibrations on the string. These vibrations travel up and down the entire length of the string and create different pitches and tones.
The cool thing about the long-string instrument is that you can make many different sounds at once by plucking or bowing different points along the string. This technique is called harmonics and it creates a beautiful and unique sound.
Long-string instruments are often used in experimental or avant-garde music and can be quite mesmerizing to watch and listen to!
