Synonyms for "sympathetic strings" include "resonating strings," "auxiliary strings," and "sympathetic harmonics." Sympathetic strings are additional strings found on some stringed instruments, such as sitars and sarods, that vibrate in resonance with the primary strings, creating a fuller and richer sound. These strings are typically strung beneath the main strings and are not intended to be played directly. They add depth and dimension to the music, enhancing the harmonics and creating a more complex and nuanced sound. While the term "sympathetic strings" is commonly used, these other synonyms describe the same musical technique and can be used interchangeably.
