Crossstrung

Crossstrung is a term that can refer to a specific method of stringing a musical instrument, most commonly a piano. In piano construction, crossstrung refers to the arrangement of strings where the bass strings are laid across the treble strings, forming an angle rather than running parallel. This differs from straight-strung pianos where all strings are arranged in parallel rows.

The crossstrung system allows for a longer string length in a more compact soundboard area, potentially leading to a richer tone and greater volume. The angled strings also contribute to a more even distribution of vibrations across the soundboard. This design became prevalent in the mid-19th century and is now standard in most grand pianos and many upright pianos. The crossing of strings requires careful engineering to ensure they do not interfere with each other and to optimize the transfer of sound. While the term is most often associated with pianos, similar principles of crossing strings for acoustic or structural reasons might be found in other stringed instruments, though "crossstrung" is primarily a piano-specific designation.
