History of the violin also apply sonic effects. Electric violins may have four strings, or as many as seven strings. Since the strength of materials imposes limits on the upper string, it is usually tuned to E5, with additional strings tuned in fifths below the usual G3 of a typical four-string violin. The five-string electric violin shown in the gallery below was built by John Jordan in the early 21st century, and is tuned C G D A E.

String (music) longitudinal force increases with the square of the pulse amplitude, so the differences diminish with increasing amplitude. The elastic (Young's) modulus for steel is about 40 times greater than for nylon, and string tensions are about 50% greater, so the longitude and transverse force amplitudes are nearly equal. Tuning a stringed instrument such as a guitar to pitch puts the strings under a large amount of strain, which indicates the amount of stress inside the string. Stress is relative to the stretch or elongation of the strings. As the string is tuned to a higher pitch, it gets longer and
