Instruments within the realm of steel guitar, employing foot-operated levers and knee levers to alter pitch, represent a unique facet of stringed musical expression. These sophisticated devices facilitate the creation of characteristic gliding tones and complex harmonies, setting them apart from conventional guitars. They are built for the purpose of creating many complex harmonies and melodic textures which standard guitars cannot.
The use of these instruments has had a substantial influence on country, Hawaiian, and Western swing music, enriching these genres with its distinctive soundscapes. The capacity to smoothly transition between chords and to generate portamento effects contributes significantly to its expressive potential. Its historical development is interwoven with the evolution of American roots music, gaining prominence in the early to mid-20th century.
