The phrase identifies a selection of extended-range instruments designed for guitarists seeking a broader tonal palette and increased creative possibilities. These instruments typically feature two additional strings below the standard six, often tuned to lower registers such as F# and B, or E and A. A practical example would be a guitarist using one of these instruments to play djent riffs or create thick, atmospheric soundscapes.
The significance lies in their ability to unlock lower frequencies and create complex harmonies unattainable on standard guitars. This capability has influenced genres like progressive metal, djent, and extended-range jazz. Historically, the development reflects a demand for increased low-end response and expanded sonic territories, allowing for innovative approaches to composition and performance. The augmented range facilitates both heavier rhythmic foundations and more intricate melodic arrangements.
