bassrange

Bassrange is a term used in music production and acoustics to refer to the lower part of the audible spectrum that carries bass content. In common usage, it encompasses roughly 20 Hz to 250 Hz, where fundamental tones of many bass instruments reside and where much of the perceived warmth and fullness of sound originates. Some contexts extend the upper boundary to 500 Hz to include bass presence and body, but sub-bass and most low-end fundamentals remain under 250 Hz.

In musical notation, the bass range is associated with the bass clef and lower-register instruments such as the bass guitar, double bass, and left-hand piano parts. The explicit pitch range depends on instrument tuning, but the practical bass range is characterized by low frequency content rather than high treble content.

In recording and mixing, handling the bassrange involves microphone choice, direct inject for bass instruments, subwoofers, and low-end frequency management. Engineers often use high-pass filters on non-bass tracks to prevent low-frequency buildup, while using sub-bass or dedicated subwoofers to render frequencies below around 60 Hz. Sidechain compression and multiband processing are common tools to control bass energy without choking other elements.

In psychoacoustics and listening contexts, bassrange perception depends on room acoustics and the listener's hearing. Strong low-end content can dominate perceived loudness on compact speakers, so engineers often balance bass with mids to preserve clarity. The term’s usage is technical and contextual, varying across genres, equipment, and production workflows.
