Sololijn

Sololijn is a Dutch term that translates to 'solo line' in English. It is not a single canonical concept; in Dutch-language sources it can refer to distinct notions in music, manufacturing, logistics, or technology depending on the domain. The term is mostly used in industry jargon or as a descriptive label rather than as a formal name of a widely standardized concept.

In music, sololijn refers to a melody or melodic line performed by a single instrument or voice, as opposed to an ensemble line or harmony. In orchestration and score notation, a sololijn may be indicated for solo passages, sometimes marked with solo or primanotes.

In manufacturing or production planning, a sololijn can denote a dedicated production line configured to produce a single product or product family, allowing faster setup and more stable takt times, contrasted with flexible lines that handle multiple products.

In logistics or public transport, sololijn describes a direct service that runs without significant intermediate stops or transfers, connecting origin and destination more efficiently than a multi-stop line.

In software or audio production tools, a sololijn can refer to a solo channel or track selection, isolating a single track for editing or playback while muting others.

Etymology: from solus and lijn. The term is primarily found in Dutch-language contexts and is more common in technical or industry-specific usage than in everyday speech. Related concepts include solo, direct line, and monophony.
