Twilight (also commonly referred to as Twilightsynth) is a subgenre of vaporwave, characterized by its moody, atmospheric sound and the notable use of soundfonts as primary instruments. These soundfonts, often originating from older workstations or dated video game systems, are used as expressive tools rather than purely nostalgic references, allowing for a wide emotional range across different works.

The subgenre was coined by Brazilian music producer Gabriel Eduardo, best known under his Windows96 moniker, and is most closely associated with releases such as Enchanted Instrumentals & Whispers, One Hundred Mornings, and Yes Da Da Da.

Since its initial mention, Twilight has expanded beyond a single release, appearing across multiple projects and being adopted by several artists, gradually forming a loosely defined yet recognizable stylistic identity within the vaporwave domain.
