Scott Hansen (born February 7, 1977), known professionally as Tycho (/ˈtaɪkoʊ/ TY-koh), is an American musician, record producer, composer, and songwriter based in San Francisco.

[4][5] His music blends multiple stylistic components, including downtempo guitar, analogue synthesis, and ambient elements such as breathing and found sounds of weather broadcasts and dialogue.

[13] Hansen's music project Tycho is influenced by and has been compared to artists such as DJ Shadow, Ulrich Schnauss and Boards of Canada.

In Past Is Prologue, Hansen includes excerpts from broadcasts accompanied by atmospherics to capture a specific moment or mood.

His goal is to find the balance between the fluid nature of a live show with artists playing physical instruments and the precision and ability to stay true to the album of electronic music.
