 Next to influence on other bands sounds, several tribute efforts have been made. The String Quartet Tribute has created several Tool tribute albums, the first of which is Third Eye Open: The String Quartet Tribute to Tool (2001). Tool songs are arranged for classical music string instruments (violins, viola, cello and a double bass) with at least three musicians. The lack of percussion is sometimes countered with ""clicking"" col legno and other bowing techniques. Tool's songs are mostly multi-sectioned, and the band's sophisticated grasp of harmony allows for an interesting instrumental interpretation. 

 Metamorphic: The String Tribute to Tool Volume 2 (2003) is performed by two groups of musicians, including the group from Third Eye Open. Other String Quartet Tribute titles include: Finding Beauty in the Dissonance: A Piano Tribute to Tool, Chamber Made: The Baroque Tribute to Tool, Anotomica: The String Quartet Tribute to Tool, and The String Quartet Tribute to Tool's Ænima. 

 Other tributes to Tool include: A Gothic Acoustic Tribute to Tool, Tribute to Tool played by various rock artists, and Rockabye Baby: Lullaby Renditions of Tool."
