| description =Girls Logic Observatory are a Touhou arrangement circle who's music is primarily arranged and performed by sole member {{テラ}} who initially arranged primarily vocal Rock but has since branched out to include arrangement styles such as Jazz, Salsa and Pop. Vocals for the circle are notably contributed by both male and female vocalists, {{テラ}} himself sang on every album released by the circle up until the release of their third full album [[Reversible Negophilia]] in 2014. Releases by the circle regularly feature female vocalist {{咲子}} who is the circle's longest running recurring vocalists having debuted on the circles first mini album [[over knowledge]] in 2012, female vocalist {{うきね}} who debuted on the circle first full album [[Like a Retrospective]] in 2013 is another regular vocalist along with male vocalist {{保科}} who debuted on the circles fourth full album [[Hollow Masquerade]] in 2015. In addition to {{テラ}} and the circle's group of recurring support vocalists there are also a number of guest vocalists who contribute on full length albums, noteworthy past guests included {{ななせ}} of [[じゃねっと亭]], {{イチ}} of [[少年ヴィヴィッド]] and 556t of [[回路-kairo-|Kairo]] while as of 2016 vocalists {{あやぽんず＊}} of {{森羅万象|link}} and {{ななひら}} of [http://confetto.chu.jp/ Confetto] have made regular appearances.

Nearly every album released by the circle notably features unlisted bonus tracks, these tracks most commonly include off vocal versions of the album's vocal tracks in addition to a commentary track narrated by {{lang|ja|テラ}} himself discussing the specific album's tracks or concept. All of the circle's discography has been neatly divided into either singles, mini albums, full albums or collaboration albums. singles and mini albums primarily feature vocals by the circle's group of regular vocalists and feature tracks that often end up being re-recorded for later full albums. Full albums released by the circle notably feature a number of guest vocalists both male and female in addition to the circle's regular cast of support vocalists and will often feature new material in addition to re-recordings/re-masters of tracks from earlier mini albums and singles. Collaboration albums released by the circle often feature new material by the involved circles, re-arrangements or covers by the circles of each others past works and new collaborative material.
