- A gender based around cellos, their aesthetics, and at the core, cello music and sounds. Since every instrument can be made to produce different kinds of sounds, this could be a diverse gender experience, but the general aesthetic of cello music, deep and rich tones among other musical aesthetics, is the core of this gender.
- A subset of genderpiano where someone's gender is affected by playing the cello. One may feel their gender more strongly or feel a different gender/gender identity entirely when playing or listening to the cello. For example, one may be a demiboy normally, but be juxera when playing to and/or listening to the cello.
Someone who is celligender could also be both of those definitions as well as either one of them.
The term celligender was coined as part of a series of new musicagenders based on instruments on March 8, 2021 by FANDOM user Reign of the breadsticcs.
The celligender flag was also designed by Reign of the breadsticcs on March 8, 2021. The brown/golden color scheme of the flag represents the traditional colors of cellos, and the deep shades of each color represent the deep, soulful tones most commonly associated with cello music.
