So! After a few hours of sweating over excel worksheets (don’t judge me, excel has never been my thing), I’ve finally managed to get together enough stats to make a proper post!
Statistics cover from 1x01 to 5x03.
When a character is marked as singing a “song” rather than a solo or duet, this could mean that they’re singing lead, or a couple of lines, or are just backing up a group number; it also accounts for solos and duets. So long as they sing, I’m counting them.
Some interesting points:
Blaine Anderson is the only character who has sung in every single episode of one season (Season 4). Surprisingly, there has been at least one episode each season in which Rachel Berry did not sing (season 1, Acafellas; season 2, Night of Neglect; season 3, The Spanish Teacher; multiple in season 4).
However, Rachel is the character who has sung the most episodes in a row over two seasons (from 1x04 to 2x16, a total of 35 episodes in a row, trumping Blaine’s 27 from 3x21 to 5x03).
Another interesting thing to consider when looking at these statistics is the number of songs, number of solos and number of duets related to how much plot each character has on the show. For example, Artie is the character with the second highest number of songs total, but has had less than half (subjectively) the amount of plot Rachel has been given.
As a matter of fact, Artie is the only character to have appeared in every single episode of Glee so far.
