With a length of two minutes and 54 seconds, "Thirr" was written and composed by Elvana Gjata herself and produced by Macedonian producer Darko Dimitrov. Serving as the first single in over a year after "Me tana", Gjata had been absent from the music industry following her participation in the 58th edition of the annual Festivali i Këngës. "Thirr" is musically an Albanian language "emotional" ballad incorporating "melancholic" and "sensual" elements in its notes reminiscent of Gjata's second extended play "3". Lyrically, it touches on a past and painful relationship, in which Gjata sings about a love interest who she put at the centre of her world, but who didn't show up for her.
