 Njanji Sunji consists of twenty-four titled pieces and an untitled quatrain. Indonesian literary documentarian H.B. Jassin classifies eight of the works as lyrical prose, with the remaining thirteen as poems. None of the works in Nyanyi Sunyi (and indeed none of Amir's other works) are dated. At the end of the book is a couplet, reading "Sunting sanggul melayah rendah / sekaki sajak seni sedih", which American poet and translator Burton Raffel translates as "A flower floating in a loose knot of hair / Gave birth to my sorrowful poems".
