This string trio is a paraphrase: not only its name but its four-part structure and essential characters are derived from the eponymous poem by Lassi Nummi. In one respect, however, the music goes its own way: where Nummi has a sombre memento mori concluding each stanza, Heiniö's trio breaks into a song, a canto, which is broader every time.

Jousitrio on saanut nimensä, neliosaisen rakenteensa ja keskeiset karakterinsa Lassi Nummen runosta "Canzona". Mutta siinä missä Nummella jokaisen säkeistön lopussa kolahtaa synkeä memento mori, triossa puhkeaa esiin canto, kerta kerralta laajeneva laulu.
