The last Hawaiian O’O bird was recorded in 1986.  When the person who recorded it rewound the tape to listen to it hours after the bird had flown away, the excited bird immediately flew back expecting to find another of his species.

I wrote this music when I heard that story.

I used an app called KeyFinder to get the key of the bird-song. I used HookTheory to find the most popular chord progressions in that key and output the basic structure to MuseScore to finish it up. Several riffs are purely my own, but I can’t say I actually “composed” anything. It was more like I “put it together”.
