It might be as simple as this PianoTweet.
A few notes, climbing up, crawling a bit and falling down.
Lasting a few seconds and then it’s gone.
Like a leaflet falling from the autumn tree.
It’s born, it grows, it lives for a while, it falls down and it dies.
From the fallen leaflet new life will be born.
Did you ever watch
how the leaflet
follows certain patterns and
almost predefined traces?
