Grief for the living comes without a funeral or any permission to feel it. They are still out there, moving through a day that no longer has room for you, and the wanting carries on regardless, ambushing you in a chord change or a familiar street.
There is nowhere to put it. The world expects you to be over it because nobody died, and yet the absence is total, a person-shaped hole you keep walking into in the ordinary places you used to share.
The music mourns openly, slow and heavy with absence. Long, aching lines, a lot of empty air, a groove that moves like someone walking home the long way to put off arriving.
This is the arc turning to grief proper, aching and unresolved. Play it when the loss has no ceremony and you need one anyway.
