Short version
How would I notate a repeat and fade in a music sheet, for the entire piece? Is there a standard way to do it?
Long version
I've been transcribing a piece of music of a SNES game, and like many of its contemporaries it loops at the end to keep the music going.
Since there is no actual end, I'm thinking of having it fade out as a third loop begins, or the second finishes. And that's actually what it does from the OST files I have available. The piece loops once, and then fades at the end of the second loop. Because of this I added a Da Capo al Fine, but I'm at a loss as to how to represent the fade out of the third loop, other than explicitly writing "Fade out after/before finishing the second loop".
How can this be notated?
This is what I have right now of the (incomplete) transcription, from this piece. In case the link dies, it's the Town Theme, from Illusion of Gaia.
