Hi Kris,
I would guess the notes are heard a second apart. They do not slide into each
other, they are distinct. It is definitely a “dusk” event, never hear it
during the daytime.
The Varied Thrush aren’t here this time of year. And their note is one that
tonally slides. I like to think of them as a “falling star” note.
I have Black-capped and Chestnut-backed Chickadees here all day long and year
‘round, but I’ve never seen a Mountain Chickadee here. I sure appreciate your
writing and I’ll try again this evening to record the song.

Can you tell us more about the pitch and the pace between the notes? In
addition to the varied thrush that was mentioned maybe a mountain chickadee?
Both birds seem to have the first two notes you mentioned but the third note
isn't quite right.

I live in SW Portland at the 600’ elevation above the Portland Zoo, near the
Sylvan bridge. As evening begins its close of light, I can hear a bird that
descends the major scale, one note at a time (not a tonal slide). Playing it
on my piano, it is “G”, “E”, “C”.
I’ve spent hours listening to all the sounds of my regular visitors (easily 40
species) at Cornell Lab. There are no sound recordings that match.
Neighborhood sounds (raucous outdoor games, for example) preclude my ability to
record this bird. When I do, I will share!
