People of YC lend me your ears!

What is the instrumentation on this , especially with regard to the start? (the vid comments are not mine)

I guess, muted trumpets with cimbal, and something like a rattle, and then a soft clarinet

Sounds like muted trumpet, sustained cymbal, and a piano playing the notes c# d d# and e with the sustain pedal down? then is it a bass clarinet leading to the next section?

I havent a clue about the next bit so I wont say, sounds brassy and brass confuses me :(

Lots of lovely trombones!

trumpet with straight mute

(almost certainly synthesized) clarinet

possibly some sort of sustain pedal effect on a piano

trombone

(possibly synth) tuba or dbl bass

sus cymbal roll

bowed sus cymbal

A flute at the end, and I think the supporting brass does have a french horn, although I am not sure about that. It could be all trombones too.
