Sorry for butting in uninvited, but: if you are interested in Hans Zimmer's Interstellar approach, I strongly suggest checking out the music sheet! There are transcriptions in Musescore you can listen to in real-time and adapted to different instruments. See this for example: https://musescore.com/user/30188642/scores/6873032 I don't know if this is the score you were talking about, I couldn't find one called Mountain, this one is mostly piano (the second half adds strings and other instruments, pretty cool stuff).
Not a problem at all! I'm just super happy you are taking such an interest and that you are being so helpful, that is super cool! :)
I am afraid that I can't read music that well, because I'm not trained in theory- but the fact that you can listen to these pieces at the same time might make it a really good learning tool! So thank you so much for sharing that! I looked around at the site and I found the piece I was refering to if you are interested:

I think it is only arranged for piano in this version though! Still a great piece! :)
