Hm..
https://en.wikipedia.org/wiki/Reinhold_Gli%C3%A8reBecause of the rising strings at the end the push/pull/sighing idea.
There's also a change of style... And the orchestration isn't filled out... Maybe a piece from a younger composer, earlier time in their career?
It's an orchestra, symphony... full, not just strings... Although I don't hear much brass or percussion... Maybe it's something smaller... Small ensemble...
Yes... It doesn't sound like a full orchestra. If it is a full orchestra, the composer isn't making use of that. It doesn't have a broad sound at all. I'm listening to orchestra clips. They're very different.
Could be a piece for a student orchestra...
It's very melodic. Easily accessible.
The harmonies would give some indication. And all that ornament work in the melody.
Or... It's just recorded imperfectly. Hm. Or... large orchestra but not using a lot of it... That sounds like Mahler. I still hear Russian though. Maybe it's another composer from that area...
I'm still leaning toward Gliere or one of those guys.
Small ensemble... chamber group... Smaller than an orchestra, but bigger than a sextet... Strings, clarinets.... What else is there? Possibly a French horn? Possibly a sax? A sax would be great to narrow down the time.... Unless it was an arrangement.
If it was on an online radio stations, I'd lean toward classical or movie music, not a student orchestra piece. A local radio station might play a student piece... I don't see an online radio channel doing that.
