When I’ve got something close to a full sentence I google that and the Wikipedia article usually comes up.
I would consider googling a whole sentence to be "cheating" but you do you (honestly, meant in a genuine and entirely non-snarky and non-PA way, it really doesn't matter how individuals decide to play the game 🙂).
But, realistically, without googling it is really difficult to solve. I got Chopin really quickly but without google, or an encyclopedia, I would never have got his first name. It's just not something that I know. Even when I googled it, I was somewhat surprised that I didn't think, oh of course it's Frederic. If I ever knew, it was completely forgotten.
On the other hand, it could well have been a composer that I had never heard of - there are thousands of people on wikipedia that I don't know about. Once I had established something along the lines of it being a Polish composer, known for piano compositions, I would probably have been happy to google to for suggestions.
