[This
question](https://japanese.stackexchange.com/questions/2738/%e3%81%a7%e3%82%82-demo-
versus-%e3%81%91%e3%81%a9-kedo-to-mean-but) covers the difference between でも
and けど for "but", the difference being that でも can be used at the beginning of
a sentence. But けど and が are used in very much the same way, syntactically.
What exactly is the difference between these two expressions?

question
word-choice nuances conjunctions
けど vs. が for "but" conjuction
I think that が is disjunctive while けど is concessive. That is to say that が
may connect two disjunctive (disconnected) parts, while けど not just connects
the two but introduces the succeeding clause as a circumstance that might be
expected to preclude the action of the main clause but does not.

I think the term "disjunctive" is a superset of "concessive". That is to say
that "disjunctive" includes "consessive".

answer
```

    今日はサッカーをして疲れたけど楽しかった。
    今日はサッカーをして疲れたが楽しかった。
    
```

```

    去年は遊びまくった。けど、成績は落ちなかった。
    去年は遊びまくった。が、成績は落ちなかった。
    
```

```

    ご飯食べるのはあとにしよう。おなかすいたけど。 
    ご飯食べるのはあとにしよう。おなかすいたが。
    
```

By comparing these sentences, "けど" appears to be softer and more common in
informal speaking. "が" delivers a sense that the speaker/writer is assertive,
often used by a person in a higher position or in formal writing.
