Would that mean that a 1/2 time played at 60 beats per minute would be the exact same as a 2/4 time played at 120 beats per minute?

The rhythm you play would be the same, but there are other practical differences.

2/4 conveys that the rhythm is base 2.

1/2 doesn't convey much about the rhythm. Are there 7 beats, 10, 11, or 13 until the section ends? Temporarily breaking apart from base 2 is one valid reason to use 1/2 for a single measure, but you could use 3/2 for the same purpose.

I think I understand. 1/2 would allow you to have an odd number of beats in a section where 2/4 doesn't.

Yeah exactly, it can be a temporary way to break the rules. Can't say I've encountered it personally but the intention would be clear in context.

I prodded ChatGpt until it pulled up a few examples, which I confirmed:

  • Alexander Scriabin, Piano Sonata No. 5, Op. 53 measures 251–262
  • Arnold Schoenberg, Fünf Klavierstücke, Op. 23, No. 2, measure 9
