noun + を + nounする vs noun の noun を する

Question

Are both of these formats interchangeable?:

noun の noun を する

noun + を + noun する

For example: I'm going to practice the piano on Monday

月曜日にピアノの練習をするつもりです

(noun の noun を する)

月曜日にピアノを練習するつもりです

(noun + を + nounする)

Do both of these sentences work and make sentence? Do they mean the exact same or do they emphasise words differently?

This question is about all uses of both "する formats".

Answer 1

I think the general answer to your question is "yes" (assuming the second "noun" is a する-verb noun), but I do think the flavor/meaning of the phrase changes. I expect the differences are roughly equivalent to English "I'm going to do some piano practice now" vs "I'm going to practice piano now".

In general I'd expect をする to have the connotation of "doing X", whereas with suru-verb noun + する (no を), you can more readily think of the noun+する as a single verb/word in its own right, at least in terms of translation.
