Gradual dynamics & functionality


So I have a question about the gradual dynamics (cresc, dim, etc.).

I’m wondering if I for example have a stem with “piano”, and then I decide to put a cresendo line over a complete bar in that stem, after the cresendo marking is done, will the dynamic return to “piano” automatically or do I need to put a “p” after the cresendo to reset the dynamic to it’s previous state? I am also having this question for the other types of gradual dynamics.

Thanks in advance.

You’d need to put a p. And for the sake of visual clarity, if it were immediately following the crescendo, a “sub. p.”
