When composing for the piano, I often find myself writing a lot of sudden soft notes. I need an accent mark that suddenly softens notes. From my knowledge (and searching the web), I can not find any accent markings to soften a note. I have found many accent notes that emphasises a note and makes them louder (marcato) - but none that makes them softer.
I'm really suprised that I haven't found any accent markings for sudden soft notes. What can I do to write something like that? I really don't want to write 'subito P' over every note I want to soften. (Playing notes suddenly soft is one of my favorite things to write, so I use it a lot in my compositions.)
