I've seen certain peices of music reach a quad-f. In other words, sing as loud as your voice can while still sounding musical. As for the technical names for those two, they are: Fortisisimo Pianisisimo For any additional F or P added, simply add an extra -si- where appropriate.
I know that, however I did not feel like putting in any extra things to the poll, so I decided to just put it as Forte on and Piano on meaning the addition of an extra letter to the dynamic.
I usually like songs that go from pp to ff then back to pp, or something similar like that. Like Symphony 7 Movement 2. Or if it is done suddenly, like the Soviet March in Red Alert 3
Yay people who music as much as me xD I'm part of a really difficult choir so I learn a couple dozen pieces of music per year of school. I like music that stays relatively quiet and builds up A LOT of tension in the ways the chords are structured, which leads into one section (about 2/3rds of the way through the song) that is noticeably louder and releases the tension, followed with a quiet ending that has a sense of finality.
I love MF because my loud ass hands can't play anything quieter than piano properly and are too weak to play anything forte or louder. (on piano) On a completely unrelated note, Bflat major is my favorite key and it makes me so happy and F major comes in a close second c:
Forte and Mezzo Forte for me. Forte for drums bc I hate playing drums quietly. Mezzo Forte for viola bc I like to play somewhat loud just not too loud.
