Lengthy Musical Dynamic Terminology
As a long-time musician (long-time for me, because I am rather young), I have come across two musical terms that are believed to continue into infinity. Forte, the term used in place of loud, can continue on forever by subtracting the ending vowel and adding the suffix iss, finally ending in imo. With every iss added, the volume raises, and does not include the imo at the very end. Of course, the louder the noise becomes, the closer to a planetary combust, but we can only hope that the music in question sounds good. Anyway, another term is piano, suggesting the exact opposite: a quieter volume. The suffix remains the same, and the longer it becomes, the softer and closer to absolute silence coming from the instrument being used.
