1. Here are levels of loudness that musicians use:symbolpppmpmffffwordpianissimopianomezzo pianomezzo fortefortefortissimomeaningvery softsoftmoderately softmoderately loudloudvery loudWhat would fff mean? ---------- ppp?2. Suppose there is an increase of 6 decibels from one level to the nextso that music played at the piano level of sound would have a readingof 6 decibels more than the music played at the pianissimo level andso on. How many more decibels would the ff level be than the pp level?_____ How 'many mOre decibels would the fff level be than the ppplevel? Can you tell how many times louder the p level isthan the ppp level?3. Guess the decibel readings for these sounds:soft recorded musicloud recorded musiclive symphony (very loud)decibelsCompare your numbers to those of a classmate, and check with yourteacher. Add this information to the chart on Numbers for Sounds.4. Two other musical symbols that control sound are-===--=crescendo(gradually increasingin loudness)anddecrescendo or diminuendo(gradually decreasing ordiminishing in loudness)What two symbols do they remind you of in mathematics?319
