Two answers required. These two words name a “sonata” by Giovanni Gabrieli known for its precise specification of two groups of instruments. Bartolomeo Cristofori invented an instrument whose name is a portmanteau of these two words, which was later made obsolete by John Broadwood. Beethoven’s Pathetique (10[1])sonata begins with a Grave (“GRAH-vay”) C minor chord marked by these two words. Neither indicates (10[1])a vocal range, but prefacing these words with “mezzo” indicates a (10[1])subtler effect than these words alone. Adding (10[1])the suffix “issimo” to each of these two words results (10[1])in double-lettered dynamics, while these two words are represented as (10[1])single letters. For 10 points, name these two Italian words meaning “soft” and “loud” in music. ■END■
