Final answer:
In Haydn's Trumpet Concerto, dynamics are described by terms like forte and piano, while terms like allegro and staccato do not describe dynamics.
Step-by-step explanation:
In Haydn's Trumpet Concerto, the dynamics in both the trumpet and orchestra parts can be described using terms such as forte (loud), piano (soft), crescendo (gradually getting louder), and decrescendo or diminuendo (gradually getting softer).
Terms that do not describe dynamics include allegro (a tempo marking indicating a fast speed), adagio (a tempo marking indicating a slow speed), and staccato (a style of playing notes in a detached and separated manner).
