Recent research has shown that different musical instrument sounds have strong emotional characteristics. It has also shown how these emotional characteristics change with different pitch and dynamics for the piano and bowed strings. This work differentiates the distinctive emotional characters of the brass instruments, and investigate how pitch and dynamics influence their characters. We conducted listening tests where listeners compared the brass instrument sounds pairwise over ten emotional categories. The emotional characteristics Happy increased with pitch. Heroic, Romantic, and Comic generally increased with pitch in an arching shape that peaked at C5 and decreased at the highest pitches. C alm, Mysterious, and Shy are also in arching shape but peaked at C3. Angry and Scary was somewhat U-shaped and especially strong in the extreme high register. Sad decreased with pitch. In terms of dynamics, the results showed that Heroic, Comic, Angry, and Scary were stronger for loud notes, while Romantic, Calm, Mysterious, Shy, and Sad were stronger for soft notes. These results help orchestrators and composers make the jump from knowing a particular pitch is technically possible on an instrument, to
understanding how its pitch register shapes its emotional character.
