Question:

Are French Horns marching instruments?

Just wondering because all throughout elementary school and all through highschool the instructors told us that french horns were not marching insturments. *i don't play the french horn, i just saw during the rose parade people marching with them and it looked strange*

Best Answer - Chosen by Asker: Okay, here it is straight and front. French Horns are not marching instrumetns but people(like me) play the mellophone(Looks like a overlarge trumpet). They can be tuned different on the same, depends on make. The mellophone I play is tuned differently than my french horn
