What is marching version of french horn?

A marching version of a French horn is designed for use in marching bands and outdoor events. They are typically smaller and lighter than regular French horns to make them easier to carry and maneuver while marching.

Marching French horns have a more pronounced forward bell and narrower bore to help with projection and minimize wind resistance. They may also feature adjustable leadpipes and bell flares to accommodate different playing styles and environments.

Marching French horns can be made out of brass or fiberglass, and are often lacquered to protect the instrument from the elements. Some models may also feature a removable leadpipe or bell for ease of transportation.

In terms of playing technique, marching French horns require a slightly different approach than regular French horns due to their more compact size and forward projection. They are typically played with a stronger, more focused sound and a higher degree of volume and projection to cut through the noise of a marching band.
