My community band often plays in a nice auditorium, and my director has the horns on the last row on the side of the stage. Before the last concert, I noticed my sound went right back stage, but I was able to find a huge piece of wood to put behind me back stage. I was wondering if anyone has a much more portable suggestion as to what to use next time. I also think we'll need 2, since we now have a full horn section.
Thanks!

I've seen two types of sound reflectors used in horn sections:

(1) A spare metal music stand placed behind the bell of each member of the section. The angle of the music stand is adjustable to reflect the sound into direction you need it most.

(2) Home made reflectors foam core poster board. They were like a standing photo frame. The ones we used were about 33 " tall and about 22 inches wide at the base and tapering to about about 6 inches wide at the top. They were kinda cool because they didn't take up as much space as a music stand.

The music stand is definitely easier provided your band/orchestra has enough spare music stands for each section member.

I'm with Valerie on this one. When needed I will use a music stand. Tip the rack over 180 degrees and it iwll catch enough of your sound.

If you want to make a portable one you can use a large piece of cardboard, pasteboard, acryllic, etc. Just be sure to have three point of contact so it doens't fall while your playing.
