If you are in a marching band and they play some complex music, it may be beneficial for you to purchase a music stand specifically for marching bands and specifically for your instrument.
There are a number of different types of marching band music stands and they are basically small clips that attach to your instrument so that you are able to be able to clip on your music. These clips are usually specific to the type of instrument that you have. If you play a brass instrument you will want to pick up the corresponding brass marching band music stand sometimes referred to as a "marching band lyres". The same goes for wood instruments.
These marching band lyres are indispensable when you are in the band and first learning the music. You will be able to march and learn your formations and at the same time have your music right there.
If you are need of a music stand for a marching band, you can often go to the school where you are playing and they will have a possible outlet where you can purchase these stands.
Now if you are a conductor for a marching band, you may want to get a stand to use during practice and before you memorize the music. These stands will need to be tall so that they can reach you on your stand or platform. But eventually you will need to get rid of the stand as you will not have the chance to use it during the time the marching band is on the field or in the parade.
