Join a marching band
Where can I do this?
Are the costs to get started high or low?
Would I be doing this in a group, in a couple, or on my own?
Are there physical requirements that might make it difficult for me to participate?
Requires the ability to play an instrument well!
So what's it all about?
Joining a marching band as an adult is a little more difficult, but it's not impossible!
There are semi-professional bands like the Chicago Brass Band and the Brass Animals that audition for new members, as do Windy City Winds. These are not all technically marching bands... but you get the idea. They exist if you are prepared to do some searching.
The Lakeside Pride Music Ensembles does not require auditions. Their website states that "All members and friends of the LGBTQ community are welcome to perform with us. About a quarter of our membership are straight, cisgender allies."
