Last month, I visited a school of dance with a number of other composers from my university, to meet students there and explore possible future collaborations. I had misunderstood how the meeting would take place, and so I only realised I'd have to give an informal presentation about my music when I was already at the train station.
I'm an okay public speaker but nervous about presenting on my music, but the hastily-improvised presentation went really well, I got a great response from the dancers, and met several people who expressed an interest in working with me in the future.
I'm feeling more confident about my presentation skills, my ability to communicate about my music, and my music itself as a result.
As in Joshua Blaine's original description (below), but may be used to brag about things you've accomplished either this month (December) or the previous one (November), assuming that you haven't brought it up in any earlier Monthly Bragging Thread.
