Hi Madeline,
I tried playing at our local airport one time. It was a very interesting experience! I played near one of the terminals where folks were waiting for their loved ones to arrive. I received a number of wonderful compliments, mainly for the calming nature of the music I was playing and also for the eclecticism of my music. (I play pop, light jazz, light classical, traditional and Contemporary Gospel music–something for almost everyone!) One memorable aspect of the event was that I remember being very much “in the zone” while playing and therefore was able to play with a lot of feeling and with virtually no small errors, which was wonderful for me.
