I am a musician myself, mainly playing piano and marimba. Up till now, I did not do much performing, mostly playing by myself or in front of family and close friends, as well as playing in an orchestra. However, more recently, I have been asked to perform on a few public events.
However, I have no idea how much money to ask for a performance.
Of course, this seems like a subjective question at first glance, but I am sure that some of the professional musicians out there have some knowledge on what is considered to be a 'fair' price, both for the performer as for the person creating running the event, and what circumstances have an influence on this price (one I can think of, for instance, is travel expenses but there must be much more).
So the question:
How much money is considered a reasonable price for a musical performance? What kind of circumstances have an influence on this price?
