Professionalism, Professionalism, Professionalism!
I cant stress this enough. Bottom line, there are a lot of talented musicians out there. As a matter of fact, only a fraction of that talent is required for a performance. However, there are not a lot of musicians that will not return phone calls, text, and emails in a timely manner. There are not a lot of musicians that will not show up on time to rehearsals and church service/gigs. There are a lot of musicians that will not learn songs like they are supposed to. There will be a lot of musicians who will have a bad attitude at gigs. You want to stand out? Be talented AND professional. Every interaction with another person is a possible audition for a gig.
