* Know the music. Go that extra mile and memorize your part. In addition, learn the other parts such as the drum groove, the keyboard, the guitar, the melody, the harmony, the vocal line, the lyrics. Be able to voice the chord progression of the song on your bass. In other words, REALLY know the whole song not just your bass part.
* Come prepared. Bring extra chords, tuners, strings, batteries, straps, stands, amps and anything else that may be necessary.
* Make sure your equipment is setup and operating properly. No buzzes or equipment issues/malfunctions should be tolerated.
* Have a press pack with biography, CD of your work, picture. At the very minimum have a business card with your contact info.
* Be on time! In fact be early. There is never a second chance for first impressions!
* Expect that you will be nervous. Learn how to handle and cope with this energy and use this energy to your advantage. There are many books on the subject, one I would recommend is, “The inner Game of Music” by W. Timothy Gallwey and Barry Green.
* Finally, once you get the gig, the work has just begun. Be professional and prompt and always go that extra mile to keep the artist happy.
