Recently started playing with a new bluegrass Band. New to me as they have played together for years.They heard me play with my current band and thought that I would be a great addition.However, One of the band members assumed that I could play all their songs by ear. But I couldn't. I need to learn a song first by seeing chord books, fake books or sheet music. At least long enough to learn the song. Am I a bad bass player for needing to hear and learn a song first? Only been at this three years and never played an instrument before.
