Hi Lady! I started a year ago at 62, same background as yours. Was able to start playing with cajun and bluegrass jam groups within three months or so but not terribly proficiently. Both those genres are a bit easier for getting started...basic chords and simple root-fifth base lines. After a year, I'm getting better with keeping a groove and incorporating lead up notes, passing notes and adding thirds. I also aspire to jazz. When I listen and look at the music, its pretty intimidating. You have to know your chord structure really well it seems to me and anticipate chord changes very very well. Try to find a cajun or bluegrass group. They just CRAVE having an upright bassist if they don't have one! It really fills out the sound so very well...I surprise myself! I sound crummy when I practice but in the groups, it sounds good and its fun! Keeps you motivated. Remember to practice every single day even if not for a long time. Its amazing that you can take a difficult passage and get better at it by struggling with it everyday. Big thing is to play with people! Can't describe how much fun it is. Our cajun group plays outside in a park by a pond in Ann Arbor Michigan in the summer...park goers listen, canoers listen, clap, sometimes dance. Summer breezes, sunsets, and playing upright bass...HEAVEN ON EARTH!!
