Come on Fran... you know you got about as much chance of getting Ian to agree with you as you have of getting Bush to admit he goofed in Iraq...

The thing is, training only goes so far... Sure, all 'competent' players (and teachers!) will have had some instruction in how to do LH bass, maybe even read it off a chart, but how many actually sit down (or stand up ) and DO IT, much of the time?

Theory, and instruction only get you so far. You want to develop as a LH bass player...? Do it constantly for several months. Turn OFF the arranger parts, just use the drums, and play LH bass, RH comp and solos. FOR MONTHS... THEN, you'll get a feel for it. Want to get it faster? Join a band, and HAVE to do it every night!

You MIGHT have got some instruction in this IF you were lucky enough to a) get a good teacher and b) actually get enough time with them that they got around to walking basslines (remember, a lot of the adults here get instruction on their arranger, NOT a full piano), but it isn't exactly a skill that the average player gets to grips with until he has been taught for several years.

And you look at most classical music, the LH does NOT play the bassline... It plays a combination of bass notes, arpeggiation, chording and high end stuff, too. About the only time you see a 'pure' bassline is a two part Invention. Not exactly the best practice for playing a bassline in a band!

The thing we have to try and remember, here, is that this is NOT a 'pro' forum. Many of the members here may have had VERY little formal training. Some are still limited to One Finger Chord mode Advice needs to be offered that can be of benefit to a wide range of skill levels. It isn't of much help to say to someone that asks about how to do something that "Left hand bass comes naturally to any competent piano player..."

Tell me this isn't what you say to YOUR students when they ask a question, Ian...
