It seems to be that there are a few basic right-hand playing styles or techniques that most bassists use: 1. Picking notes with the index & middle fingers 2. Playing with the thumb only 3. Playing with a pick 4. Slap & slap variations using a combination of thumb and fingers 5. Fingerstyle playing (which also may involve use of the thumb) There are obviously lots of variations on the above (e.g., Jamerson's single-finger version of #1), but generally this would seem to capture most of the options. I'm curious as to which style or styles have been favored by famous bass players both today and in the past. Which players have used picks? Which their thumbs? And is there any "standard" that's used by a large majority of players? Can anyone help fill the gaps in my historical knowledge?
