I've actually done that to. I used to do it as much as my ring-middle excercise, but found it wasn't as beneficial with regards to ring-middle independence. Thats one of the most difficult aspects of three finger playing for me.
Its not about finger independence, its about finger interaction.
We like to build certain finger sides up to deal with problems, sort of get them with the flow, then work in the interaction.
I am a big believer in working on individual fingers but normally that is because they have a weakness that needs to be addressed.
Instant results is not the name of the game here, better results that last and are healthy is what we really should be looking for.
Fingers are primarily joints, so they have a shelf life, so they need to be looked after. Playing till we are tired is not good health, that's when injury occurs, or putting in the "pain for the gain" again injury is not far behind that one.
The world is full of Joggers who now realise there feet, knees and hips have been damaged in a pursuit they thought was beneficial.
Musicians suffer in the same way to the extent some physicians that deal with musicians can tell the instrument used by the injury presented to them before the patient even utters a word.
So take care with what you do with the hands and remember the rule "Damage comes from misuse and over use"
I guess I'll be a dissenting voice here.
(I posted this in a different thread a couple of days back)
There really isn't a reason to play with 3 fingers for even the fastest basslines.
No... your point is a great one, but its not about speed and that is where the misunderstandings come in. If you want speed use a pick, most metal guitarists use one and they have no problems.
This type of conversation never happens with piano players.. or a secretary typing 80 WPM or any brass players that uses valves in playing. It happens with bass players because the results are negligible in sound, in other word the immediate cause and effect do not tie up..we cannot hear how many fingers are being used.
In the long term there may be a price to pay...maybe.
A balanced healthy use uses both sides of the hand, that is the radial side, which is the thumb, fore and middle finger, and the ulnar side, which is little and ring finger, with some middle finger ability. This also brings in daily hand use, how much have you used your hands before you even get to pick up that bass?
Anyone looking for speed in there playing is developing the wrong skill sets. Speed as i have said comes from better playing and time spent getting to know your instrument. It takes time to become proficient, that means a lot of things and includes playing fast.
