I found out that even when I play slow the middle finger does its circular movements. Here's what happens: the middle does a decent follow-through after the pluck, but as it returns, my first knuckle (the big one at my palm) lifts the finger much higher and further than it needs to to clear the string, and then kind of swoops down in this crazy arch to pluck the string.
I found out, just by messing around, that if I tuck my ring and index finger into my palm, the middle finger's oval movements are a little flatter and hence less movement. I was playing quarter notes at about 80 BPM (4/4 time) on the open G string while staring at my fingers to make sure to primarily use my second knuckle to move my middle finger and not relying on the big one, thus creating consistancy between the two fingers. I don't think I'll be playing anything musical for a while, LOL, it really seems like I have to completely re-write 5 years of right hand technique, until this feels more naturally anyway.
Another thing that seems to help is I adapted part of this exercise by TB'er 'Deacon_Blues' (the rest can be found in post #1 of the "Exercise Sticky" thread:
"...Start for instance on the G string. Rest your index finger on it and the middle finger on the string below (D). Then pluck the G string with your index and simultaneously move your middle finger to the G string to mute it. The result should be a staccato note as short as possible. Well, now your index is resting on your D string and your middle on the G string. Then pluck the G string again with your middle finger and move up the index to mute it as quickly as possible, i.e. exactly the same thing as you already did, only with switched fingers. Now you're back where you started..."
I personally did a slight variation of it though, because I like playing with free strokes as opposed to rest strokes, so I wouldn't rest my finger on the lower string, but the concept is the same.
I did this for eight quarter notes, and then play eight quarter notes legato and then go back to the staccato exercise, all on the same string. It will take me a while but it will certainly help. A good thing too is that I don't have to be playing bass to practice favouring the second knuckle, though I'm going to try to do it as much as possible for the mental association.
Thanks again everyone, and I hope this thread is helpful to anyone else out there. I'll update back in a couple of months or so.
Its just a tight tendon you have going on it is not a problem so do not make it one.....just now. Incorporate finger stretches to help loosen it off.
Plucking movement originates from the middle knuckle ( look at this as bottom, middle and top knuckle from the hand) not the bottom knuckle.
The Bottom knuckle move because the middle knuckle needed support for its movement.
Now as an exercise play slow and do not lift the fingers up from the strings, but rather curl the finger in to the palm and keep it there till it is needed again, so it is a free stroke, but an exagrerated one.
If you look at what you are doing you will notice the finger need to curl in and out to play the exercise.
When you play for real you will see the motions are related but the exercise is a controlled exaggeration of the movement.
As for those finger stretches try this
Spread your fingers long and straight, then fan them out, really stretch them apart and hold for 10 sec.
Pull them together, keeping them long and straight, then relax.
Wiggle the finger and repeat as many times as you need to.
Spread your fingers long and straight, then fan them out, really stretch them apart and hold for 10 sec.
Pull them together, keeping them long and straight, then fan them out again and bring them back straight. repeat this about 20 times, them relax and give them a good wiggle.
These two stretches will exercise the fingers and hands and keep them healthy. Playing bass is about using the hands in semi closed to closed positions, these exercises help "remind" the hands of the other functions and movements it has. These exercises can be seen as helping relieve the stresses of playing rather than adding to them. A healthy hand has full movement and a healthy hand is a good hand for life.
