Probably I understood your problem.
Well the first thing that you have to improve, is the independence on the left hand and the crossing (fingering on different strings) on the right hand.
You can try with these starting (but not easy) important exercise:
on your left hands you have to play, starting from the first fret (just the first four frets for each string)on the E string this sequence:
Note
F-F#-G-G# then A#-B-C-C# then D#-E-F-F# than G#-A-A#-B
Left Hand
1-2 -3-4 so 1 -2 - 3-4 etc .....
after you play the combination on G string switch back on the D A and E with this combination on the LH 1243. Here the same; after you finish to play the last combination on the E string switch to the A-D-G playing the next one: 1324 etc etc.
So the summary for the full exercise is:
The
1st combination move down starting from E string to the D and playing the first 4 frets for each string.
The
2nd combination move up starting from the G to the A string.
Exercise 1
1234 - 1243
1324 - 1342
1423 - 1432
Exercise 2
2134 - 2143
2314 - 2341
2413 - 2431
Exercise 3
3124 - 3142
3214 - 3241
3412 - 3421
Exercise 4
4123 - 4132
4213 - 4231
4312 - 4321
When you work with this on the LH on the RH you have to play one note with the first finger and the next with the 2nd.
It's pretty important that you always alternate the fingering and give to the all notes the same dynamic. It will make your crossing more accurate with less "strength use".
This exercise is more electric bass but it's fit good also on the double bass. I hope you'll find this helpful. If you need more just let me know.
