Right then, this has been bumping around in my head for some time now, but I never bothered putting the time in to see if it would work.
One day, whilst reading about lefties who play reverse strung (G at top, down to an E) and the benefits that lefties could gain for their fretting hand if they used a right hander bass etc, I decided it might be worth trying out my right hand for fretting rather than my left (I am right handed, but i thought it might build strength, leading to a faster, stronger picking hand.) and so flipped my bass over 180 degrees.
My left hand was faster, but less controlled and focused (it really is all in the fingers
) with a flabby tone, it was however much happier to integrate the pinky finger (which has straightened out and gained 5mm on its co-part) both in the 1,2,3,4 and 4,3,2,1 styles, and seemed not too much slower than my right hand at picking (all my time practicing fingerstyle wasted
, my left lacks any co-ordination for moving up and down strings however). The sound was relatively consistent, and with a little practice, I may be able to even it out into steady notes.
The real thing was that my hand was completely relaxed and that felt wonderful! I now understand the tension is the enemy motto. I think this was mainly due to the lack of control I had over my picking with the left however, leading to longer, more languid strokes, and though that is bad, I think it shows my fretting hand's wrist has been strengthened in a different way to my picking hand.
My right hand was a different story; when it attempted the first songs I ever learnt to play ("Hey" by The Pixies and "Peaches" by The Stranglers) and failed miserably for a while, and after 15 minutes I could play a mockery of both songs, sliding with my index, and just about using the middle finger. Only a little worse than starting again.
Now, obviously the two hands develop strength in different muscles and parts of the hand, which overlap somewhat. This leads to different types of co-ordination and agility on each hand etc etc.
If your still reading this, I commend your patience
The question is: Should I set aside and hour or so of practice time (I can find myself about 4 if I really want) a day to make both hands more well rounded and strong in both ways, with the hope that it will improve my ability and stamina overall? (As well as provide a neat little stage trick
)
Or will this just confuse me/destroy my technique/damage my wrists/make my joints arthritic even sooner etc?
With the masses of experience on here, and the sheer number of different opinions and viewpoints available, I thought I may as well ask.
P.S
Sorry for all the pointing out the obvious things you all know already, for creating a wall of text, and using "picking hand constantly", (as well as brackets) and the long, oddly phrased sentences.
My writing really doesn't read like a UK native's should does it?
