floating thumb techniqe

i've been pondering this one for years. personally, the best way for myself and from watching other bass players is to either anchor the thumb on the string above the one you're playing (which automatically mutes any lower strings) or lay it across the unplayed lower strings, like floating.
also, when playing the B/E string very aggressively - to dig in really hard and still keep the (lowest) string from vibrating out of control and lose good tone, i anchor the heel of my palm right around where the body contour starts on a P-bass. i press with a lot of weight on that spot and pluck the string with a little bit more up-pull toward the ceiling than normal. thumb doesn't need to do anything. when it gets real loud, that really works (for me)
 
I got into this with my teacher a few weeks back. He prefers anchoring the thumb on the pickup and feels by moving your hand less you are more efficient and play with more fluidity.

My deal is that I am a natural lefty who has always played right handed and I have fractured most of the bones in both hands, my right thumb area twice. Having to stretch my hands using his technique gave me a minor case of carpal tunnel. My right hand just doesn't want to open that much.

By floating letting my thumb rest on the lower string as I play I am more comfortable and can avoid sounding messy when my clumsier right hand brushes the wrong string on a riff.
 
Thanks Man for the link that's AWESOME !



hey TB'ers

instead of making a new thread i figured this would be the best location for this post.

Recently watching the Dave Matthews Band show live on HULU & Stefan Lessard's playing seems to really be impressing me these days.

take note of his technique, he is not floating his thumb but he does a great job at keeping both wrists straight and shoulders are very relaxed. his tone is killer on all his basses (especially the ken smith)

**as usual carter sounds sick

i play a fender jazz bass and wear my bass high. i have long arms & fingers, like pino, and struggle with this technique sometimes.
 
I find it easier to move my finger from the knuckle, not all the joints in unison to pluck a note. When you relax your hand complete you find the "neutral" position for your finger. That's how I play. I move my fingers around the neutral position and it's them most effortless way to do it. I switch around my "anchor" from PU, E, A string, to free floating when doing fast string skipping to D when I need to do fast G string runs.

With strict floating thumb my hand has to flatten a lot. Which makes my fingers curve a lot and in constant tension. It just isn't relaxed. Also my bony thumb doesn't have enough fat touch each string properly at all locations. I will continue to practice it to see the usefulness in certain situations and for future x-stringers. For now, it just doesn't work for me. You'd probably understand if you saw my hands.
 
I just started playing bass Dec. 2009, and in the past day or two concluded that I was going to have to move my thumb at least over the A string if I were to have control over the damping. There is this temptation to put something under the A, D, and G strings by the nut and forgo using them as open strings, and use the thumb to damp only the E string.
 
Ok maybe someone had already replied the way that I'm about to but I don't have time to read all 12 pages of this thread.

Moveable anchor: Just as Adam Nitti described. The thumb is anchored to the string below the one that is being plucked. The plucking fingers tend to be fairly straight, at least for me. I don't know why Adam calls it a floating thumb but hey he knows a lot more about this instrument than I do.

Floating thumb: The thumb rests not on top of but ACROSS the string below the one that is being plucked. It's isn't anchored at all. Todd Johnson has a video of this on Youtube or you can find the link to it in the pro section of this forum. My fingers tend to be a bit more curled like a classical guitarist with this technique.

Either technique effectively mutes the string.

I'm starting to prefer the floating thumb method more, especially for intricate passages that involve skipping strings a lot. It feels a bit unnatural at first but and it's harder to use a heavy touch but because the wrist stays straight it's much more comfortable.

If I'm simply banging out a bassline on one or two strings, going from root to 5th or major 3rd or an octave up then I usually anchor my thumb.

I don't advocate either position because they both work well for me in certain situations.
 
I think the movable anchor and floating thumb are the same technique.

I am a former Adam Nitti student and he taught me the floating thumb technique but called it the movable anchor.

My thumb is never anchored anywhere but instead simply rests on the strings not being played. When moving across strings the thumb slides to the correct position to keep the strings not being played muted.

Hope this helps...
 
I learned on a 5-string and I've anchored my thumb to the neck pickup from the beginning. It's the only way I can play really. I just can't play right if my thumb isn't anchored, especially on the low strings. That's why I can't really play acoustic basses. One of the factors on whether I like a bass is if the pickups are of a shape that allows me to anchor my thumb on them.

That's how I started too. Practice, you'll get it. Now it feels unnatural to anchor my thumb on a pickup.
