Chris, I really appreciate your doing these videos because they are very helpful for us intermediate jazz bassists. When you get ready to do the next one, I hope you'll consider two topics I struggle with: 1) transitioning into and out of thumb position
Thanks, Tom. When I do the first thumb position video, it'll probably be much like the master class you attended, since that's the material I find most useful to pass on that tends to really get people rolling. As far as transitioning to TP, there are three basic things that I do:
1) when actually transitioning via line or arpeggio, I'll almost always get up into the TP area without using the thumb and then place it down
behind a fingered note that has already played. This allows me to find keep my intonation without losing the left hand connection to the fingerboard. Once a higher finger is playing, it's pretty easy to gauge the distance to where the thumb should be.
2) For ascending linear passages where the line goes way up high in TP, I'll sometimes cross the thumb into the line in place of another finger, but I much prefer the method mentioned above. In general, when practicing 2 octave scales, I don't use the thumb at all even when technically crossing into and out of TP - instead focusing on two-note/two-finger groupings in the LH. But if the line goes so high that this starts to feel awkward, I'll cross the thumb in.
3) For cold leaps up into TB, I do the same things most other players do - using physical landmarks on the bass, using a slight, almost imperceptible LH scoop or gliss into the note to try to center it. I don't know if you noticed, but every single faculty member at the workshops has their own personal way of finding this range. I've been watching this for years, and it still fascinates me.
and 2) hammer-on pull-offs. the 2nd, I haven't seen that much material about. It'll probably be a while before I see my teacher next - he's a very busy guy - so I'd love to hear your insights on this.
I'll definitely do a hammer on/pull off/ghost note video at some point, but I think I'll have to backtrack and do a couple of walking bass topics next since that's such a big part of what we as bassists do when playing jazz, and since I want the series to kind of build from the ground up; the only reason I haven't done so so far is that there are so many walking bass methods and vids out there already. Having said that, I'll mention a few things about hammers and pulls:
Hammer on: just as the name suggests, hammer-on technique is just like the name describes - using force and velocity to to press down an ascending note from an existing sounding note without necessarily re-striking the string with the right hand. As such, it sounds like a separate technique, but in point of fact I actually try to do this to some extent with the left hand whenever I play any ascending interval on the same string whether I'm re-striking the string or not as I think doing so produces consistently better stops. If you read back a page or so into the thread, you'll see some criticism of my left hand technique which from a certain pedagogical perspective has some validity; specifically, that in the lyrical examples in the video I had too much distance between my outer fingers of the left hand and the fingerboard (I call this "free/vibrato position" in the video). The reason I like to play this way at slower tempos is that it allows for left hand hammer velocity in ascending passages.
As an example, try this exercise: play an ascending octave G scale from the open G in 8th notes along the G string up to the octave. Phrase/finger the scale in note groups starting on the strong beats so that the scale finger 0-1, 1-2, 2-4, (insert your favorite fingering for the last two). Strike each note with the right hand as you ascend. Next, try the same thing striking only the first note in each group and letting the left hand articulate the second note. Unless your string height/setup is very low, you'll notice a marked drop off in volume on the second note of each group. Now with the first two groups only, raise the hammering finger farther away from the board so that it travels more distance before striking the second note and try to drop your elbow/arm weight into the finger dropping onto the string. When you do this, you should hear more volume on the second note. Then shift without lifting your arm weight off the board and do the same thing on the next pairing. Practicing scales like this - in 2 note groups with a hammer on the second note - is a great addition to traditional scale practice and helps develop good strong hammer technique that comes from the body rather than from the hand or arm. It's not a replacement for traditional technique or hand shape/placement, but can be extremely effective in certain circumstances, and can also help develop a fluidity of line since often it is the right hand that limits tempo rather than the left.
I'm out of time but will try to address the concept of pull offs later.
