I am wondering what most of you are using as your default left hand position, in TP, when improvising.
I find that I habitually use the closed hand (m3rd) when soloing and open up to the extended hand (covering a P4th) less often. While I use the open hand for playing heads, hitting an easy 4th, reaching oddball notes, etc., I always seem to revert back to the closed hand, mostly.
I am working on undoing this habit, since it makes so little sense. I have been working on more stuff with the open hand, recently, switching back and forth between the open and closed fingerings. Better players than me, whom I was lucky enough to study with in the past, used both hand positions interchangeably.
We certainly use the open hand for "classical" stuff (with worked out fingerings, etc.). God knows you can reach a lot more notes, hence my motivation, but I haven't got it grooved into my musical mind/muscular memory yet, for improvising, really.
What are you good people using in TP; open hand, closed, or both? Please do flame me if this has been discussed ad nauseum (of for any other reason

); I couldn't find it in the archives.
