third position?
David is there a place in your series where you play a song first in second position and then in third? I have discussed the third positon with a long time player (since 60's) and he just recently played his first third position solo. We both questioned whether a song needs be be tailored for third position or will it work fine for any song. I have tried at times to incorporate just a few licks of third into second position playing and have not been thrilled with it (except for occasional horn type hits on the 1-4 octave).
Hey Bob.
Let me start by saying that to play "in" 2nd is to play in a key... C Harp in G... to play "in" 3rd Position is to play in a key... C Harp in D.
That said... are we playing in a "key," or are we playing within a "chord" when we're over that chord in the 12 bar blues?
The answer is yes to both. The tonal center of a song IS the key... C Harp in 2nd Position in the Key of G... G is the tonal center... ALL phrases/notes will have to resolve to G at some point.
When moving to the IV Chord, you're now playing over a structure of C... C E G Bb in most cases... so your movement is based on those notes. Though you are still IN the key of G, your focus in on C and the notes associated with the C Chord. This allows us to play a 1st Position lick over the IV Chord, as long as it gracefully weaves itself back to G when the I Chord comes back.
The same idea applies to the V Chord... you can use 3rd Position licks on the V Chord due to it being a D7 Chord... the same chord as the I Chord in 3rd Position (D7).
With this said, using licks from other positions should be reserved for chord change... not within the I Chord. There are some soloing concepts in the Jazz world that are interesting to explore in this matter, but do not have much traction for blues harmonica players.
