You're right, Mike. The ability to walk a bassline with your left hand and tastefully place right hand chords and fills in the "sweet" spot is beautiful thing! Then, for balads, the ability to do inversions and
hold full chords with the left hand and play complementary inversions and lead lines is a classic style I really enjoy.
We have a jazz arts society here, with many active members...many GREAT players. A while back, we had drummers, horn players and others show up for a performance...no bass players.
Everything at these performances is "on the fly" Counting all the solos, we played some tunes for 15 minutes or more.
GREAT FUN!
