Ok, so I'm doing a special concert and we're doing Birdland - and Jaco's Weather Report version floated across my desk. Good stuff. What I can't figure out is this - how does Jaco play the head at the beginning of the tune? I know he's using harmonics of some sort, but I can't seem to duplicate it. I've tried tap harmonics, tried holding the octave harmonic with my thumb while plucking with my finger, tried holding the harmonic with my finger and plucking with my thumb, tried picking while hitting the harmonic with my palm... I can consistently get the first harmonic, but not with the same tone that Jaco was able to get (he was also getting both the fundamental and the harmonic), and I really can't get the second octave harmonic to work consistently at all. What am I missing here? I figured with all you bass heads around here, somebody must know this tune inside and out.
