Kind of Confused

It's the same scale, as you say. Does it sound like Db major or Eb minor? Does it sound good? (the ultimate answer). Post the clip and transcription if you can.

 

Also, melodically any chord from the family of chords works over any chord in the set. For instance play on the piana the Ionian chord in your left hand and aprgeggiate all of the chords, one by one, of the family of chrods in your right hand and you'll see that it makes melodic sense.

 

what is he playing the implies Db/-\ ?

 

I think you might be blinded by the trees a bit. From that first line you put out I just see D dorian. The C# might be a little 'A7'ish sounding, but he's just playing melodic ideas with the D dorian sound being the dominating flavor.

 

Disagree. His phrases look two measures long in which case he started once on the 3rd, once on the root and the other on the 5th.

 

I would say not, just as each note in the scale has it's own quality.

The numbers (modes, etc.) give you some note choices, but that's all. Beyond that you have to use your ears, and by really knowing the sound of your choices you know what colors you have to create your line (solo or bass line). Also note that you have other things that you can use, like pentatonic scales and chromatic notes (neighboring tones) as in your example above.

 

P.C.'s note choicees on So What were discussed at great length in an older thread. This one? His lines over the bridge do seem to suggest Db Major, which is somewhat perplexing, but if you listen to everything else that's going on, including the melody, it's obviously Eb dorian.

When you are first learning to walk over one chord for many measures, it is important to place your roots in strategic locations. IOW, don't start off taking a bunch of liberties with any note that strikes your fancy, or where your hand happens to wander. At the very least, you should put a root on the downbeat of every section. Better yet, every four bars. Better still, every other bar, and alternate with the fifth as target note. By doing this, you will help yourself as well as the rest of the band by defining the form, and not getting lost.
