I mostly play chord tone bass lines. How do
you play a melodic bass line? I've never been melodic. Would like to see what I've been missing.
I understand there are a zillion ways we could go about this, I'm interested in
what you do when you want to go melodic. Where do you draw your notes from?
- The melody?
- The tonic scale?
- The tonic pentatonic?
- Each chord's pentatonic?
Thanks
When I play a walking bass line, I use two different types of patterns. One is basically arpeggiated chord tones and the other uses non chord tones. I think of the chord tones as creating a more vertical line because you typically stack notes that are interrelated by thirds, 1,3,5,7. When I use non chord tones I think of the process as more linear because you may travel from one scale degree to the next with out skipping any notes, 1,2,3,4,5,6,7,8
To play melodically you move in and out of both thought processes and also consider whether you want to create consonance or dissonance. Generally dissonance is quickly resolved to consonance, but if you don't throw some dissonance in, the melody may be a bit dull and lifeless.
Some other very importance concepts are the musical cadence and voice leading. These concepts relate to how chords resolve and how chord tones move within chords.
Ultimately I don't really thing about most of this stuff when I am playing an improvised melody. These are things you study so that you develop a musical vocabulary and foundation. With training and study, you hear a chord progression and rhythm, and different melodies just pop into your mind's ear. If you are sufficiently proficient on your instrument, you can play the melody on your instrument impromptu. When I am soloing, most of the time I short of shift in and out of playing impromptu by ear and using theoretical knowledge to keep my place.
When you study new chords structures and how they interrelate with other chords, it opens up your mind to new possibilities that you had not considered before.
So to begin, I suggest you start with the key center, the chord, and resultant modes. This should keep you busy for an fairly long time. At some point, if you stick with it, you can learn new rules, basically how and when to break the old rules you previously learned.
