Hey Guys, So I'm just curious to see how you approach this topic. A great interest of mine recently has been in developing the ability to play whatever lines or melodies or chord changes in all twelve keys. While the bass is a great instrument for utilising patterns, I feel that in order to really know a jazz melody or the like you should understand its construction and relation to the chords very intimately (this coupled with good technique would allow you to "break free" of playing the melody in fixed shapes every time). Now, the task at hand: How to do this effectively? One could learn the melody by scale degrees, however given the commonly shifting key centres of jazz this poses certain issues. One could also learn the actual note names, however over twelve keys it seems like there might be a better way. Opinions?
