i really have problems with coming up with cool riffs and i would like to know from you all what i could do with theory ideas or scales.
I am going to assume that you already know about scales, chords, arpeggios, and tensions, etc based on your question. You should practice playing on one string. Don't even worrry about the fingering. Using one finger for this exercise is fine. Identify all the notes on the string for the scale you want to play in. Now try playing some melodies. Make anything up. You don't need to worry about remembering phrases, arpeggios, or anything. Just try to make it sound musical. Pay attention to phrasing and how the intervals sound. Don't forget to throw in some chromatic approaches, and out of key notes. Listen for how they affect the feeling. If you really want to get good at this, try to sound like a sax player. Try not to get hung up to much on phrasing within a measure while doing this. Bass players are often so accustomed to playing patterns that we forget how to play outside the box. Now ask yourself: Does your playing make you feel strong emotion? Does it make you want to laugh or cry? If not, how can you expect your audience to feel this way? Once you feel comfortable with one string, try another. Once you get 3 or 4 strings down try combining them. You almost never need more than 2 strings. This will do more for you playing than almost any other exercise.
Listen to some different styles of music that you haven't listened to for a while or have never listened to. Or, I read (or reread..) and old article in Bass Player mag. that one way to come up with a new line was to retune your bass , i.e.- tune each string up or down a step or two, then play a familiar pattern and see how it sounds. As strange as it sounds, I've tried this and actually came up with something.
c major. j/k. how and why would someone have a favorite scale? i just play the notes that sound good to me, then i go back and see if it was actually even in the same key and give that info to my guitarist.
d minor... its really just the saddist scale... (in case you didnt get it, go rent "This Is Spinal Tap" right away, and you'll soon get it.
My lame G# major joke has gone unnoticed. I don't understand how someone can have a "favorite" scale. Context people. Context.
Wait, wait, let me add that to the Idiot's Guide to Scales thread. Okay, let me think, modes of the whole-tone scale. Hmmmmmm........ Bite me Chris.
