There are all kinds of books, videos, etc. out there but most end up saying the same thing. There are scales, chords and rhythm. There are all kinds of scales. All kind of chords and all kinds of rhythms, however all of them follow a few set patterns.
Don't try to learn it all at first. Take it one step at a time. The following may help with chords. My old standby chart of generic bass lines using the major scale box as a Rosetta stone may also help.
Major Scale Box.
........Index middle...ring....little
G~~|---2---|-------|---3---|---4---| 1st string
D~~|---6---|-------|---7---|---8---|
A~~|---3---|---4---|-------|---5---|

You may recognize this pattern with dots.
Adding the numbers lets the pattern come alive.
Cmaj7 chord coming up in the song. Find a C note on the 3rd or 4th string and put this box's R over that C note. Then play the "spelling" for the Cmaj7 chord. That spelling is listed below and it is R-3-5-7. If you wanted to play the C major scale, that spelling is 1-2-3-4-5-6-7.
Basic Chord Spellings
- Major Triad = R-3-5 for the C chord. A two note chord is usually a R-5 and called a power chord by us good ole boys.
- Minor Triad = R-b3-5 for the Cm chord.
- Diminished Chord = R-b3-b5 for the Cdim chord.
7th Chord Spellings
- Maj7 = R-3-5-7 for the Cmaj7 chord.
- Minor 7 = R-b3-5-b7 for the Cm7 chord.
- Dominant 7 = R-3-5-b7 for the C7 chord.
- ½ diminished = R-b3-b5-b7 for the Cm7b5 chord.
- Full diminished = R-b3-b5-bb7 for the C with the little o - no strike through.
See a chord and play it's chord tones. As every key will have three major, three minor and one diminished chord it's a good idea to get your major, minor and diminished bass line chord tones into muscle memory so when you see a chord your fingers just know what will work. Now the song may only give you enough room for the root, or root five - adapt and get as many chord tones into your bass line as needed. Root on 1 and a steady groove from the other chord tones plus something to call attention to the chord change is what we do.
Generic Notes - for your bass line.
- The root, five and eight are generic (R-5-8-5) and fit most any chord. Remember the diminished has a flatted 5.
- The 3 is generic to all major chords. So R-3-5-3 will fit under any major chord.
- The b3 is generic to all minor chords. And R-b3-5-8 will fit under any minor chord. Why the 8? Well the 8 is just another root in the next octave.
- The 7 is generic to all maj7 chords. Yep, R-3-5-7 fits nicely.
- The b7 is generic to all dominant seventh and minor seventh chords. G7 = R-3-5-b7 or Gm7 = R-b3-5-b7.
- The 6 is neutral and adds color, help yourself to 6’s. Love the sound of R-3-5-6 with a major chord.
- The 2 and 4 make good passing notes. Don’t linger on them or stop on them, keep them passing. Why? About the only chords that have a 2 or 4 in their makeup are the Sus and Add chords. So unless you are playing a Sus or Add chord forget about 2's and 4's for now.
- In making your bass line help yourself to those notes, just use them correctly.
- Roots, fives, eights and the correct 3 & 7 will play a lot of bass.
OK fine, how to use all that I know is the question. Get some fake chord sheet music. Google can find most anything you want using these search words --
chords, name of the song.
