Bass Lesson # 11 (bass theory – sixth chords)

Theoretically, even for the sixth chords we can consider 12 families, since the 6 triads will be combined with the 6 M and 6 m intervals.

|
o | 6 (M, m)
|
o | |
| 5 (+, G, -)|
o | | |
| 3 (M, m) | |
o | | |

In the harmonic practice, however, we will go on to consider only 2 sixth chords, this because some chords that have an interval of 6 m are reduced to triads of 5+.
The other 4 chords of 6 m are strongly dissonant (contrast with the 5 or diminished).
Among the chords with the 6 M are rarely used those who have the b5, while those who have the #5 strongly contrast with the 6 M.
Therefore only the 2 chords of 6 M remain that combine with the 2 major and minor unaltered triads.
1) F – 3M – 5G – 6M = (chord) 6
2) F – 3m – 5G – 6M = (chord) m6
The 6th chord can be used as a substitute for the triad, which in turn can be replaced by the 7M.
C = C6 = C7M
Same thing with the minor triad.
Cm = Cm6 = Cm maj7
In the next lesson we will play on the bass the arpeggios of the 2 sixth chords.
