Topic: Jazz



Expert: Phil Kelly
Date: 11/8/2006
Subject: 6 vs. 13

Question
Why is there a 13 in dom. 7 harmony and a 6 in major, minor harmony?  Or, to put it another way, why don't you call a Cmin6 a Cmin13?

Thanks!

Answer
Hi Harry:

Since traditional harmony is based both on scales (  in a C tonality, major  or minor C=1, D=2 E or Eb=3 etc ) and chords traditionally built by thirds,
( C E G B or Bb D etc ), the chordal extensions above the seventh  are considered the ninth (D) , eleventh ( F or F# ) and thirteenth (A).

in dominant and major extended chords the 11th is normally sharp..
additionally in Dominant chords, the seventh will be lowered as well ...
in minor extended chords, the third, seventh are lowered and the 11 is normally natural.

Since a 6th chord doesn't exceed the range of an octave in the thirds system, the step above the fifth is referred to as a sixths. ( A similar situation exists if the D is added to a C triad ..it is referred to as an "add2 chord" or C2

However, if an EXTENDED  chord is employed, that same A ( and the F or F# if used ) will be referred to as the 13th and 11th ..

Hope this helps!
