Please explain to me how to it please thank you
What do you need explained?
how to play it or when?
I still maintain that you can play it when playing preacher chords, in this case, in the key of A major.
notice that in both the runs you gave, the pattern is the same:
--In the first set, you run the Ab add 9 chord,
then the AbM9, then the Ab9, then the Ab add 6/9.
--The second set is the same pattern, in Db. This makes sense because Ab is the 5th of Db & the 1 & 5 have a similar feel..
note how you are merely going a half step down with the 1st note in the RH while all else remains the same.
Another way of looking @ it is that you are descending by the 3rd of the 1st note on the LH with you RH or by a b7th of the 2nd LH note in set 1.
or descending by playing a 6th of the 1st note in LH or the 4th note of the 2nd note in LH.
I don't know what question really was.
