Im sure you all have been practising Marchs chord substitutions and can all freely interchange major chords with major 7ths and major 6ths in any key.
Well now for April we will go into a little Minor work. When moving from a Major to a Dominant 7th , try slipping a Minor in between. Heres some examples:
F C minor to D7th (This reads as Major to minor to Dominant 7th )
C G minor to A 7th
G D minor to E7th
A E minor to F sharp 7th
D A minor to B 7th.
The above chord progressions from a Major thru a Minor to a Dominant 7th is a common musical progression....Try it out and listen to the changes as you pass from chord to chord. Aloha Brudda Al
