When you go out to buy a book on scales you'll probably end up with a true
"thesaurus" in which literally dozens of different scales are given and
explained. Who has the time to work through such a book? My guess is: nobody.
In my (humble) opinion one only needs to know five different scales as
a help for improvising. On this page I want to discuss these scales and their uses.
You need to be familiar with terms like: altered, octotonic, mixolydian etc. If you're not
I recommend you first study our page on
Dominants and Subdominants.
You can use the C-minor melodic scale scale on the following chords:
- Cmin6/minMaj7
Very natural sound.
- Cmin7
Theoretically this is not "right", because the chord has a minor 7 in it and the scale
a major 7, but if you consider the major 7 in the scale as a
passing tone or a lead tone to C it sounds great! In fact: I use this scale
more often than the C-dorian scale (which is the same
as a Bb-ionian scale!)
- Amin7b5
Theoretically the best choice for this chord!
- F7
Mixolydian#11 sound. Very nice!
- B7
Altered sound. This is in fact the altered scale you're using now!
Now for the theoretical subject I was talking about. If you take all the chords
this scale fits too except for the Cmin7 you can make the following rule:
Cmin6/CminMaj7 = Amin7b5 = F7mixo#11 = B7alt. Yes! These
chords are all the same, only the bass-note, the root is different. This "rule" is
extremely handy when it comes to voicing the different chords: one voicing fits all.
