The dominant scales I'll be learning are the same as the major scales we have learned, but the 7th note of the major scale is flatted. For example:
C Major Scale = C D E F G A B C
C Dominant Scale = C D E F G A Bb C
The recommendation from Ross Walters is to practice the dominant scales in sequence to its companion major scale so that I can switch to which ever is needed. Here is the cheat sheet I made to help me accomplish that assignment. The little arrows remind me to blow (up arrow) and draw (down arrow) on certain notes. If a note has two names I included both as explained below..
Practicing Dominant scales in combination with their major mode scales.
Why do I represent flatted notes as sharps. Well, on the Chromatic harmonica there is a way to raise any note a half step in other words to "sharp" it. We just play the note normally, ether blowing or drawing as required while holding the slide in. So when I see an A# , my brain knows that I just need to play an A with the slide. If I represent it as a Bflat, then I have to add a step of translation to find the appropriate hole. Of course I need to know both representations, but while I am initially learning the scales I prefer to show the notes with the sharp symbol.
Ross suggested practicing these against a dominant chord. But, it was easy to find backing tracks that would work for practicing so I went that route and am having fun with improv in the dominant scale.
Here is one example with me playing the Dominant C Scale over a backing track
