Gb melodic minor can be used when soloing over dominant 7th. Emphasizing the 3rd and 7th gives a great hint about chord progression. That’s going to help showing where you play to other band members.
I’m going to practice those several melodic minor lines for a while with several tunes.
To help navigate to first note naturally, I can use some sort of chord snippet which is the term I invented. It’s a small chord shape that help you guide the exact location of the note. Many guitar players might do exploit the chord shapes as their final resort.
You instantly come to the exact position when soloing over the chord progression. Instant reaction must be needed so that figures help a lot for your brain.
I’m going to internalize those shapes and sounds by sticking to these lines during my daily practice. I don’t know when my brain catches these, but I’m going to go with it at least one week.
