In the video tutorial approach and surrounding notes – https://youtu.be/atrxDFfOEng
I describe approach and surrounding notes on a Gm7 chord as a part of the II-V-I in F major.
The Gm7 I mention in my video is the second degree of the scale – because of the function in the progression where I use it – the II-V-I.
This means that the Gm7 is taken out of F major.
Commonly, when the minor chord has a tonic function in music, the minor chord is the VI degree of the major scale – Gm7 would then be in the scale of Bb and indeed with a Eb.
You can check this video on the II-V-I to get more knowledge of the II-V-I.
The key is not F major, but I am sure this will help you.
Analyze and recognize the II-V-I – know your theory and apply it + two basic II-V-I licks
Let me know if my answer, answers your question.
All the best, play music and have fun.
