(I talk at the end)

This is the famous Carlos Gardel tango song El Dia Que Me Quieras ( the day when you'll love me )
I play guitar on MIDI keyboard. I wish i could play guitar like that huhuhu ;o )

This is an improv concept that will be featured in Volume Two of The Complete Guide To Improvisation which will be coming out soon. I was working on this concept with a private guitar student this week at Berklee. Here is the concept applied over Autumn leaves. The concept involves superimposing a Maj 7th #5 structure over any chord and outlining the Maj 7 #5 chord in the improv. We can also use the related Symmetrical Augmented scale as well as use passing and approach notes to notes in the Maj 7 #5 structure.
