Thanks for the advice. Just tried it and it works amazingly well. I combined it with playing the major scales up and down to narrow it down.

Patrick, just to add to the help @stitch has given,
Major, minor and diminished chords are the fundamentals. They are triads made up of three notes. On guitar, played as chords, many of those three notes have octave repeats somewhere in their chord form.
When you add in extra notes the first step along that path - which converts them from triads to what Justin calls quadads - has the effect of making them extended chords and they become either major 7 (maj7), minor 7 (m7), dominant 7 (just written as 7 mostly, this is another type or extended major chord) and diminished 7. But the latter does not usually go by that name - perhaps confusingly. It is often called minor 7 flat 5 (m7b5) or half diminished.
do we have to practice it for 1 week?
