That before, we learning about '7 and +7  Chords'. Now we will moving to 'part 6-2'. If you want to search about 7 key chord, use this formula:

Search 7 chords in Mayor (n 7):
Intv = n – 2 – 1 ½  – 1 ½

Search 7 chords in Minor (n m7):
Intv = n – 1 ½  – 2  – 1 ½

Search 7 chords in Diminish (n dim7):
Intv = n – 1 ½  – 1 ½  – 2

Example:
find this chords: Cdim7, D7 and Em7 ?.
Natural of Cdim7 = Db – Eb – F – Gb – Ab – Bb – C – n
Natural of D7 = G – A – B – CD – E – F# - n
Natural of Em7 = G – A – B – CD – E – F# - n

Search 7 chords in Diminish (n dim7):
Intv = n – 1 ½  – 1 ½  – 2

Cdim7 = C – Eb – Gb – Bb

Search 7 chords in Mayor (n 7):
Intv = n – 2 – 1 ½  – 1 ½

D7 = D – F# - A – C

Search 7 chords in Minor (n m7):
Intv = n – 1 ½  – 2  – 1 ½

Em7 = E – G – B – D

And, for +7 Chords you can try, and use this formula:

Search +7 chords (all type of chord ex: m, Mayor or dim)
Intv = n – n’

This is will really easier, because we're just using 2 chords of notes in the same time on different octave.

Example:
find this chords: C+7, D+7 and E+7 ?.
Natural of C+7 = Db – Eb – F – Gb – Ab – Bb – C – n
Natural of D+7 = G – A – B – CD – E – F# - n
Natural of Em+7 = G – A – B – CD – E – F# - n

Search +7 chords (all type of chord ex: m, Mayor or dim)
Intv = n – n’

C+7 = C – C’
D+7 = D – D’
E+7 = E – E’

That is all, hope this is will be useful for you, and see you next time in new learning...
