Hi guys, Im gettin ready for my music theory final and i missed this one days lesson and need a quick question. I am analyzing a seventh chord and need to know what all the intervals equal. For example i know that minor, minor,minor would make a diminished chord. Could anyone give me all the combinations? Id really appreciate it
well ill give you a few, there are a lot and i dont really feel like going through all:
MmM: major seventh = _maj7
Mmm: dominant seventh = _7
mMm: minor seventh = _m7
mMM: minor major seventh = _mM7
MMM: augmented major seventh = _aug7
mmM: half diminished
mmm: full diminished

i think thats right and those would be the most common ones.

MMM would just give you an Augmented triad.
you saved my life man, thank you so much

no, MM would give you an augmented triad. I dont like this way of writing it out.

Root + Maj3 + P5 + Maj7 = Maj7 chord
R + M3 + P5 + min7 = 7 chord (said "dominant 7")
R + m3 + P5 + m7 = m7 chord
R + m3 + d5 + m7 = half diminished 7
R + m3 + d5 + d7 = diminished 7
R + m3 + P5 + M7 = Minor major 7

thats how Id teach them, although nothing previously posted was wrong.

it's a UtBDan sandwich. Awwww yeah!
^ yeah, thats how i usually look at them as well, but the threadstarter asked for the intervals between the notes. interesting way to look at it, but i prefer what you have as well.

He is right.. a major third from an augmented fifth would be a repeat of the tonic.

C + M = E
E + M = G#
G# + M = B# (C)

So MMM would be an augmented triad.

I think jof meant a maj7#5 chord, which would be MMm.

C + M = E
E + M = G#
G# + m = B.

C - E - G# - B is Cmaj7+.
