does anyone know like what these are respectively, and how they differ from normal major/minor chords/arpeggios?
#2
someone correct me if i'm wrong, but i'm pretty sure a diminished chord is a major chord with a flat 3rd and 5th, and an augmented chord is a major chord with a #5th. They are "ugly" sounding chords, but can sound great in the right context (just like anything I suppose). I'm not really sure how augmented chords fit in with major and minor scales, but in the minor scale, the ii chord is diminished. In the major scale the vii chord is diminished.

half diminished is the vii of the major scale. a fully diminished (bb7) is dissonant to all keys

edit: oh my bad forgot we were looking at triads

major = 1 3 5
minor = 1 b3 5
half diminished = 1 b3 b5 (b7)
diminished = 1 b3 b5 (bb7)
augmented = 1 3 #5

A Diminished chord is built on the vii degree of the major scale and has is spelt 1 b3 b5. It is mostly used in first inversion and acts as a dominant. If you add the diatonic 7th you get a minor 7th which leads to a half diminished ( or _m7b5) chord.

If you build a 7th chord on the vii degree of the harmonic minor scale you get a diminished 7th chord ( 1 b3 b5 bb7).

Augmented chords ( 1 3 #5) are built from the 3rd degree of the harmonic minor scale, used as passing chords in jazz and used in some 20th century music.

If you add a minor 7th to an augmented chord you get a _7aug or a _7#5 chord. These act as dominants in minor keys.

Its a seventh that has been flattened again. It is enharmonic (same pitch, but different note name) to a major sixth.

it's two b's and a 7

and i was here thinking it was a double diminished 7th.

Quick tip: A diminished 7th arpeggio goes up and down by minor thirds, and an augmented arpeggio goes up and down by major thirds.
