What is the difference between a minor 7th and a diminished 7th?

The half diminished chord (m7b5) has a minor seventh (7) - it's a m7 chord wth a flat five (b5). The diminished chord has a diminished seventh (dim7, °7). The minor 7th is again decreased by a semitone and hence is equivalent to a sixth (6) - only the theoretical approach is different.

What is the difference between a half diminished 7th chord and a fully diminished 7th chord?

The fully diminished seventh can be indicated as dim7 or with the ° symbol. A half-diminished seventh chord is a diminished triad with a minor seventh added to the chord and can be indicated with the ø symbol. A diminished major seventh chord is a diminished triad with a major seventh, often indicated with °M.

What is Shell voicing?

A chord voicing that contains the root, third, and seventh of the chord, with no fifth. ... Since the third and the seventh define the quality of the chord (major seventh, minor seventh, etc.), and the root is generally covered by the bass, just those two notes are enough to outline the harmony.

What makes a diminished 7th chord?

A diminished seventh chord is a diminished triad, with an added note of a diminished seventh interval from the root. A diminished seventh chord contrasts from the half-diminished seventh chord in its seventh note; the half-diminished seventh is a diminished triad with a note added that is a minor seventh from the root.
