Most typically, minor seventh chord refers to where the "seventh" note is a minor seventh above the root (a fifth above the third note). This is more precisely known as a minor/minor seventh chord, and it can be represented as either as m7 or −7, or in integer notation, {0, 3, 7, 10}.
Similarly, you may ask, what are seventh chords on guitar?
A seventh chord is a triad with an added seventh interval from the root. That seventh interval can be either major, minor or diminished, and is typically what makes the chord sound bluesy.
How is a Minor 7 Flat 5 chord formed?
In music theory, the half-diminished seventh chord—also known as a half-diminished chord or a minor seventh flat five (m7♭5)—is formed by a root note, a minor third, a diminished fifth, and a flat seventh. Its consecutive intervals are minor third, minor third, major third.
What is the difference between a 7th and major 7th chord?
When you see "maj7" in a chord, it means the seventh is taken from the major scale, and you'll use the formula 1-3-5-7. A Cmaj7 chord is the notes C-E-G-B. When you just see "7", the chord is a "dominant 7th" chord (I'll expand on this below). Dominant 7ths have the formula 1-3-5-b7, so C7 is C-E-G-Bb.
