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.

Besides, 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.

What makes up a minor 7th chord?

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}.

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 (m75)—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.
