In music, a minor seventh chord is a seventh chord composed of a root note, a minor third, a perfect fifth, and a minor seventh (1, ♭ 3, 5, ♭ 7). In other words, one could think of it as a minor triad with a minor seventh attached to it. [2] For example, the minor seventh chord built on A, commonly written as A− 7, has pitches A-C-E-G:
Besides the dominant seventh chords discussed above, other seventh chords—especially minor seventh chords and major seventh chords—are used in guitar music. Minor seventh chords have the following fingerings in standard tuning: Dm7: [XX0211] Em7: [020000] Am7: [X02010] Bm7: [X20202] F ♯ m7: [202220] or ([XX2222] Also an A/F ♯ Chord)

The most common chords are tertian, constructed using a sequence of major thirds (spanning 4 semitones) and/or minor thirds (3 semitones). Since there are 3 third intervals in a seventh chord (4 notes) and each can be major or minor, there are 7 possible permutations (the 8th one, consisted of four major thirds, results in a non-seventh augmented chord, since a major third equally divides the ...
Extended chords add further notes to seventh chords. Of the seven notes in the major scale, a seventh chord uses only four (the root, third, fifth, and seventh). The other three notes (the second, fourth, and sixth) can be added in any combination; however, just as with the triads and seventh chords, notes are most commonly stacked – a ...
Minor chords are noted with a dash after the number or a lowercase m; in the key of D, 1 is D major, and 4- or 4m would be G minor. Often in the NNS, songs in minor keys will be written in the 6- of the relative major key. So if the song was in G minor, the key would be listed as B ♭ major, and G minor chords would appear as 6-.
The hallmark that distinguishes major keys from minor is whether the third scale degree is major or minor. Major and minor keys are based on the corresponding scales, and the tonic triad of those keys consist of the corresponding chords; however, a major key can encompass minor chords based on other roots, and vice versa.
Another well-known example occurs between the first two notes of the introduction to the main theme music from Star Trek: The Original Series theme. [4] The most common occurrence of the minor seventh is built on the root of the prevailing key's dominant triad, producing the all-important dominant seventh chord.
