The major seventh chord, sometimes also called a Delta chord, can be written as maj 7, M 7, Δ, ⑦, etc. The "7" does not have to be superscripted, but if it is, then any alterations, added tones, or omissions are usually also superscripted. For example, the major seventh chord built on C, commonly written as Cmaj 7, has pitches C–E–G–B:
The leading note and the subdominant note combined form a diminished fifth, also known as a tritone. The clashing sound produced by playing these two notes together gives the dominant seventh chord its dissonant quality (i.e. its harmonic instability). [4] Dominant seventh chords are often built on the fifth scale degree (or dominant) of a key.

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 seventh implies that there is a fifth and a third and a root.
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 ...
This allows for the note range of B standard tuning without transposing E standard guitar chords down two and a half steps down. Baritone 7-string guitars are available which features a longer scale-length allowing it to be tuned to a lower range. Standard 7-string tuning – B'-E-A-d-g-b-e' Standard tuning for a seven-string guitar.
Put another way, it is the key whose tonic is the dominant scale degree in the main key. [8] If, for example, a piece is written in the key of C major, then the tonic key is C major and the dominant key is G major since G is the dominant note in C major. [9] "Essentially, there are two harmonic directions: toward I and toward V.
V 7 ⓘ (dominant), ii 7 ⓘ (minor), vii ø 7 ⓘ (half-diminished), IVM 7 ⓘ (major), vi 7 ⓘ, IM 7 ⓘ, or iii 7 ⓘ When playing seventh chords, guitarists often play only a subset of notes from the chord. The fifth is often omitted. When a guitar is accompanied by a bass, the guitarist may omit the bass note from a chord.
