A seventh chord is a chord consisting of a triad plus a note forming an interval of a seventh above the chord's root. When not otherwise specified, a "seventh chord" usually means a dominant seventh chord: a major triad together with a minor seventh.
In music, the seventh factor of a chord is the note or pitch seven scale degrees above the root or tonal center. When the seventh is the bass note, or lowest note, of the expressed chord, the chord is in third inversion Play (help·info).
The reason behind its name "dominant seventh chord" is because, in a C7 chord, the B flat is the 7th note of the C dominant scale (also known as the Mixolydian scale). This contrast with the regular major 7th found on a Cmaj7 (which is the note B natural).
Dominant 7 chords are very similar to major 7 chords and only differ by one note. To turn a major 7 chord into a dominant 7 chord, you just need to lower the added note by a half step. So you'll have a root, 3rd, 5th, and a flat 7.
Dominant chords—particularly dominant seventh chords—provide a sense of tension, which helps keep music engaging. Their inherent tension comes from a note interval known as a tritone. A tritone is an interval of three whole steps—for instance going up from C to F♯, or from A to D♯.
The 7th of any chord resolves DOWN by step. The root of a Neapolitan chord (lowered 2nd scale degree) resolves DOWN by diminished 3rd to the leading tone of a V chord.
There are five qualities of seventh chords that appear in diatonic music: major seventh, dominant seventh, minor seventh, diminished seventh (also called fully-diminished), and half-diminished seventh.
The 7th is the seventh note of the major scale. To flat a note means to lower it by one note (meaning one fret lower). Therefore a flat 7th means one note lower than the 7th.
In your harmonizations of melodies, it is best to use seventh chords to add tension as you approach tonic function. Therefore, sevenths are added most frequently to chords of dominant function ( V and vii ) and chords of pre–dominant function ( ii and, to a lesser extent, IV ).
The seventh chord is B – D – F – A, a diminished triad and a minor seventh. Therefore, it is a half-diminished seventh chord. The eighth chord is a repetition of the first (C – E – G – B), making it a major seventh chord.

The A melodic minor chord i7 is the A min-maj 7 chord, and contains the notes A, C, E, and G#. This tonic 7th chords root / starting note is the 1st note (or scale degree) of the A melodic minor scale. The roman numeral for number 1 is 'i', and is used to indicate this is the 1st chord in the scale.
Harmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz (2 x 50Hz), a 3rd harmonic would be 150Hz (3 x 50Hz), a 5th at 250Hz, a 7th at 350Hz and so on.
How Do You Find The 7th Note of a Chord? In music theory, the way to find this 7th note of a chord is to count up to that 7th note in whatever major scale the chord is in. Then you need to lower that note. For example, F# becomes F or B becomes Bb.
It is created by taking a minor triad and adding a note a minor seventh (10 semitones) above the root. e.g. a minor seventh chord on C contains the notes C-Eb-G-Bb (Bb is a minor seventh/10 semitones above C).
A dominant seventh chord consists of the dominant triad (fifth note of the scale is the root of the dominant chord) and an added note a minor seventh above the root. For example, the dominant seventh chord in C major (or minor) is G-B-D-F.
A dominant 7th chord is built by taking the major triad and adding a 4th note which is a minor 7th interval about the root note. In C, this would be C, E, G and Bb. A dominant 7th chord symbol or the way of writing it in shorthand is to just have the tonic note of the chord followed by a 7.
Firstly, using dominant 7th chords sounds a lot better and much bluesier than using straight major chords. Secondly, when you use these 2 shapes, you can play the whole 12 bar blues progression very neatly in a box shape, using only a small portion of your neck.
Dominant seventh chords are often built on the fifth scale degree (or dominant) of a key. For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G7 (shown above). In this chord, F is a minor seventh above G.
Dominant seventh chords are a big contributing factor to the overall sound of blues music. While blues music doesn't always use dominant seventh chords, it is still very common to see these chords throughout blues songs. A dominant seventh chord is made by adding a lowered seventh scale degree to a major chord.
