The C major chord is the chord that you will learn when first learning music.
The Tritone
The harmonic series is which notes a brass player can play without using any valves. The notes are based on the major chord of the key the instrument is in. It's not all notes that are part of that chord. The lowest note is the key the instrument is in. The next is an octave up. The next is the top note of the chord, then the base note again, then the full chord is accesible. After that, the notes get closer and closer together.
Assuming you are referring to a chord symbol, like G9 for example, it usually refers to a dominant 7th chord with the ninth degree of the scale added as a color tone. For example, a G9 chord contains the notes G-B-D-F-A, the first, third, fifth, flatted seventh, and ninth notes of the G scale. (The flat 7th, F natural rather than F#, is what makes it a dominant 7th chord.) You also can build a ninth chord using the diatonic 7th step of the major scale, but that kind of chord is called a major 9th rather than a 9th. In G, the major 9th chord (often notated Gmaj9), would be spelled G-B-D-F#-A.

A minor sus4 chord adds tension and color to a harmonic progression by creating a sense of instability that resolves back to the original minor chord.
The dominant chord in a harmonic progression creates tension and leads to the resolution back to the tonic chord, providing a sense of closure and stability in music.
The minor V chord in a harmonic progression typically creates tension and leads back to the tonic chord, adding a sense of resolution and musical interest.
The leading-tone seventh chord functions as a dominant chord in a harmonic progression, creating tension that resolves to the tonic chord. Its resolution helps to establish a strong sense of finality and closure in the music.
The ii65 chord in a major key progression serves as a pre-dominant chord, creating tension and leading to the dominant chord. Its harmonic significance lies in its ability to establish a sense of movement and anticipation within the music.
The common voicings of the ii6 chord in music theory are the root position and the first inversion. The function of the ii6 chord is typically to create harmonic movement and lead to the V chord in a progression.
The v7/ii chord in a musical composition serves as a dominant chord that creates tension and leads to the ii chord. Its significance lies in adding harmonic interest and creating a sense of resolution when it resolves to the ii chord.
A minor second chord in music theory creates tension and dissonance, often leading to a sense of instability. It is typically used to create a sense of urgency or to add color and interest to a harmonic progression.
The harmonic function of a Phrygian cadence in music theory is to create a sense of resolution or conclusion. It typically involves a chord progression from the minor subdominant to the minor tonic, giving a distinctive and resolved sound.
The root of a chord is the note that gives the chord its name and serves as its foundation. It impacts the overall sound of the chord by providing a sense of stability and defining the key of the music. The root note helps determine the quality and character of the chord, influencing its emotional impact and harmonic function within a piece of music.
In a seventh chord, the essential tones that should not be omitted are the root, the third, and the seventh. The root establishes the chord's identity, the third defines its quality (major or minor), and the seventh adds depth and tension. Omitting any of these tones can weaken the chord's harmonic function, particularly in a dominant seventh chord, where the seventh is crucial for resolution. The fifth can often be omitted without significantly altering the chord's function.
The dominant chord in music theory is important because it creates tension and leads to resolution in a harmonic progression. It is based on the fifth note of the scale and typically resolves to the tonic chord. The key principles governing its use include its strong pull towards the tonic chord, its role in creating a sense of closure or resolution, and its ability to add excitement and energy to a musical piece.
