Technically, any interval can be augmented by expanding it by a half-step. For instance, the augmented fourth is a perfect fourth plus a half step, etc.
However, an augmented 3rd would be incredibly unusual; a composer would be much more likely to write it as a perfect fourth.
Something "augmented" in music means that it is raised.

To learn music theory, there are step by step instructions in many music books. Alternatively a good music teacher should be able to explain music theory.
Generally, augmentation means to enlarge. In music theory, augmentation can be applied both to note values (time/duration) and to intervals (pitch relationship between to pitches). When you augment a note value you increase the duration of the note (the time you hold the note) over its previous value. Augmenting an interval is the process of increasing an interval by exactly one chromatic semitone (raise the interval a 1/2 step). In chord theory, an Augmented chord always means you are raising the 5th by a 1/2 step. Technically, you can augment any interval (unisons, seconds, thirds, etc.), but in practical terms, augmented intervals are reserved for the perfect intervals of 4ths and 5ths.
A third step in music refers to the interval between two notes where one note is two scale degrees away from the other. For example, in a C major scale, the interval from C to E is a major third, while the interval from C to E♭ is a minor third. This interval is foundational in creating chords and harmonies, as it defines the quality of triads, such as major and minor chords. The third is crucial in music theory for understanding scales, chord progressions, and harmony.
An augmented 7th chord in music theory is constructed by combining a root note, a major third, an augmented fifth, and a minor seventh. This chord has a unique sound that is both tense and dissonant, making it a versatile and expressive choice in music composition.
An augmented seventh chord in music theory is a four-note chord consisting of a root note, a major third, an augmented fifth, and a minor seventh. It has a tense and dissonant sound due to the augmented fifth. In functional harmony, the augmented seventh chord is often used as a dominant chord, creating tension that resolves to a tonic chord.
An augmented 7 chord in music theory is made up of a root note, a major third, an augmented fifth, and a minor seventh. It has a unique and dissonant sound that can create tension in music. This chord is often used in jazz and other genres to add color and complexity to a musical piece.
A plus chord, also known as an augmented chord, is a chord made up of a root note, a major third, and an augmented fifth. It is used in music theory to create tension and dissonance, often leading to a sense of instability that can be resolved by moving to a more stable chord.
An augmented chord is unique in music theory because it contains a raised fifth, creating a dissonant and tense sound that sets it apart from other types of chords.
In music theory, triads are three-note chords consisting of a root note, a third above the root, and a fifth above the root. They are identified by their specific intervals and can be major, minor, augmented, or diminished based on the quality of their third and fifth intervals.
The fundamental principles of triads in music theory are that they are made up of three notes - the root, the third, and the fifth - stacked on top of each other. Triads can be major, minor, diminished, or augmented depending on the intervals between these notes. They form the basis of harmony in Western music.
A Lydian triad in music theory consists of three notes: the root, the major third, and the augmented fifth. This creates a bright and dreamy sound due to the augmented fifth, which gives it a unique and distinct quality. The function of a Lydian triad is to add color and tension to a musical piece, often used to create a sense of mystery or anticipation in a composition.
An augmented third inverts to a diminished sixth.
A major minor diminished augmented chart in music theory is a visual representation of the different types of chords based on their intervals. It typically shows the root note of the chord and the intervals that make up the chord, such as major, minor, diminished, or augmented. This chart helps musicians understand and identify different chord qualities in music.
The augmented 3rd interval in music theory is significant because it creates tension and dissonance, adding color and interest to compositions. It is often used to create a sense of drama or to evoke strong emotions in music. Composers use the augmented 3rd interval to add complexity and depth to their pieces, enhancing the overall musical experience for the listener.
Intervals that are considered dissonant in music theory are the minor second, major second, tritone, minor seventh, major seventh, and augmented fourth.
