MAJOR THIRD Meaning and
Definition
-
A major third is a musical interval that spans two whole steps or four half steps. It is commonly denoted as M3. In terms of pitch, it is the distance between two notes that are three letter names apart. For example, the distance between C and E is a major third. The concept of major third is an important element in music theory and harmony.
In the context of a major scale, a major third occurs between the first and third degrees, as well as the fourth and sixth degrees. It creates a bright and consonant sound that is pleasing to the ear. Major thirds are frequently used in melodies, chord progressions, and harmonies to convey a sense of optimism, happiness, and stability.
In Western music, major thirds are widely employed in various genres and styles, from classical compositions to pop songs. They form the basis of major and dominant chords, blending with other intervals to construct harmonically rich soundscapes. In contrast to a minor third, which has a slightly different sound and mood, major thirds generally evoke a more uplifting and triumphant feel.
Understanding the characteristics and applications of major thirds is fundamental for musicians and composers. It allows them to craft melodic and harmonic choices that contribute to the emotional impact and overall aesthetic of a musical piece.
Etymology of MAJOR THIRD
The word "major" in "major third" comes from the Latin word "maior", meaning greater or larger. In music theory, major refers to a larger interval between two notes, while minor refers to a smaller interval.
The term "third" comes from the fact that it represents the interval of three diatonic scale degrees between two notes. In Western music, the diatonic scale is divided into seven degrees, and the third degree is considered an essential interval in harmonies.
Therefore, the term "major third" describes an interval that is larger (or greater) than a minor third, consisting of three whole steps or four half steps. This interval is essential in the formation of major chords and often associated with a bright and happy sound.
