Major Chords Vs Minor Chords

minor chords vs major chords

Chords provide the emotional underpinning for any song and define its atmosphere and texture. As an amateur or experienced musician, understanding major vs minor chords is a fundamental aspect of music theory that should not be underestimated.

General speaking, a major chord contains the first, third and fifth notes from its scale while minor chords use similar intervals but lower its third note by one semitone (or half step). This difference represents its primary function.

Root Note

Root note in music theory refers to the lowest note in any given chord and serves to define its identity and tonal quality. For instance, chords composed of both major and minor thirds will typically be named after their roots; such as C, E and G (C Major), while chords that only contain major thirds are known as major chords.

Note that in major and minor chords, the root does not always correspond to the tonic; chords can be constructed in various ways: for instance a C major chord could be played using either its open 4th string as its root note, its 3rd fret of 2nd string as its tonic note, or even 5th fret of first string as its root note.

Understanding the difference between major and minor chords can help you create more compelling songs. They form the basis of many chord progressions and can create tension and release in your songs.

Major Third

As their name implies, major chords are composed of intervals from a major scale and tend to evoke positive emotions among listeners.

Major chords can be identified by their major third – an interval spanning two whole steps or half steps between two notes that serves as an earmark and can help identify them by sight or sound. This characteristic can help musicians recognize a major chord from its shapes or sounds alone.

To test this theory out, play both the C triad – composed of C, E and G notes – and D triad (D, F and A notes) simultaneously and listen for any differences; you will hear that while their first note remains unchanged between them, their second notes shift up one step in major chords versus one step down when switching between major and minor chords.

Major and minor chords have their own distinctive features that differentiate them, yet this distinction doesn’t always hold across cultures; indeed, in some musical cultures such as Japanese music there may not even exist the concept of major and minor.

Minor Third

Minor intervals consist of one less half step than major ones; thus C to E is considered a major third (4 half steps), while C to Eb would be classified as a minor third (3 half steps). Thus the term minor is employed rather than perfect or major when discussing these intervals (firsts, seconds, thirds, sixths and sevenths all have minor qualities).

Major intervals encompass four semitones or two whole tones and are the longest musical intervals, often found within major chords which tend to have an upbeat and joyful tone.

Western musical scales generally use major seconds as the initial interval that connects the first and third notes of a major scale; this interval can also be found in popular tunes like “Happy Birthday” and “Doe a Deer”. When measured using 24-TET and 5-limit just intonation systems, this major second has frequencies in proportions of 9:8.

Perfect Fifth

Perfect fifths in diatonic scales represent seven semitone intervals; for instance, C and G form an example of this interval. To check if any particular fifth is perfect or not, start from any note and count up towards G; if two notes are five apart they constitute a perfect fifth; similarly for D to E etc.

Knowledge of perfect fifth chords is invaluable, since many chords incorporate one. For instance, Twinkle Twinkle Little Star’s first chord consists of a C major triad containing an exact fifth.

However, when using chord symbols such as Cm7+ a perfect fifth would not suffice as that chord requires an augmented fifth which cannot be fulfilled by the perfect fifth alone! Therefore it is extremely important to familiarise yourself with the circle of fifths to gain better insight.
