The Relationship Between Intervals and Chords

musical intervals and chord relationship

In music theory, an interval is the difference in pitch between two sounds. An interval may be .. When played as isolated chords on a piano keyboard, these intervals are indistinguishable to the ear, because they are all played with the same. The interval between adjacent notes on the chromatic scale is referred to as a half step. The number Chord progressions are the basis of most western music. All scales, chords, and most songs are based on intervals. we can say all music can be thought of as the harmonic relationships between the.

I could crawl into the space between the notes and curl my back to loneliness. Yet, despite the simplicity, the related theory can get fairly involved. In fact, much of it is outside the scope my own guitar playing. Therefore, I don't need to know it all.

Note that this is an abridged version of a larger lesson. What Is an Interval?

In music theory, an interval is the space between any two pitches according to Harmony: Its Theory and Practice by Ebenezer Prout. On guitar, it's simply space between any two notes on the fretboard. Take for example, the following tabbed interval: How does this work? Even on different strings there's still a linear line of frets separating any two notes.

We still count it the same way.

More on this later. What Are the Parts of an Interval? An interval on the guitar is only two parts: The Root Note 2. The Interval s Intervals are always understood in relation to some root note.

For instance, the open G in a C chord is not the interval of the note that falls on the second or first fret in the same chord. A Guitar Interval Chart There are a total of 11 different intervals before you get to your first octave, which doubles the frequency of the original note. So how do we read this chart and translate it to the fretboard? What do you do?

First, recall from our chart that a minor second is a one semitone interval. The root note is at the third fret G while the interval falls on the fourth fret. What About a Major Second? So C is zero semitones from itself, C is 1 semitone, D is 2 semitones, etc. The notes repeat from the first C to the next. The black keys can be described as sharps or flats b depending on what scale you are in.


The octaves are repeated in the graphic to display the black keys first as sharps and then as flats. The correct name of the note depends on what key you are in. Interval Number and Quality Above each interval can be described by its quality. So a P5 is a perfect fifth, and a capital M3 is a major third interval and lowercase m3 is a minor third interval.

There are only some of the ways to express which jump one is referring to. See Wikipedia on Interval number and quality. Any jump to a P will sound harmonic, any jump to a M will add flavor.

In a minor scale, the M3 becomes a m3 and the M7 becomes a m7. This can be transposed to any key by changing the root note by changing the note the scale starts on. In music, like other fields, sometimes two different concepts get the same name, a single concept will get a variety of names, or short hand expressions are used.

Music Theory — Understanding Intervals: The goal here is to introduce you to the logic behind music, once you get the logic there is a lifetime of things to learn. Intervals are the foundation of all western music harmonically speaking at least; I say this because rhythm, space in between notes, resonance, tempos, orchestration, and other such things are vital aspects of music. More on that below. Notice how the video below discusses shifting only between two chords.

Notice how each shift has a different harmonic quality? That shifting of intervals to create and resolve tension is what makes music harmonically. It is more obvious with chords than single notes anyway. This video will give you a sense of how musics can be thought of as a sort of math-based science. One can hear this with their ears, but one can also see this using the right equipment. Music is largely a thing of mathematics and physics in this sense.
