Intervals
An Interval is the distance between two notes.
Intervals have two parts to their name: The Number and the quality, for example: A major 3rd. The name here tells us that is is 3 notes away from the Root Note and the sound is major. A minor 6th would tell you that the note is 6 away from the Root and has a minor sound.
First up - Locating your Root notes and find them across Octaves to start linking different areas of the fretboard.
THE BIG ONE! Aside from understanding the Root Note. Thirds control the quality of chords and scales. In music this is essential gender. Spent a good deal of time here as thirds are the building blocks of all music.
Most guitarist can already play a Perfect 5th interval but identify it as a Powerchord. Really is isn't a chord at all but an Interval.
5ths are perfect but can be sharpened and flattened as well.
7ths.
From here in we start to see to different qualities in our interval - a major and minor version. For 2nds, the major is much more commonly found in riffs and melodies.
Fourths are a departure from the thinking so far. They are not major or minor, instead referred to as Perfect. We can also sharpen a 4th
A great sounding but possibly underused interval. Popular in Blues and Funk genres.
