Intervals are used in all styles of guitar music from pop, blues, country to jazz and classical music.
Learning to play and understand intervals are a great value to your guitar playing. It will help you to understand chords, scales and add beautiful melodic and harmonic ideas to your improvisation.
Today I’ll start with the interval of a third. It’s probably the most often used interval in pop music, but also widely used in all other styles.
In music theory, an interval is the distance in pitch between any two notes. When you play these two notes simultaneously they are called harmonic intervals. When you play the notes separately one after the other they are called melodic intervals.
Here are two ways to determine intervals:
1 – Finding intervals by counting the number of semitones between the two notes.
2 – Finding intervals within a scale. (diatonic intervals)
