Intervals

There are different kinds of chords, depending on the intervals between each of the notes that compose it. To better understand chords, you should understand these intervals first. You can learn by playing different intervals on your instrument to hear them out and/or reading about them: : [1] [2]

In tablatures, chords will be identified by their root note (A-G) followed by the chord notation. If you see only the root note, you're looking at a major chord (or major triad).

This table shows how each chord is built. The intervals are displayed alongside the number of semitones from the root for each interval that makes up each chord.
