Intervals are the distance between two notes. Intervals played separately are called Melodic Intervals. Intervals played together are called Harmonic Intervals. The name of the interval comes from the distance between the lowest note and the highest note. Example, C to A is a major 6th.
There are two categories of intervals, Diatonic and Chromatic. Diatonic intervals are notes that appear naturally in the major scale. Chromatic intervals are notes that are not in the major scale. Chromatic intervals also require accidentals like sharps and flats.
