An interval is the distance from one note to another. Usually it is measured in steps. For example, a Major 2nd is 1 whole step apart and a minor 2nd is 1 half step apart. Different intervals create a melody. There are three main types of intervals, Major, minor, and perfect. Major Intervals Major intervals sound bright and are marked by a capital letter M. The Major intervals are a second, third, sixth, and seventh.
Minor Intervals Minor Intervals have a more dreary sound to them. The minor intervals are minor seconds, thirds, sixths and sevenths.
Perfect Intervals Perfect intervals either sound very much the same because they are the same note, or a little foreign. The perfect intervals are 1, 4ths, 5ths, and octaves.
