The intervals in a major scale between the first note and the other notes are:
Types of interval
Intervals according to the distance between notes
Intervals according to their aural qualities
Every musical interval has a particular aural quality, and when that interval is present in a chord, it will contribute that quality to the overall sound of the chord itself.
Enharmonically Equivalent Intervals
In our tempered scale system it often happens that two or more intervals sound alike when played on the pianoforte, even though they are widely different in their meaning. A good example is the augmented second, which cannot be distinguished from the minor third without further evidence than the sound of the two tones. One interval is called the enharmonic equivalent of the other. When these intervals are heard in their harmonic context, however, their difference becomes clearly audible.
The most common enharmonic intervals are the augmented fourth and the diminished fifth, which divide the octave into two equal parts. These intervals are usually referred to as the tritone, since they contain three whole steps (three tones).
The two pitches of an interval occur in succession. If two tones are positioned adjacently and sound one after the other, the resulting interval is considered to be melodic.
The two pitches of an interval occur simultaneously. If two tones sound at the same time, the resulting interval is said to be harmonic.
Those intervals that span eight scale steps or fewer are called simple intervals.
Those intervals that span more than eight steps
