All fourths are perfect in quality, containing five half steps between notes — except for the fourth from F natural to B natural, which contains six half steps (making it an augmented fourth). There is an A position and a B position in this chord type. The perfect melodic octave has 12 half steps between the notes. Naming intervals A descending major 3rd is made of 4 semi-tones Every descending major 3rd share a common sound. To make the same octave diminished, you decrease the distance between the notes by one half step. It stays a perfect fourth. In common practice music, it can be both consonant and dissonant: in this case, it has a need for resolution when unsupported by lower notes, in which case it is dissonant even though it sounds as "good" as the fifth.

If the natural fourth is perfect, adding the same accidental (either a sharp or a flat) to both notes doesn’t change the interval’s quality. E up to C: Minor 6th. Again, just as in a perfect fourth, if a fifth is perfect (every case except F natural and B natural), adding the same accidentals to both notes in the interval doesn’t change its quality. Minor sixth. Cheerfulness, stability. Unison means two notes with exactly the same frequencies. Unisons, octaves, fourths, and fifths share the same characteristics in that they all use the terms perfect, augmented, or diminished to identify their quality.
