When two tones of different pitches are played in succession , it is called a Melodic Interval. When two tones are played together, it is called a Harmonic Interval.
Unison Interval – two notes of the same letter – two notes of the same pitch.
Perfect Interval – The Unison, fourth, fifth, and octave are called Perfect intervals because they remain constant from key to key.
Minor Intervals – Lowering the upper tone, one half – step or raising the lower tone a half-step. The second, third, sixth and seventh intervals may be played as Minor Intervals.
Diminished Intervals – The diminished interval is obtained by bringing a Perfect interval or a Minor interal one half-step closer.
Augmented Intervals – The interval between two tones is expanded. Raising the upper note one half-step, or lowering the lower tone one half-step.
Tritone Interval – The interval between the fourth and fifth.
Unison Interval – two notes of the same letter – two notes of the same pitch.
