At any given level, a harmony has varying degrees of consonance and dissonance. Dissonance is a annoying sound that feels a need to search out resolution. Consonance is the decision of the dissonance and subsequently the discharge of stress. Melody is probably the most troublesome of the characteristics to outline. While there is no good formal definition of “melody,” it’s loosely, the “music of the song,” or the “hummable” part of a bit.
Sometimes Rondo form may be a lot broader and be ABACABA or The first B section of a piece in rondo kind is usually within the dominant or relative main key. The second B part can path off to no matter key it needs to. It may also be viewed as an extension of both ternary kind or binary kind. The additional sections help outline it from other forms, particularly through-composed which only introduced new material.
