The inverse of a given fragment of melody is the fragment turned upside down—so if the original fragment has a rising major third (see interval), the inverted fragment has a falling major (or perhaps minor) third, etc. (Compare, in twelve-tone technique, the inversion of the tone row, which is the so-called prime series turned upside down ...
In music theory, contrapuntal motion is the general movement of two or more melodic lines with respect to each other. [1] In traditional four-part harmony, it is important that lines maintain their independence, an effect which can be achieved by the judicious use of the four types of contrapuntal motion: parallel motion, similar motion, contrary motion, and oblique motion.
The principles of strict counterpoint constitute one of the fundamental components of Schenker's musical theory (see Schenkerian analysis).For Schenker, the study of counterpoint is the study of voice leading; in particular, contrapuntal theory is separate from and independent of harmonic theory, which is concerned with scale-steps (see Harmony).
Voice exchange is also used in Schenkerian analysis to refer to a pitch class exchange involving two voices across registers, one of which is usually the bass. In this sense, it is a common secondary structural feature found in the music of a wide variety of composers. [12]
In music, an invention is a short composition (usually for a keyboard instrument) in two-part counterpoint. (Compositions in the same style as an invention but using three-part counterpoint are known as sinfonias. Some modern publishers call them "three-part inventions" to avoid confusion with symphonies.)

It can also mean improvisation.) adagietto Fairly slowly (but faster than adagio) adagio Slowly adagissimo Very, very slowly affannato, affannoso Anguished affetto or con affetto with affect (that is, with emotion) affettuoso, affettuosamente, or affectueusement (Fr.)
The second part, on Musica Pratica, is the section of this treatise where the author presents his instruction on counterpoint, fugue, double counterpoint, a brief essay on musical taste, and his ideas on composing sacred music, writing in the a cappella and in the recitativo style. This part is in the form of a dialog, between a master ...
Voice leading developed as an independent concept when Heinrich Schenker stressed its importance in "free counterpoint", as opposed to strict counterpoint. He wrote: All musical technique is derived from two basic ingredients: voice leading and the progression of scale degrees [i.e. of harmonic roots]. Of the two, voice leading is the earlier ...
