What is the rule for a tone row?

What is the rule for a tone row?

Tone rows are designated by letters and subscript numbers (e.g.: RI11, which may also appear as RI11 or RI–11). The numbers indicate the initial (P or I) or final (R or RI) pitch-class number of the given row form, most often with c = 0.

What are the 4 types of tone rows that can be created?

The four types of row forms used in twelve-tone technique are prime (P), retrograde (R), inversion (I), and retrograde inversion (RI). The prime is the original row.

What is a scale that consists of intervals of a step?

A whole tone scale is a type of scale where each note is an interval of a whole step (tone) apart. It’s the complete opposite of the chromatic scale where every note is a half step (semitone) apart. The whole tone scale is a type of hexatonic scale which means it only has six notes.

What is tone system?

Tone systems and multipart patterns have a functional interrelationship in African music. In other words, the kind of multipart pattern occurring in singing or instrumental music is conditional on the type of tone system, and vice versa.

What kind of pitches is the composition of 12 tone scale?

The basic order for any one composition came to be known as its basic set, its 12-tone row, or its 12-tone series, all of which terms are synonymous. The basic set for Schoenberg’s Wind Quintet (1924) is E♭–G–A–B–C♯–C–B♭–D–E–F♯–A♭–F; for his String Quartet No.

Which composition was written using the twelve-tone method?

The basic order for any one composition came to be known as its basic set, its 12-tone row, or its 12-tone series, all of which terms are synonymous. The basic set for Schoenberg’s Wind Quintet (1924) is E♭–G–A–B–C♯–C–B♭–D–E–F♯–A♭–F; for his String Quartet No. 4 (1936) it is D–C♯–A–B♭–F–E♭–E–C–A♭–G–F♯–B.

What is the meaning of tone row in music?

In music, a tone row or note row (German: Reihe or Tonreihe), also series or set, is a non-repetitive ordering of a set of pitch-classes, typically of the twelve notes in musical set theory of the chromatic scale, though both larger and smaller sets are sometimes found.

What can a twelve tone row be used for?

A twelve-tone row might be used as a theme or as a source for motives. Chords might be derived from the row, or the row may be used for both thematic and harmonic purposes. We call the basic ordering, shown above for Op. 27, the prime form (P).

How many octaves are in a tone row?

The “set-complex” is the forty-eight forms of the set generated by stating each “aspect” or transformation on each pitch class. The all-interval twelve-tone row is a tone row arranged so that it contains one instance of each interval within the octave, 0 through 11.

How is a tone row created in a trichord?

In this tone row, if the first three notes are regarded as the “original” cell, then the next three are its retrograde inversion, the next three are retrograde, and the last three are its inversion. A row created in this manner, through variants of a trichord or tetrachord called the generator, is called a derived row.
