Serialism: Day Two

3.

Construct a 12 by 12 matrix for the prime form of the following twelve-tone row, given in pitch integers: 3, 7, 11, 1, 5, 0, 2, 10, 6, 4, 8, 9. Include labels for all row forms including all transposition levels (P\(\text{}_{0}\), R\(\text{}_{3}\), I\(\text{}_{8}\), RI\(\text{}_{6}\), etc.). Use note names in the matrix, not integers.

4.

For the following excerpt, determine P\(\text{}_{4}\) and identify each row form and statement. This example contains overlap.

5.

Referring to the twelve-tone row used to construct the matrix in the practice exercise above (3, 7, 11, 1, 5, 0, 2, 10, 6, 4, 8, 9), find the normal form and prime form for each discrete three-note set from the row, and provide an interval vector for each.

  1. Set 1: 3, 7, 11. Normal form: Prime form: Interval vector:

  2. Set 2: 1, 5, 0. Normal form: Prime form: Interval vector:

  3. Set 3: 2, 10, 6. Normal form: Prime form: Interval vector:

  4. Set 4: 4, 8, 9. Normal form: Prime form: Interval vector:

Answer
  1. Set 1: 3, 7, 11. Normal form: [3, 7, 11] Prime form: (048) Interval vector: 000300

  2. Set 2: 1, 5, 0. Normal form: [0, 1, 5] Prime form: (015) Interval vector: 100110

  3. Set 3: 2, 10, 6. Normal form: [2, 6, 10] Prime form: (048) Interval vector: 000300

  4. Set 4: 4, 8, 9. Normal form: [4, 8, 9] Prime form: (015) Interval vector: 100110
