How many times can a specific pitch appear in a tone row?

Answer 1

In a twelve-tone row, each pitch can appear only once, as the row consists of all twelve pitches of the chromatic scale arranged in a specific order without repetition. This means that no specific pitch can appear more than once within the same row. However, the row can be manipulated through various techniques such as transposition, inversion, and retrograde, allowing the same pitches to be used again in different contexts.
