Which artist (b. 1930), credited with changing the face of the american musical, developed a new style of the form featuring disturbing plots, an ironic tone and sophisticated intricately, rhymed lyrics? a. stephen sondheim b. graham wilson c. peter brook d. peter shaffer?

A.stephen sondheim is the correct answer cause i got the answer for final exam last year

why are there few examples of totem poles from before 1900

hope this !

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
