Medieval music began in about what year? 4000 bce 1 ce 500 ce 1600 ce

Atypical scale usually consists of one of pitches. 1. rhythm 2. octave 3. key 4. series

The opening section sounds marchlike, with accented beats and alternations between instrumental groups. eventually, a total change of character marks a short, new section. at approximately which time interval from the beginning does this appear?
