   Lesson 29 January 28th, 2022 Lesson 29 Lecture notes: Fugues are opening melodic ideas that become the theme of a song and are explored or variated as the song progresses.  Fugues are done in no less than two voices and can range up to five voices . A  subject is the opening melodic line or phrase in a fugue or invention . This opening line establishes the key / mood of a song and is imitated throughout the various voices in the music.  The point of imitation is when a melodic idea is played in one voice and then answered by another voice with the same idea . The point of imitation is an octave apart in an invention and is a fifth and octave apart in the first two points of a fugue . The subject of a fugue is followed by an answer or countersubject , which comes in two forms , namely real answers and tonal answers . They are usually transposed up a fifth or down a fourth . A real answer is a melodic idea that is an identical transposition of the fug

There are five types of binary forms , including simple binary , continuous binary , sectional binary , rounded binary , and composite binary . A quick way to tell if a song is in binary form is to look for repeat signs . A visual example of these symbols would be | |: :| | | |: :| | The simple binary form is when the second half or B section ends without returning to the beginning section of A . A visual example would be | |: A :| | |: B :| | . The sectional binary form is when the first section ( A ) of a song ends with a cadence ( PAC ) on the tonic of the primary key . This section can stand on its own due to being tonally complete . The continuous binary form is when the first section ( A ) ends with a cadence ( HC ) that is not on the tonic of the primary key . The rounded binary
