Western music: same size sections: intro+ABABCB+outro

introduction (intro), verse, pre-chorus, chorus (or refrain), verse, pre-chorus, chorus, bridge ("middle eight"), verse, chorus and outro. 

The formal sections found in songs are the verse, chorus, bridge, and refrain

The foundation of popular music is the "verse" and "chorus" structure

- Repeated sections: both chorus and verse music repeats.
- Chorus/refrain/hook/sthayi/mukhada: repeated section with same lyric: repeated lyric = repeated section/part
- Verse = antara = must have same music but different lyric: repeated section with different lyric: different lyric
- bridge: a small piece of music that connects two sections of a music


Verse played first:

cadence: the melody element that give sense of rest. Usually the cadence ends at the key note

coda: end piece of music

ABABCB: verse1 + chorus + verse2 + chorus + bridge + chorus + chorus

interludes: instrumentals connecting main sections or parts of a section with instrumentals
