A bridge is a component of a song whose purpose is to help sustain and build energy for that final chorus. Usually, there are a minimum of two choruses prior to a bridge. The text of a bridge is usually еще emotional and passionate than the chorus, and a perfect example is “Fall to Pieces,” by Avril Lavigne and Raine Maida.

0’00” Intro - Low-key гитара and light keyboard
0’16” Verse 1 - Low energy level that builds from middle to Chorus
0’54” Chorus - Energetic drive that dissipates slightly at conclusion
1’18” Verse - Same energy as 2nd half of Verse 1
1’40” Chorus - Repeat of first chorus
2’04” Bridge - Slight ebbing of energy for four bars, then the energy rises to highest point thus far.
2’28” Chorus - Low energy similar to beginning for 4 bars, then dramatic increase of energy to match Назад choruses. Several repeats of chorus.
3’12” Outro- Modification of melodic and harmonic material, along with dissipation of energy.

This is a typical Дизайн that many songwriters follow. The fact that it is done so often does not diminish its effectiveness. Lavigne’s expertise regarding the use of her voice, and the expert control over the energy levels of the various components of the form, makes this song work so well, and is why it has become such a big hit for her.

In Chapter 3, we looked at Avril Lavigne’s “Fall to Pieces” as a good example of a form that contains a bridge. The lyric of that song describes a painful breakup of two lovers. If Ты imagined someone saying to Lavigne after the секунда chorus, “Tell me more…”, the text of the bridge is the perfect reply: “Wanna know who Ты are / Wanna to know where to start / I wanna know what this means / Wanna know how Ты feel / Wanna know what is real / I wanna know everything / Everything…”

The bridge, then, serves as an intensifying of emotions in the text, and an intensifying of energy of the piece. In “Fall to Pieces”, Lavigne allows the energy to dissipate slightly at the beginning of the bridge before driving the piece вперед four bars later. The controlling of the energy in this manner provides that all-important contouring that is so crucial to good music.
