Song Structure
Songs are organized into sections — verse, chorus, bridge, and more — that serve different roles in the emotional arc. Chord charts use bracket notation to show when chords change relative to lyrics, and transposition lets you shift everything to a different key.
Song Sections
| Section | Role |
|---|---|
| Intro | Sets the mood, often instrumental |
| Verse | Tells the story with new lyrics each time |
| Pre-Chorus | Builds tension before the chorus |
| Chorus | The emotional peak, most memorable part, lyrics repeat |
| Bridge | Provides contrast, usually appears once |
| Solo | Instrumental showcase over verse or chorus chords |
| Outro | Closes the song, winds down energy |
The most common form is Intro-Verse-Chorus-Verse-Chorus-Bridge-Chorus-Outro. The verse-chorus dynamic works because each verse builds anticipation that the chorus releases. The bridge interrupts just when things might become predictable, refreshing the listener's ears.
Chord Charts
A chord chart shows chord changes above lyrics using bracket notation: [G]Somewhere [Em]over the [C]rainbow. The bracket tells you when to change chords. Charts show which chords to play and when to change, but leave voicing and strumming to the performer.
Transposing Songs
Transposing shifts every chord by the same number of semitones. A song in G (G-C-D-Em) transposed up 2 becomes A (A-D-E-F#m). The feel is identical — only the pitch level changes. The most common reason is adjusting for a singer's vocal range.
In ChordColor
The Songs app reads chord charts with bracket notation, displays each chord with interval colors, supports real-time transposition, and includes a metronome. Section labels (Verse, Chorus, Bridge, etc.) are recognized and displayed as headers.
