Overview
Key: G major · Chords used: 14 · Sections: 15
Where these chords come from: an expert transcription of the original recording made for the Uspop2002 chord annotations (Music and Audio Research Lab, New York University). This page shows that transcription as-is: the analysis below is generated directly from it by code, not written by AI. Consecutive repeats of a chord are shown once, and the piano voicings are our playable arrangement of each chord symbol, not a note-for-note transcription.

Sources & accuracy
- Chords: the Uspop2002 chord annotations (Music and Audio Research Lab, New York University). Chord annotation of the original recording (Third Eye Blind), time-stamped by researchers; CC BY 4.0 via ChoCo.
- Section names: this annotation doesn't name verses or choruses, so they aren't guessed. Instead, code used the chord timings to find the bars and cut the song into 8-bar parts. Each part is labelled with the time it starts in the annotated recording (Third Eye Blind), and a part with exactly the same chords as an earlier one says so.
- The key was estimated by code from the chords; this annotation doesn't state it.
- Not verified: only one expert transcription of this song is available so far.
- Rhythm and chord durations aren't shown; each step is one chord change.
