Recording, transpose and sources
Upload the recording
Chordingly aligns the sheet, detects beats and downbeats, transcribes likely guitar notes, and builds a playable arrangement. The uploaded file is deleted immediately after processing; only the extracted analysis is retained.
Compact full-song arrangement of Muse's “Feeling Good,” using the recurring descending progression Bm–A–G–F#. Each verse lyric line spans one four-bar progression; chorus lines share the same four-bar cycle, with the final “And I'm feeling good” completing a second cycle. The outro uses two cycles.
Timing check: At the inferred 72 BPM in 4/4, 59 bars take about 196.7 seconds, matching the 199.76-second recording within the requested tolerance. Adjacent full-bar chord events were paired because the literal interpretation exceeded the verified recording duration.
Expected about 60 bars; arranged 46.0 bars (about 153 seconds, recording 200 seconds).- Key
