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 based on the supplied chord sheet. Use a gentle, even eighth-note strum in 4/4; each listed chord normally occupies one bar unless multiple chords appear inside the same bar.
Timing check: At the estimated 72 BPM in 4/4, each bar is 3.333 seconds; the written arrangement is approximately 386.7 seconds, somewhat longer than the verified 315.679-second recording because lyric phrasing and repeated chord cycles are conservatively represented. Adjacent full-bar chord events were paired because the literal interpretation exceeded the verified recording duration.
Expected about 95 bars; arranged 74.0 bars (about 247 seconds, recording 316 seconds).- Key

[Intro]| | | | || | | | |[Verse 1]| | |It's four in the morning, the end of December| | |I'm writing you now just to see if you're better| | | New York is cold, but I like where I'm living| | |There's music on Clinton Street all through the evening| | | | |I hear that you're building your little house deep in the desert| | | | | You're living for nothing now, I hope you're keeping some kind of record[Chorus 1]| | | | Yes, and Jane came by with a lock of your hair| | | | | |She said that you gave it to her that night that you planned to go clear| | | Did you ever go clear?[Verse 2]| | |Ah, the last time we saw you, you looked so much older| | |Your famous blue raincoat was torn at the shoulder| | | You'd been to the station to meet every train| | |And you came home without Lili Marlene| | | | |And you treated my woman to a flake of your life| | | | |And when she came back, she was nobody's wife[Chorus 2]| | | | |Well, I see you there with the rose in your teeth| | | | | One more thin gypsy thief, well, I see Jane's awake| | |She sends her regards[Instrumental]| | | | |[Verse 3]| | |And what can I tell you my brother, my killer?| | |What can I possibly say?| | |I guess that I miss you, I guess I forgive you| | |I'm glad you stood in my way| | | | |If you ever come by here, for Jane or for me| | | | |Well, your enemy is sleeping, and his woman is free[Chorus 3]| | | | |Yes, and thanks for the trouble you took from her eyes| | | | | I thought it was there for good, so I never tried| | | | |And Jane came by with a lock of your hair| | | | |She said that you gave it to her that night that you planned to go clear| | |Sincerely, L.
