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. Cohen [Outro] | | |
