Beethoven: the exposition repeat

The same recording plays the exposition and its written repeat.

Three short Gs fall on a held E♭, then three Fs on a held D. At Beethoven’s repeat sign the orchestra plays all 124 bars again, including the pauses, the horn call and the quiet violin tune in E♭ major.

Passages

Passages A and B, bar by bar

Choose A, B or both; playback stops at the end of each passage.

The score, bar by bar. Matching bars share a column; colours separate the voices. Shading marks a written change, and hatching marks a bar with no counterpart. Note lengths come from the score, stretched to fit each recorded bar.

In the score

Written changes

Choose a written change to play up to three bars from each passage.

No written changes

The repeat sign sends the players back through the same notes and markings; the two passages are identical in the score and can differ only in performance.

In the recording

Timing and volume

Differences between the two passages come from the score, the players, their instruments and the recording.

The 124 matching bars take 100.5 seconds on return and 101.9 seconds the first time — 1% shorter.

A higher point means a longer bar, including any pauses or added notes. Gold is A; dashed blue is B. The chart shows the bars selected above.

Chart method

Each bar is timed from its aligned start to the next bar. The final bar runs to the end of the recording, including the dying sound.

The volume chart averages the recording’s normalised amplitude samples, taken twice a second, within each bar. It shows changes within this recording.

Totals include matching bars only. Columns with a hatched gap are left out.

All bar measurements

Seconds and average amplitude; numbers in brackets identify repeats. A dash marks a bar with no counterpart.

Sources & timing

How the score is timed

Public-domain LilyPond/MIDI → voice-aware performed event table; tuning estimated with librosa; Sync Toolbox 1.4.2 memory-restricted multiscale DTW at 50 frames/s, chroma + DLNCO. First/last attacks anchored by score-pitch energy rises in documented inspection windows; section anchors refined by DTW and checked against existing passage labels. Note-offs are warped notation, not measured key releases; final piano holds extend to an estimated decay threshold. No aural review. See tools/align/REPORT.md.

Automatic timings. These await checking by ear. Report a timing problem.
