The comparison

The first D♭ major melody is a single line above an accompaniment of broken left-hand figures. The right hand soon adds a second voice in thirds and sixths, and the melody is more heavily ornamented at each return.

Passages

Passages compared

Each version plays in card order, for up to 12 seconds of reference music or until the next marked passage, whichever comes first.

  1. 01

    Opening melody

    0:05 in the reference

    The melody begins on F above broken chords in D♭ major. The right hand holds long notes over six-note figures in the left hand.

  2. 02

    Melody in thirds

    0:42 in the reference

    The right hand plays the melody in thirds as the bass moves towards B♭ minor.

  3. 03

    First return of the melody

    1:56 in the reference

    F returns above a low D♭. The opening melody returns, with new ornaments on its long notes.

  4. 04

    Third statement of the melody

    3:26 in the reference

    The melody returns for the third time; its continuation becomes a long flourish that climbs and falls across the keyboard.

  5. 05

    Coda over a D♭ pedal

    4:40 in the reference

    The bass holds D♭ while pairs of notes descend above it, marked dolcissimo — very sweetly.

How the recordings are matched

The matching follows sequences of pitches, using a method called dynamic time warping. Every recording is mapped to the reference, so switching between two versions goes through that shared clock. Where several reference times match one point, the middle time is used.

  • Vladimir de Pachmann, 1925: match score 0.954. Matched passages available.

Switching stays within the matched span, and trimmed recordings keep their original clock times. Match scores describe similarity in the sound.
