The comparison

The piano opens with a series of chords, then moves into running notes beneath a melody for strings and clarinet. Later the soloist plays a theme of its own in E♭ major. Rachmaninoff’s 1929 Philadelphia performance and Richter’s 1959 Warsaw recording are compared here over the opening disc side.

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.

  • Rachmaninoff, Stokowski, Philadelphia Orchestra, 1929: match score 0.934. Matched passages available.

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