The comparison

The harp plays a flourish, and four horns begin the dance. Stokowski’s Philadelphia orchestra and Robinson’s London players keep Tchaikovsky’s scoring, in which the violins then take over. Lawrence Odom’s concert-band arrangement gives the string parts to wind players.

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.

  • Stanford Robinson, National Symphony Orchestra: match score 0.968. Matched passages available.
  • United States Air Force Band: match score 0.952. Matched passages available.

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