Acoustic Automatic Accompaniment System for Musical Performance with Errors and Arbitrary Repeats and Skips

Tomohiko Nakamura, Eita Nakamura, and Shigeki Sagayama (The University of Tokyo)

We propose a system that can synchronize musical accompaniment automatically to a human performance with insertion/deletion/substitution errors and arbitrary repeats/skips in real time [1].

Accompanying to Human Performance during Practice

Accompanying to Human Performance with a deletion error

Accompanying to Human Performance during practice

  • A Repeat and tempo changes
  • Some Repeats
  • Many Errors and Repeats in short time (00:39 to end)

Whole score: Do-Re-Mi

The parts highlighted in pink are played by the human, and the others are played by the proposed system.
