INTERACTIVE MUSIC SUMMARIZATION SYSTEM BASED ON GTTM
My talk presents a music summarization system called "Papipuun."
Papipuun performs quick listening in a manner similar to a stylus
skipping on a scratched record, but the skipping occurs correctly
at punctuations of musical phrases, not arbitrarily.
First, I would mention a method for representing polyphony based
on time-span reduction in the generative theory of tonal music
(GTTM) and the deductive object-oriented database (DOOD). The
operation, least upper bound, plays an important role in similarity
checking of polyphonies represented in our method. Next, I would
talk on the system operation of Papipuun. In a preprocessing phase
of Papipuun, a user analyzes a set piece by the time-span reduction,
using a dedicated tool, called TS-Editor.
For a real-time phase, the user interacts with the main system,
Summarizer, to perform music summarization. Summarizer discovers a
piece structure by similarity checking. When the user identifies the
fragments to be skipped, Summarizer deletes them and concatenates
the rest. Papipuun can produce the music summarization of good
quality, reflecting the atmosphere of an entire piece through
interaction with the user. I will demonstrate Papipuun during my
presentation.
