RWC Music Database

Music Genre Database and Musical Instrument Sound Database

Overview
Introductiono We need commonly available DBs to advanceresearch into music information processingex) music understanding, source segregation,
music perception, encoding/compression, MIRo Three main purposes• Use DBs as a common benchmark
Compare and evaluate various systems• Stimulate research in corpus-oriented approach
Use statistical methods or learning techniques• Use DBs for research publication & presentation
Demos w/o conventional copyright restrictions
Include demo videos in conference CD-ROMs

RWC Music Databaseo Copyright-cleared music DB compiled

specifically for research purposes• Researchers can obtain and use
freely in common for research purposes(Note that our DB is not copyright-free even though
it is available for free for research purposes)• 315 pieces (27 CDs) + 50 instruments (12 DVDs)o Content: six component DBs• Popular Music DB (100 songs)
All originally composed and arranged
20/80 songs with English/Japanese lyrics• Royalty-Free Music DB (15 songs)
Well-known public-domain songs (with vocals)
originally arranged and recorded• Classical Music DB (50 pieces)
Public-domain pieces originally recorded
6 categories: symphony 4, concerto 2,orchestral 4, chamber 10, solo 24, vocal 6• Jazz Music DB (50 pieces)46 pieces originally composed and arranged
4 public-domain pieces originally arranged
3 categories: instrumentation variations 35,
style variations 9, fusion 6• Music Genre DB (100 pieces)• Musical Instrument Sound DB (50 instruments)

Previous Worko Other research fields have common DBs• Speech and image processing
Importance and significance of DBs
have been widely recognizedo Music information processing• Difficult to use music on market CDs
because of copyright issues• Musical pieces: no copyright-cleared DB
released for public use• Musical instruments: there are DBs- McGill University Master Samples- University of Iowa Musical Instrument Samples

There is still a need fora large-scale common DB

Design Policy
o Content• Include as many realistic pieces andmuch variety (genres, moods, tempi, etc.) as
our production resource constraints allowedo Copyrights of musical pieces• Obtain all necessary copyrights andassociated legal interests related to the DB

to make the DB available to researchers• All newly performed, sung, and recorded• Music Genre DB
27 public-domain pieces + 73 original pieces
composed and arranged for this DB

o SMFs (Standard MIDI Files) and lyrics text files• Prepare transcribed SMFs for all pieces• Valuable because they can be freely used
for research purposes
as effective substitutes for scores• Song lyrics are provided as text files

Conclusiono RWC Music Database is now

complete with the six component DBs• Built in fiscal 2000 and 2001 by theRWC Music Database Sub-Working Group(chair: Masataka Goto) in the RWCP
(Real World Computing Partnership) of Japan• We hope that our DB is a first step toward theconstruction of DBs for specialized purposes andwill accelerate progress in the field of research
